Executive Summary
The Supplemental Nutrition Assistance Program (SNAP) is one of the largest components of the social
safety net in the United States providing more than $69 billion in benefits in fiscal year 2014. Ensuring
that program participants are not receiving assistance in two states at once also referred to as dual
participation is an important factor in maintaining program integrity and public support for SNAP.
Throughout the history of the program, states have been limited in their ability to access information on
applicants’ eligibility in other states, making prevention of dual participation difficult. Furthermore, the
processes employed by states to communicate with other SNAP agencies regarding an applicant or
recipients’ eligibility status have been inefficient, and can result in a less than optimal level of customer
service.
The Mississippi Department of Human Services contracted with Public Consulting Group, Inc. (PCG) to
evaluate the National Accuracy Clearinghouse (NAC) a technology-based solution designed to curb
interstate dual participation in SNAP through a shared database of eligibility information that is updated
daily. The software for the NAC was developed by LexisNexis, also under contract with the State of
Mississippi. From May 2013 to August 2015, PCG worked with five pilot states Mississippi, Louisiana,
Florida, Alabama, and Georgia to assess the technical capacity of the NAC, states’ success in utilizing the
tool and implementing the accompanying business rules, and the cost savings if any associated with
adoption of the NAC solution.
This final report is the fifth in a series of documents produced by PCG as part of the NAC evaluation, and
integrates key findings from previous reports. The timeline below documents key project phases and
summarizes evaluation reports to date.
The evaluation focused on four central research questions:
1. Has the NAC resulted in a reduction in dual SNAP participation?
2. How effective have states been in utilizing the NAC to prevent dual SNAP participation?

3. How does the NAC compare to the use of PARIS?
4. What is the NAC’s return on investment?
Impact on Dual Participation. Comparisons of dual participation prevalence before and after the pilot
show a reduction occurred in all five pilot states, but with large variations in magnitude. Alabama and
Mississippi have had the largest declines (81 percent); Louisiana has also had a significant reduction (71
percent) in dual participation. Florida and Georgia have experienced a (relatively) small reduction (27
percent).
Effectiveness in Utilization of the NAC. The ability of pilot states to utilize NAC data to prevent dual
participation from occurring has varied greatly. Alabama and Mississippi’s prevention efforts have been
extremely successful, with consistently less than 10 percent of possible instances resulting in dual
participation. These percentages translate into the reductions in prevalence the states have realized.
While Louisiana’s efforts have not been as consistent, less than 20 percent of matches on average turn
into dual participation. Georgia and Florida have had lower levels of success at preventing dual
participation with 30 45 percent of matches resulting in dual participation.
Comparison of NAC and PARIS. The Public Assistance Reporting and Information System (PARIS)
presents states with some tools to reduce SNAP dual participation; however, the NAC is a more robust
and effective means for curbing SNAP dual participation. The advantages and limitation of PARIS were
identified by PCG as a part of site visits that occurred during the pre-pilot phase and are also documented
in previous reports by the General Accounting Office and Health Systems Research, Inc.
1
Specifically, the
NAC surpasses PARIS in the capacity to support the prevention of dual participation, supports constructive
interstate communication, allows for easier identification of “false positives,” and identifies individuals
that would not be flagged by matching only on Social Security Numbers.
Return on Investment. The net impact of the NAC during the pilot phase totaled approximately $5.6
million in SNAP overpayment avoidance (100% federal dollars). This estimate is conservative, as it only
focuses on the impact of prevention of dual participation and not the early detection of dual participation
that the NAC can also support. In addition, the estimate assumes that an individual will remain eligible in
one of the two states involved, and the calculation uses only matches that are almost certain to represent
actual dual participation. Most importantly, the estimate reflects the business processes that were in
place during the pilot. As states modify their approaches and improve system integration, the degree that
they are able to stop dual participation before it begins is expected to increase. Estimates of the savings
realized if the NAC were implemented nationwide average more than $114 million annually less than
two-tenths of one percent of total SNAP benefits issued annually, but a significant amount nonetheless.
Recommendations
The five NAC pilot states have implemented the tool in significantly differently ways, and have realized
different levels of success. Those that have achieved superior outcomes provide a set of best practices
that should be considered as use of the NAC continues in the current states and as expansion beyond the
pilot is explored. Furthermore, the pilot states have learned lessons that should be heeded by any state
current or futureintending to use the NAC. The best practices, lessons learned, and opportunities for
improvement may be identified under three general categories: technical recommendations, business
processes, and staff utilization.

Technical Recommendations
States should automate to the greatest extent possible. This includes integration with state
eligibility systems, use of web services for state-NAC interfaces, automated emails requesting case
action, and system edits to ensure staff take appropriate action prior to case authorization.
Checking on individuals being added to an open SNAP case is an important component of
prevention. Data suggests that nearly half of dual participation falls into this category, and the
procedures for inquiring about benefits in another state that apply to new applicants may not be
followed in these instances. The integration of the NAC with state eligibility systems should
include automated look-ups that occur before the new household member is added to an existing
case.
States should ensure that IP address issues do not limit access to the NAC. Some state staff,
especially those working from home, experienced difficulty accessing the NAC. These issues
occurred because not all IP addresses were accounted for, and users were denied access by the
NAC’s firewall. A thorough accounting of all potential users and their IP addresses is an important
step in NAC implementation planning.
“Social Security Number-only” matches should be treated differently. When the only matching data
element between state data is a Social Security Number, it is likely that dual participation has not
occurred. These matches often occur because one digit of the SSN has been entered incorrectly
in the state eligibility system. In these situations, automation in place for other types of matches
is not advisable, and states should confirm the accuracy of data entry before contacting another
state or the client.
Business Processes
States should have a robust process for addressing dual participation when prevention efforts fail.
In some instances, the business processes implemented by pilot states or worker error result in
dual participation occurring despite the availability of the NAC. The establishment of an internal
state work group responsible for follow-up and the automation of reports supports early
detection and reduction in the length of dual participation that does occur when dual
participation is not prevented.
Additional standardization of business processes would support improved outcomes. These include
consistent treatment across states of different match types, timely submission of contributory
files, and common naming conventions for state email addresses.
The requirement to notify a state of case closure in all instances should be reconsidered. The initial
business rules limited the number of email exchanges required between states to support timely
case closure and removal of individuals. Due to inconsistency in states’ abilities to meet required
timeframes for case action, these rules were revised. As states improve their capacity to utilize
NAC data, the revision should be reconsidered.
States should explore a wider use of “passive matches. The NAC notifies states when a query of
the system has been conducted by another consortium member. Although these notifications
were not used to a large degree during the pilot, they present an opportunity for additional
streamlining of communication.
Staff Utilization
Separate staffing models are needed for the initial match and ongoing operations. When states join
the NAC consortium, the initial matching process will identify many instances of apparent dual
National Accuracy Clearinghouse (NAC) Evaluation | Final Report

participation. States should dedicate staff to the effort to address these situations, which includes
the establishment of overpayment claims.
Comprehensive front line staff training is essential to successful implementation. Regardless of the
specific processes a state implements to access and use NAC data, front-line staff must have an
understanding of their responsibilities and the information needed to communicate effectively
with other states.
In conclusion, the evaluation found that the National Accuracy Clearinghouse has supported a decrease
in dual SNAP participation in the five pilot states and gives states the capacity to prevent dual participation
to an extent not available through the PARIS match. A strong argument can be made that the pilot savings
and the NAC’s potential warrant continuation and expansion of the project.

Background / Project Overview
The Supplemental Nutrition Assistance Program (SNAP) is a key component of the social safety net in the
United States, and ensuring that program participants do not receive benefits in more than one state in a
single month is an important component of program integrity and maintaining public support for the
program.
2
When someone does receive SNAP in two or more states in the same month or in two or more
households within the same State
3
, it is referred to as dual participation.
Individuals working at all levels of the SNAP program have long suspected that dual participation could be
more effectively limited through an improved process for data sharing between states. SNAP caseworkers
also express frustration with the time required to communicate with other states to verify eligibility status,
which can impact applicants’ ability to receive benefits quickly.
Several southern states tested the concept of data sharing through the “buddy state” model as early as
2008 as a result of lessons learned operating D-SNAP programs following Hurricane Katrina. The
establishment of the Partnership Fund for Program Integrity Innovation by the Office of Management and
Budget (OMB) in 2010 created the opportunity for funding a more comprehensive solution.
The following year, OMB awarded the United States Department of Agriculture (USDA) Food and Nutrition
Service (FNS) $2.5 million with the goal of reducing improper payments that occur due to dual
participation in SNAP. This grant funded the development of a searchable database the National
Accuracy Clearinghouse (NAC) to support near real-time sharing of eligibility information. Subsequently,
Mississippi was awarded the funding to lead the project on behalf of a consortium of contiguous states
(also including Alabama, Florida, Georgia, and Louisiana).
Scope of the Problem
With limited information on the scale of dual participation, the size of the problem that the NAC was
designed to address was not entirely clear at the outset of the project. Table 1 demonstrates one approach
for quantifying the scale of dual SNAP
participation prior to the implementation of
the NAC. Here, the number of dual
participants
4
in May 2014 is divided by the
total number of active SNAP recipients in the
same month (using data only made available
after the development of the database). Note
that the dual participant statistics only
represent the instances identified with the
other four pilot states and do not include data
from the other 45 states, Washington D.C.,
and the territories.
2
SNAP regulations at 7 CFR 273.3 (a) dictate that “No individual may participate as a member of more than one
household or in more than one project area, in any month…” An exception exists if the individual is a resident of a
shelter for battered women and children and was a member of a household containing the person who had abused
him or her.
3
State eligibility systems generally support the ability to identify dual participation within state borders (intrastate);
the NAC was conceived to address interstate dual participation.

The statistics reflect a relatively low occurrence of dual participation ranging from less than one-tenth
of one percent of Louisiana’s eligible individuals in May 2014 to just below two-tenths of one percent of
Georgia’s. However, in a program as large as SNAP - with total allotments exceeding $69 billion in FY 14 -
even small percentages of benefits issued in error translate into a significant improper expenditure of
taxpayer dollars.
The NAC Solution
The premise of the NAC is simple states contribute daily files of their active SNAP participants in a
common format to a centralized database. The states then submit information requests to the database
on program applicants, and the NAC looks for overlapping information on a range of data points, such as
Social Security Numbers, names, and dates of birth (DOB), to determine if the individual is already a SNAP
recipient in another state.
The following example demonstrates how the NAC can
prevent dual participation (and what happens when it
does not):
John Doe is receiving SNAP in Alabama. He moves
out of state without notifying his caseworker, and
his SNAP case remains active in Alabama.
John applies for SNAP in Louisiana. When his
application is registered there, an inquiry to the
NAC is completed to determine if he is receiving
SNAP in any of the other four pilot states. A match
(see box) is returned that confirms he is an active
SNAP recipient in Alabama.
John’s caseworker in Louisiana receives
the information from the NAC as part of the eligibility determination process. SNAP benefits
in Louisiana are not approved until case closure in Alabama is confirmed, and dual
participation is prevented.
John’s caseworker in Louisiana ignores the information in the match and approves SNAP
benefits without notifying Alabama. Dual participation (a collision) occurs.
The NAC provides participating states with data on both matches (to support the prevention of dual
participation) and collisions (to end dual participation as soon as possible when it does occur).
The Matching Process
When a state submits an individual to the NAC to perform a search
5
, the database first determines if a
LexID is associated with the input information. The LexID is a unique, 12-digit identifier assigned after a
successful identity resolution, generated by comparing input information provided by Participating States
across billions of unique public records. Through identity analytics, input information is resolved to a single
5
The submission occurs most commonly through an automated process in which all demographic information is
utilized, and less often via manual portal query in which a user enters selected demographic elements for matching.
Match: An instance in which a state identifies an
individual who is already receiving SNAP or D-
SNAP benefits in another state; generally in the
context of dual participation prevention (prior to
approval of benefits in a second state).
Collision: An instance in which dual participation
receipt of SNAP or D-SNAP in two or more states
in the same month - has occurred. The NAC
supports next-day identification or “early
detection” of dual participation when it does
occur.

11
individual with an extremely high degree of accuracy
6
. The level of accuracy is captured in the score of 0-
100, with 100 representing the highest confidence. If the LexID is associated with the input information,
it compares that ID to all the LexIDs currently associated with the NAC. When matches for dual
participation are identified, LexisNexis adds applicable match codes, such as Full/Partial Name, SSN, DOB
and Address to provide additional match information and to ensure that all matches include match code
combinations (rather than a LexID score only).
Because identities for a large portion of SNAP-eligible individuals cannot be assigned a LexID (children in
particular, who have limited public records), LexisNexis matches directly with Full/Partial Name, SSN, DOB
and Address to return dual participation results, also in the form of match code combinations. For
example, a match code combination of “NSD” indicates the name, Social Security Number, and date of
birth are the same in both states. In practice, states use both the match code combinations and to a
much lesser degree LexID scores to dictate the process to be followed in addressing a match, or whether
a match is investigated at all.

The NAC Evaluation
Summary of Previous Reports
This final report is the fifth in a series of documents produced by Public Consulting Group (PCG) as part of
the NAC Evaluation. The Pre-Pilot Report, submitted in July 2013, found that the processes in place for
identifying and acting on dual participation prior to the NAC were not particularly advanced. Consortium
states generally relied on client self-attestation and caseworker experience to prevent dual participation.
Use of the optional quarterly PARIS match of common Social Security Numbers to identify possible
instances of dual participation varied drastically, with two states not utilizing the match at all for SNAP
recipients. The report also documented states different policies and procedures for verifying out of state
participation, ranging from placing the onus for obtaining verification mostly on the client to relying
heavily on state staff to confirm eligibility status.
Perhaps most significant from an evaluation standpoint was that the extent to which potential dual SNAP
participation was being prevented either through the client’s own reporting or states’ pre-authorization
business practiceswas not captured in any consistent manner within or among states. In states where
denial and closure codes from eligibility systems were analyzed, more dual participation actions were
associated with closures than denials, suggesting a lack of effectiveness in pre-authorization identification
of eligibility in another state.
The second evaluation document (Three Month
Report) was submitted in September 2014. This
report described the business rules and processes
states put in place to utilize the NAC, illustrated
the prevalence and characteristics of dual
participation in the pilot states at the point the
NAC became operational, and provided initial
observations on the successes, challenges, and
lessons learned in the months leading up to the
availability of the NAC tool and the first three
months following its implementation.
The third evaluation document (Six Month
Report) was submitted in December 2014.
It included analysis of the changes in dual SNAP participation between a pre-implementation period
(March-May 2014) selected to represent the prevalence of dual participation immediately preceding
implementation and post-implementation period (September-October 2014), made preliminary
observations regarding linkages between implementation success and business process design, and
identified areas of improvement in the communication between states.
The fourth evaluation document (Twelve Month Report), submitted in June 2015, provided an update of
pilot state business processes at the conclusion of the pilot, an analysis of the likelihood that matches
with certain common or similar demographic information do in fact represent the same individual;
statistics regarding the frequency of dual participation for the months of August 2014 to March 2015; and
a preliminary analysis of pilot state effectiveness in preventing dual participation for the months of August
2014 through March 2015.
A Note on the NAC and D-SNAP
The need to determine if individuals applying for
Disaster SNAP benefits were already active in another
state was an important impetus for the development of
the NAC. However, no disasters warranting
implementation of a D-SNAP effort occurred during the
NAC pilot. The evaluation was therefore unable to
draw any conclusions with D-SNAP data regarding the
NAC’s ability to prevent dual participation under
disaster circumstances.

Analyses included in the Three, Six, and Twelve Month Reports are inserted and expanded throughout
this document. The most relevant findings and observations are also integrated into the
Recommendations section of the report.
Data Sources
Numerous analyses have been conducted as part of the evaluation, and specific methods used are
addressed where applicable throughout the report. The following provides a summary of the data and
information sources utilized to support evaluation observations and findings.
Pre-Pilot Files: PCG received files containing data on individuals identified as possible dual participants
by the NAC’s matching algorithm for the benefit months of September 2013 through May 2014 (the last
month before the pilot began). Statistics from these months provide meaningful baseline information as
it reflects the prevalence of potential dual participation in the months prior to the use of the NAC and can
be used to document how successful pre-NAC efforts to combat dual participation were in relation to the
pilot period.
Big Bang Files: On June 5, 2014, PCG received an Excel workbook created by LexisNexis containing all
collisions identified by the NAC for the month of June 2014 as of “go-live” (June 2
nd
) and the demographic
information associated with them
7
. This data, in conjunction with the supplemental data referenced
below, was used for a numerous calculations, including, but not limited to, the average/median length of
dual participation and the value of the SNAP allotment attributed to the dual participant.
Supplemental Big Bang Data: PCG modified the file provided by LexisNexis, preparing separate
documents for each of the five pilot states and adding data elements for the states to enter for each
individual identified as a possible dual participant. This data collection by the states occurred in two
“tiers”:
Tier One data collection consisted of:
SNAP allotment for entire case in benefit month
Household size in benefit month
Next recertification date
Total SNAP redemption for case during prior benefit month
Client eligibility date (to confirm information provided via administrative data)
Action taken/disposition
8
7
Additional dual participation would occur for June 2014 on applications approved and individuals added to cases
after the 2
nd
of the month. Those instances of dual participation were not a part of the Big Bang file.
8
Options provided for description of the action taken:
a) Client responded to contact letter -Individual removed and case remains open;
b) Client responded to contact letter - Individual closed and case closed;
c) Client responded to contact letter - Individual remains eligible;
d) Client DID NOT respond to contact letter - individual removed and case remains open;
e) Client DID NOT respond to contact letter - individual closed and case closed;
f) Case already closed OR individual removed; and
g) Match not valid.

Tier Two data collection included two sets of data:
Claims-related information on the individuals for whom Tier 1 data was collected; and
For individuals identified at the Big Bang whose only common data element is a Social Security
Number, an explanation/reason for the discrepancy in demographic information.
Match Search History (MSH) Files: Beginning in June 2014 and continuing through July 2015
9
, pilot
states provided PCG with daily Match Search History (MSH) files. Information on MSH files is organized
into four “Activity Typesdocumenting the previous days’ NAC activity for four categories of information:
1. Single: a record of requests (and resulting matches if applicable) for match information made by
states via NAC portal queries or via state eligibility systems connected to the NAC by batch or
real-time web service;
2. Batch: a record of requests (and resulting matches if applicable) for match information made via
batch process;
3. Passive: a notification informing a matching state that an initiating state conducted a search that
generated a match; and
4. Build-Time Collisions: A record of new collisions.
These files were used to identify the prevalence of, and state success in preventing, dual participation
during the pilot.
Qualitative Data: PCG collected qualitative data throughout the evaluation, primarily to gain
understanding of the business processes in place to address dual participation both before and after the
NAC became available.
In the pre-pilot phase, PCG conducted site visits in each of the five consortium states to explore the
processes states had in place for identifying and addressing dual participation prior to the NAC.
During pilot operations, PCG compiled regular updates from the pilot states on their internal rules
and processes. In addition, two “face-to-face” meetings were held. In these forums, states reported
on challenges and accomplishments that informed the ongoing evaluation work. In addition, SNAP
regulations, business rules developed and published jointly by pilot states, and technical requirement
documents authored by LexisNexis were referenced to support understanding of NAC
implementation.
Biweekly conference calls held throughout the project provided ongoing updates from pilot states, USDA-
FNS, and LexisNexis regarding policy, business process, and technical issues.
9
In order to determine if matches received during the pilot period became instances of dual participation, data
was collected for 2 months following the conclusion of the pilot.

NAC Business Rules and Processes
From the outset of the project, the pilot states understood the importance of establishing a set of
consistent business processes across the pilot that, if implemented successfully, would allow them to use
information received via the NAC to improve customer service, reduce worker effort, and prevent dual
participation. The pilot states and USDA-FNS collaborated to establish business rules that sought to
achieve those aims while maintaining and promoting access to SNAP and D-SNAP benefits for eligible
participants and compliance with regulatory requirements. States also recognized that due to
organizational capacity and the desire for some autonomy in decision-making, it would be necessary to
allow for the establishment of NAC-specific business rules and processes for some components of the
project. For example, how staff would access NAC information, the degree that NAC information would
be available through integration with existing eligibility systems, and the prioritization of certain types of
information provided by the NAC.
This section addresses the business rules and processes developed prior to pilot operations and their
maturation and adaptation that occurred during the pilot.
Common Business Rules
The common business rules - intended to be followed identically by all five pilot states - were designed to
address how states were to handle two general scenarios:
1. Active dual participation when NAC data indicates an individual is receiving SNAP in two pilot
states (a collision); and
2. Dual participation preventionwhen NAC data indicates an individual is receiving SNAP in one
state and is applying, but has not yet been approved, for SNAP benefits in a second state (a
match).
Active dual participation. One set of business rules addresses the process for communicating with clients
and states when individuals are identified through the NAC as potentially receiving SNAP in one or more
of the pilot states, also referred to as a “collision.”
Pilot states initially intended for information received through the NAC on active dual participants to be
treated as “verified upon receipt.” However, while that information would seemingly verify that an
individual was an active SNAP recipient in two states, it could not serve as verification of the state in which
he/she was actually residing. Therefore, the NAC information could not be considered verified upon
receipt. Accordingly, the business rules were written to direct the states involved to send a Request for
Contact Notice to the head of household. This notice was to include 1) the reason for the contact (that a
computer match indicated that one or more household members may be active in another state); and, 2)
a request for proof of residency and verification that SNAP benefits for the person/persons in question
have been terminated in the other state.
The process dictating that a contact notice be sent prior to taking action on the case represents a
departure from SNAP Simplified Reporting rules established in Section 6(c)(1)(d) of the Food and Nutrition
Act of 2008 (the Act). To address this issue, waiver requests were submitted by the pilot states and
approved by USDA (under Section 17(b)(1) of the Act) to allow adoption of the NAC business rules.
Without the waivers, states would have been prevented from acting on information that is not verified
upon receipt (NAC collisions specifically) until the next client contact.

Dual participation prevention. A second set of business rules was established for communication
between states when a match is received indicating an individual is already an active SNAP participant in
one of the pilot states but prior to authorization in the state receiving the match.
To reduce the overall work effort required to resolve a match, states developed business rules that
assumed certain actions would be taken within specified timeframes by their fellow pilot states.
Specifically, if the match was received prior to the 15
th
of a month the initiating state (see box) was
directed to assume that the matching state would
take action to close the case/remove the
individual prior to the issuance of the following
month’s benefits. This was a key feature of the
rules as they were originally implemented.
However, the pilot states discovered at a relatively
early stage of the pilot that the matching state was
not always able to take the action as dictated in
the business rules and dual participation occurred as a result. Accordingly, the rules were modified so as
to require an email response from the matching state prior to approval of SNAP in the initiating state.
The Common Business Rules in effect as of the conclusion of the pilot are found in Appendix A.
State-Specific Business Processes
The common business rules dictate that states participating in the pilot:
“…must submit ALL household member data
10
to the NAC prior to certification of benefits,
including any new household members. The only exception would be on expedited cases
where States may follow their own policy or procedure regarding the processing of the
initial months’ benefits.”
States have in fact implemented different processes in response to the flexibility offered in the common
business rules relative to expedited case processing. The processes that have been instituted to address
other business needs, and the level of automation developed to support the NAC, also vary significantly
from state to state.
Detailed descriptions of state-specific business processes are found in Appendices D and E. In Table 3
below key components of these processes each with impact on project outcomes are highlighted. The
impacts of incorporating these business processes or not are addressed in the Recommendations
section of this report.
10
Member data includes (but is not limited to) name, address (home and mailing), Social Security Number, gender,
race, ethnicity, and date of birth for the participant and additional information on the head of household.
Initiating State: the state in which an individual is
applying and has not yet been approved for SNAP.
Matching State: the state in which an individual is
already receiving SNAP benefits.

Treatment of Matches
A key question for states implementing the NAC concerns how matches are treated depending on their
“strength.” At a basic level, match strength represents the degree that commonalities in a data element
or elements suggest that an individual receiving SNAP or D-SNAP in one state is the same person receiving
the benefit in another. The matches that a state chooses to investigate and/or act upon impacts both the
efficiency and efficacy of the NAC in preventing and
identifying dual participation.
Table 4 documents the ten matching elements that, either
alone or in combination, suggest that individuals reported by
two or more states may be the same person.
Because some matching elements are stronger indicators
than others, and some combinations of these elements
when matched indicate a strong likelihood that the records
represent the same individual, match code combination
rankings (see Table 5) provide a means to prioritize and
organize data produced by the NAC. For example, the “NSD”
match indicates the full name, full SSN, and date of birth are
identical. If two states submit records in which an applicant
or recipient’s data matches on all three of these elements, it
is very likely that this is the same person.

“Top 5” match code combinations (in bold italic
in table 5) make up a significant majority of the
output from the NAC. For the period of August
2014 through May 2015, they accounted for
84.8% of matches.
13
With virtually no exceptions,
matches with these five code combinations have
been established as valid per feedback from the
pilot states and analysis. A review of Top 5
matches in which Mississippi was the second
authorizing state found that of 235 Top 5
matches, only 2 (<1%) were identified as invalid
(i.e. not representing a true match of the same
individual).
An analysis of the other 15.2% percent of
matches referred to as “6+” found that about 6 in 10 of those were valid. These include matches
generated based on the LexID that are not included in the combinations listed in Table 5. In fact, in some
instances there may only be one matching demographic element, but other public records data accessed
by LexisNexis generates a score indicating a likely match. Thus, when states choose to ignore the LexID
score and only address matches with a strength of 1-5, there is some dual participation that is missed.
Table 6 documents pilot states’ treatment of NAC data based on the match code combination.

Key Research Questions
The National Accuracy Clearinghouse (NAC) evaluation focuses on four central research questions:
1. Has the NAC resulted in a reduction in dual SNAP participation?
2. How effective have states been in utilizing the NAC to prevent dual SNAP participation?
3. How does the NAC compare to the use of PARIS?
4. What is the NAC’s return on investment?
The analyses conducted to answer the research questions utilize data related ONLY to inter-state
participation. The NAC does identify instances of intra-state dual participation as well. These are
generated when the NAC matches an individual who appears to be active in two cases in the same state.
However, intra-state dual participation is outside the scope of the evaluation and is not included in the
following analyses.
Has the NAC resulted in a reduction in dual participation?
Several months elapsed between the first submissions to the database and actual use of the NAC by the
states to prevent and identify dual participation. This provided the evaluation with pre-pilot data, which
allows for comparison of the frequency of dual participation before and after the NAC was available for
use by the pilot states.
Table 7 compares the prevalence of dual participation (Top 5 match code combinations) prior to pilot
operations to the final four months of the pilot (February - May 2015).

Reductions in dual participation have occurred in all five pilot states, but with large variations in size. It is
important to stress that these dual participation statistics are duplicative i.e. an instance reported for
one state is also included in the tally for the other state in which the individual is an active SNAP recipient.
A previous report referenced the symbiotic nature of dual participation in Georgia and Florida, and the
nearly-identical statistics in Table 7 reinforce that observation. On the other hand, the similarities in the
percentage reduction in Alabama and Mississippi (both 81%) appear to be the product of their practices
and not a reflection of their caseloads mirroring each other (note that the raw numbers are quite
different).

The analysis uses the final four months
of the pilot for comparison to the pre-
pilot months, assuming that a late-pilot
timeframe is more likely to demonstrate
how the NAC will impact dual
participation on an ongoing basis (as
states would have had time to adjust
and hone their processes). To test this
assumption, Figure 1 compares dual
participation entries and continuations
(see box at right) in the middle and late
stages of the pilot.

Middle (October 2014 thru January 2015) and Late (February May 2015) Stages of Pilot

The bar graphs show all five states reduced the number of entries and continuations as the project
matured. For example, Alabama averaged fifty fewer entries on average in the late phase compared to
earlier in the pilot (233, down from 283). Louisiana’s continuations fell 40 percent, from 199 to 120, over
the comparison periods. Improvement between middle and late stages of the pilot suggest that states
gained a better understanding of how to utilize the NAC over the pilot period, and supports the use of
late-pilot data in Table 7.

Reductions in dual participation could occur simply because fewer individuals are receiving SNAP benefits
overall. Table 8 illustrates another measure of the impact of the NAC on dual participation by comparing
the number of dual participants
17
as a percentage of eligible individuals in the month before pilot
operations began (seen previously in Table 1) to the same statistic captured in the last month of the pilot.

In each of the five pilot states, both the raw number and percentage of the caseload made up of dual
participants declined, suggesting that the drop is not primarily due to a reduction in the overall SNAP
caseload (which occurred in four of the five pilot states). For example, before NAC implementation, just
over one-tenth of one percent (.121) of SNAP recipients in Mississippi were dual participants; by May
2015, that percentage had dropped to .023.

How effective have states been in utilizing the NAC to prevent dual participation?
The primary goal of the NAC is to provide states with information that supports prevention of dual
participation in SNAP. The analysis in the previous section does not address which of the two states
involved in an instance of dual participation was in the best position to prevent it from occurring, and
whether they were successful. Here, matches received prior to authorization of SNAP benefits in a second
state are identified and tracked over a three month period to determine if they became collisions. This is
an indicator of how successful the second state has been in utilizing the NAC to prevent dual participation.
The relative success that pilot states have had in achieving the goal of prevention is assessed by identifying
the matches (opportunities to prevent dual participation) received in a given month and “following” those
same individuals in the state in which the match was received. By tracking these matches to see if a
collision eventually occurred, a determination is made of whether or not prevention efforts were
successful or not.
Figure 2 illustrates, for each pilot state, the percentage of Top 5 matches received in August 2014 through
May 2015 that became collisions. Unlike the statistics in Table 7, which are duplicative (i.e. a collision in
one state is also tallied as a collision in another), these percentages reflect the success rate of only the
state in which the individual is applying and not yet eligible (the initiating state). See Appendix B for
methodology used in this calculation
19
.
Figure 2
Percentage of Top 5 Matches that Became Collisions: August 2014May 2015
To summarize, two states Alabama and Mississippi have been extremely effective in preventing dual
participation, with consistently less than 10 percent of matches resulting in collisions. Louisiana’s
success rate, while not as consistent, has achieved similar results in some pilot months. Florida and
19
This analysis assumes that the 2nd authorizing state (initiating state) is primarily responsible for dual participation.
A limited number of collisions presumably occur because the 1st authorizing state (matching state) failed to take
action to close a case or remove an individual as requested by the initiating state.

Georgia have not been as successful in preventing dual participation, with 30-45 percent of matches
becoming collisions during the pilot.
The relative rates of success illustrated in Figure 2 align closely with what would be expected based on
the approaches states have taken to utilize NAC information. Mississippi has implemented a range of
processes that would tend to support better outcomes (such as integration with the eligibility system and
use of web services), whereas states with less successful outcomes have not put similar practices in place.
For instance, in Florida “there is no process in place to check the NAC if disposition on an application is
taken prior to processing of the overnight batch
20
and, with respect to the addition of new household
members in Georgia, the “caseworker typically does not become aware of the match until after benefits
have been authorized.The differences in business processes and systems integration not only provide at
least a partial explanation for the varied outcomes achieved by states, but also support a set of practices
that may be adopted to improve upon and maximize the effectiveness of the NAC.
20
For example, an application may need to be approved on the day it is registered in the eligibility system in order
to meet expedited processing timeframes. Absent a portal query or web services connection to the NAC, benefits
would be approved before the results of an overnight match with the NAC database is received.

How does the NAC compare to the use of PARIS?
The National Accuracy Clearinghouse is not the first effort to match public assistance data across states.
In 1997, the Public Assistance Reporting Information System, or PARIS, was initiated to identify individuals
who may be active participants in the same program in more than one state. In this section, the
differences between the NAC and PARIS are explored.
NAC and PARIS key differences
Multiple factors influence the degree that the NAC and PARIS are able to reduce dual participation
overpayments effectively and efficiently. The characteristics and limitations of the PARIS match were
identified during PCG’s pre-pilot site visits and in two separate evaluations of PARIS, conducted by the
General Accounting Office and Health Systems Research, Inc. (an Altarum Company)
21
. The distinctions
between the two solutions are considerable, and are detailed below.
Frequency of the data match. States may submit data to be matched for PARIS on a quarterly basis,
whereas the NAC database is updated daily with information on beneficiariesstatus (and may be queried
at any time).
Identification of the benefit month. A match generated via PARIS indicates an individual was eligible in two
states within a three month period. And, while the results of the PARIS match do document the dates that
the benefits in question were received, the process of determining if an actual overlap occurred is left up
to the states. The standard format for NAC contributory files includes the benefit month, and a match is
generated only if the match occurred for a specific month. So, unlike PARIS, the NAC provides states with
confirmation that a match represents overlapping SNAP receipt, and not just receipt in the same quarter.
The GAO Report includes the following relative to PARIS’ limitations:
“…participating states do not have adequate protocols or guidelines to facilitate critical
interstate communication. As a result, some states have reported problems that
compromise the effectiveness of the project, such as difficulty determining whether an
individual identified in a match is actually receiving benefits in another state.”
For example, if an individual is active in Mississippi in only the first month of a quarter and active in
Alabama in only the last month of a quarter, a match is generated and states must investigate further to
determine that in fact no SNAP eligibility overlap occurred.
Prevention vs. pay-and-chase. Perhaps the most significant difference between the NAC and PARIS is that
PARIS only identifies potential dual participation after it occurs, and sometimes several months afterward.
The GAO report specifically cited this as a limitation of PARIS, stating “…because the PARIS match is only
designed to identify people after they are already on the rolls, it does not enable the states to prevent
improper payments from being made in the first place.” Conversely, the NAC allows states to prevent dual
participation before it occurs by supporting the submission of data on SNAP recipients and applicants.
The graphic below illustrates the timeline associated with using PARIS to identify possible dual
participation. In this hypothetical scenario, an individual applied for and was approved for benefits in

Four months of dual participation
The four month spell of dual participation in this example (the red bars) assumes a quick turnaround on
the utilization of the PARIS data received in May; in many instances the dual participation would continue
beyond four months as the PARIS data is processed and/or the client’s actual circumstances are
investigated. This investigation includes a determination of whether overlapping eligibility occurred at all
as noted above, PARIS generates matches based on eligibility in two states within a quarter.
The same scenario is illustrated in Figure 4, except it illustrates the impact of near real-time data matching
for SNAP applicants that the NAC supports. When the client applied for SNAP in Alabama, the NAC was
available to confirm the individual already received SNAP in March in Mississippi. Therefore, SNAP
benefits in Alabama were authorized effective in April.

In addition, if a state’s business process and/or system integration prevents a NAC inquiry from being
conducted before an application is authorized (such as the need to approve expedited benefits on the day
the application is registered), the timing of the match is such that the spell of dual participation would be
one month instead of four.
Administrative Cost Avoidance. In addition to supporting the prevention of duplicate SNAP issuance, the
NAC model allows states to reduce costs associated with fraud/overpayment investigations, processing
claims, and recovering benefits, because the improper payment never occurs in the first place.

Demographic matching points. The PARIS match exclusively
uses the Social Security Number submitted by participating
states to identify possible dual participation if an exact SSN
match is not produced, no results are communicated to the
states involved. The NAC uses multiple demographic
elements and public records to establish matches that states
are able to prioritize based on the level of confidence that a
match truly represents the same individual.
Table 9 demonstrates the impact of the one Top 5 match
combination
22
that does not include an exact SSN match.
Because PARIS matches are generated only when SSNs are
exactly the same, none of the ninety-two matches identified
here would have been reported by PARIS (NPD matches
indicate an exact match on name and date of birth, and a
close - but not exact - match on SSN).
Several other matches albeit with lesser rates of validity than the Top 5 match code combinationsare
identified by the NAC and are not available to states through PARIS because they do not include an exact
SSN match. Table 10 provides information on the frequency and validity identified for these combinations
at the Big Bang. Note that instances in which the match codes in the first column are not included in
Table 5, the match was actually generated by additional public records information that support the
assignment of a LexID.

In addition to identifying matches that PARIS does not, the range of data utilized by the NAC provides a
high degree of certainty regarding the large majority of matches. This reduces the time and resources
required for follow up between states.

Case Study - Florida
The NAC evaluation Pre-Pilot Report included a review of the five pilot states’ processes for identifying
and addressing dual participation in SNAP prior to implementation of the NAC. The report described the
degree that the states were utilizing the PARIS match as part of those efforts. The observations showed a
wide variation, from no use of PARIS whatsoever (in Alabama and Georgia) to - in Florida - a systematic
process for utilizing PARIS data. Florida’s methods were described as follows:
Upon receipt of quarterly match data via PARIS, an automated process filters out cases in
which benefit overlap did not occur. The remaining cases, which require action of some
kind, are then divided between active and inactive. For the active cases, the system
automatically generates a letter to the client informing them that Florida has information
indicating they appear to be receiving SNAP in another state. The letter gives the client 10
days to produce verification of residency. A worker assigned to a Case Management Unit
works a report displaying the matches that resulted in a contact letter being delivered.
After 10 days, this worker checks to see if a document has been scanned in response to

Data collected at the Big Bang illustrates the prevalence of dual participation in Florida even with a
relatively robust use of PARIS data. The following statistics reflect collision volume just prior to NAC “go-

Furthermore, when dual participation did occur, it continued for several months, as evidenced by the
average and median spells of dual participation for individuals found to be receiving SNAP in Florida and
another pilot state:

Neither of these results are surprising given that PARIS operates under the pay and chase model and the
variety of data elements it utilizes to match individuals are significantly limited compared to the NAC.
Regardless, the data points to the potential advantages of the NAC compared to PARIS. Each of the
instances of dual participation represented above and the approximately $135/month
25
of SNAP
overpayments that accumulated every month duplicate benefits were issued could have been prevented
had the NAC been available AND utilized to its full potential by Florida and the other pilot states.
A passage from the 2001 GAO report summarizes the differences between the NAC and PARIS by
documenting state officials’ vision at that time:
“Officials from most states we spoke with said they would like a datasharing process that
could be used before benefits are providedthat is, a process that would allow state
caseworkers to check other states’ data to see if an applicant was already receiving
benefits elsewhere before the state approved an application for benefits. Such a process
would have to provide prompt responses (probably within 24 hours) to inquiries
something very different from the quarterly PARIS matches. One option for this process
includes a national database of clients receiving public assistance in any state. Such a
database would be maintained by the federal government and would consist of records
submitted and regularly updated by the states.”
Representatives from pilot states expressed hesitation to expend resources on PARIS given its limitations
in identifying dual participants effectively and the resulting work required for follow up. Those limitations
would continue to exist barring fundamental changes to PARIS changes that would likely exceed what
would reasonably be considered an expansion of that existing system.

PARIS.

What is the NAC’s Return on Investment?
Evaluation findings indicate that dual participation has in fact decreased in the pilot states, and that the
NAC gives states the capacity to prevent dual participation. This section addresses the question of
whether, and by how much, that decrease translates into savings in SNAP overpayment avoidance from
each pilot state given the manpower and technical resources required to participate and necessary to act
on the information the NAC provides. The analysis is conducted in three parts, each with multiple steps:
Monthly savings in SNAP overpayment avoidance (100% federal dollars)
Monthly costs in resources required to support the overpayment avoidance (all expenses eligible
for 50-50 federal/state SNAP administrative cost split)
Net Impact
Source data used is referenced in the narrative associated with the relevant step in the calculations.
Limitations/Assumptions
The estimates of cost savings should be considered conservative, for several reasons. First, the focus of
this analysis is solely on the prevention of dual participation; some additional savings is being realized
through earlier detection of ongoing dual participation when it does occur. Table 14 demonstrates the
impact of the NAC with respect to early detection. In this analysis, the decay rate
26
of dual participation
is calculated by comparing entries from December 2013 (before pilot) and December 2014 (during pilot),
and following these individuals for five months.

Table 14 illustrates that the NAC supports a faster resolution of dual participation when it does occur. For
example, in Louisiana, more than thirty percent of new instances of dual participation in December 2013
continued five months later. Once the NAC was in place, less than seven percent of the December 2014
entries were in dual participation status five months out.
26
Decay rate refers to decline in the percentage of clients who remain dual participants in the five succeeding
months following entry.

Other factors that have the effect of reducing the actual savings include the following:
A key variable in the calculation the difference in entries from the pre-pilot phase to the pilot -
uses only the Top 5 match code combinations. Depending on the state and its approach for
treatment of matches, some additional savings has been realized through the prevention of valid
“6+” matches, which accounted for 15 percent of all matches (excluding “SSN-only” matches)
from August 2014 May 2015.
The model is designed to represent the actual impact of the NAC through the end of pilot
operations, not the potential of the solution. Clearly, the pilot states (some more than others)
have room to improve their processes and should be able to increase their prevention rates over
time. The Recommendations section of this report identifies efforts that can support such
improvement.
The model assumes that when dual participation is prevented, the individual remains eligible in
their actual state of residence.
The savings does not include the recoupment of overpayments due to dual participation identified
at project “go-live.
Other methods used in the calculations that may result in under-counting the impact of the NAC are noted
in the narrative.
Savings Calculation
Step 1: Savings per month per instance of prevention
Each month that dual participation is prevented for an individual, a SNAP overpayment is avoided. The
value of this avoidance each month depends on the characteristics of the householdit could represent
an even distribution of the monthly SNAP allotment (in the case where all household members are dual
participants and the case would not have been opened), or a smaller percentage of the allotment (in the
case where an individual is removed but the case remains open). These factors are considered in
calculating the savings per month in each instance of prevention (see Appendix G for methodology relative
to percentage of allotment considered). Source data for this calculation is the Supplemental Big Bang
information provided by the pilot states.

Step 2: Savings per spell of avoided dual participation
Using data on individuals identified as dual participants at the Big Bang, the following method was
employed to establish the length of a typical “spell” of dual participation:
Identified eligibility date in each state
Selected the latest of the two dates to establish when overlapping eligibility began
Identified the next recertification date for the individual’s case in each state
Selected the soonest of the two recertification months, assuming that dual participation
would be identified and addressed at that time.
The number of months between the start of overlapping eligibility and the next recertification
month establishes the expected length of a dual participation spell.
The median number of months for each state’s spells are reflected below.

Step 3: Savings per month
The impact of the NAC on dual participation is quantified by a comparison of the number of entries per
month before and after implementation of the solution. The difference represents instances of dual
participation that would have occurred absent the NAC solution. The change in entries statistic (-263 for
Alabama below) was calculated using the average number of Top 5 match code entries over eight months
in the pre-pilot period (excluding September and November 2013) and comparing these to the average
number of entries over the last four months of the pilot.
In quantifying impact, it is vital to recognize that an entry is counted in both states involved in dual
participation, and that an individual will generally remain eligible in one of the two states. So, when
dual participation is prevented, only one state should receive “credit” for an avoided overpayment.
Accordingly, the reduction in dual participation entries must acknowledge that while dual participation is
being avoided, SNAP benefits will still be issued in the state in which the individual actually resides.
To avoid double-counting of savings, the change in entries between pre-pilot and pilot is multiplied by the
percentage of each state’s dual participants at the Big Bang that were that state’s “responsibility. In
other words, the “responsible state” determined eligibility and, upon authorization of SNAP benefits,
created the instance of dual participation. For example, Alabama was the 2
nd
authorizing state for 54.8%
of the dual participation identified at the Big Bang; therefore, applying that percentage to the reduction
in entries (263 x .548 = 144) provides an adjusted change that avoids crediting two states.

Step 4: Savings per month with redemption discount
Analysis of Big Bang Supplemental Data indicated that in approximately 12% of the dual participation
identified at the Big Bang, no SNAP benefits were redeemed in one of the two states involved in the month
prior. In this step, savings are reduced to reflect benefits that would not have been redeemed (88% were
redeemed in both states).

benefits estimated to actually have been redeemed had they been issued. The difference ($24,104)
represents SNAP benefits that were issued, but never redeemed.
Cost Calculation
Step 1: Costs associated with work effort as initiating state
This step captures resources expended when a match is received, including communication with the
matching state and time required to bring the issue to resolution. Note that it does not include “lag time”
between the initial contact with the matching state and the point at which action is taken. Source data
used in this step includes the state survey (staff time and wage) and MSH files (match volume).

Step 3: Other ongoing costs associated with NAC operations

addition, the monthly fee paid by states to LexisNexisbased on the number of individuals receiving SNAP
in each state are included here.

Without actual investment in new staff or equipment, ongoing monthly costs are dependent somewhat
on prioritization. Generally, states integrate technical work associated with the NAC into existing duties.
Step 4: Total costs
The three cost categories calculated in steps 1-3 are summed to generate a monthly ongoing cost for each
state. Ongoing costs vary and are affected by the volume of matches produced by the NAC, inquiries
received from other states, staffing costs, and the degree that processes are automated. Mississippi, on
the low end in all those areas, naturally has the lowest total costs per month as a result.

Net Impact
The impact of the NAC for each state over a year is calculated by subtracting costs from savings, and is
annualized by multiplying by 12. The calculation does not net out staff costs associated with non-NAC
matching processes, which continue as states receive inquiries resulting from an applicant’s self-
attestation or a PARIS match. In addition, while the savings are characterized as being realized by the

states, the SNAP overpayment avoidance that the NAC supports are 100 percent federally-funded

The pilot-wide net impact of the NAC totals more than $5.6 million. It is important to reiterate that this
estimate is conservative it focuses on the prevention of dual participation and not early (nearly
immediate) detection that the NAC can also support, assumes that an individual will remain eligible in one
of the two states involved, and is based only on the five match code combinations that are almost certain
to represent actual dual participation. Perhaps most importantly, though, the model reflects the business
processes in place during the pilot period; as these are perfected, the rate of prevention (and savings) is
expected to improve.
Start-up costs
The ongoing expenses reported by pilot states and used in the preceding cost savings analysis do not
include the one-time costs associated with initial start-up. Pilot states were also surveyed regarding the
resources expended prior to NAC operations, and results are presented in Table 16. Details of state
responses are included in Appendix F.
The question specific to NAC start-up costs instructed states to
include costs associated with programming, staff training, file
preparation, and planning. They were asked to exclude costs
specifically related to the evaluation, as those do not reflect what
other states could be expected to spend if the project is expanded
beyond the five consortium states.
One comment included in the survey from Florida noted that
expenditures would likely have been higher had it not been for other
systems-related priorities. Because the NAC project was started during the development of a new
Medicaid eligibility system to support the Affordable Care Act, the state was limited in its ability to create
a more integrated process with the existing SNAP eligibility system.
Potential Impact of Expansion
The cost/savings analysis estimates only the savings the NAC pilot states can expect if no other states join
the consortium. However, as NAC expansion has been explored, two additional questions related to its
potential impact have been posed:
1) How much would pilot states save if they matched with all 50 states; and
2) How much would the program as a whole save if all states participated?

Savings if pilot states matched with all fifty states
The five pilot states are contiguous but vary significantly in geography and population. They also
experience differing migration patterns from states across the country. Presumably, some pilot states will
experience more frequent dual participation with states outside the current consortium than others.
Data from PARIS matches, which are conducted with nearly all other states, was utilized to estimate the
percentage of all potential savings represented by the other four pilot states. This percentage was then
applied to the savings identified in the above analysis to estimate how nationwide implementation would
translate into savings for each pilot state.
Limitations
The use of PARIS data to extrapolate the prevalence of dual participation involving the pilot and non-pilot
states has several limitations. Optimally, a proxy would be available that allows for an “apples to apples
comparison. For example, if all states matched all their SNAP participants in PARIS and no other programs,
the distribution of matches could be reasonably expected to be similar for the NAC. Unfortunately, this
is not the case two primary factors impact the reliability of this method:
As noted in the Altarum study, some States have reduced the number of SSNs submitted to PARIS
by selecting only individuals that meet certain criteria, or selecting only individuals active in the
final month of the quarter for which the match is being conducted.
Not all states that do participate in PARIS submit data from the same programs. For example,
California may submit only their eligible SNAP population, while Illinois may submit both the SNAP
and Medicaid population. This results in a higher percentage of all matches occurring with Illinois
than if California also provided their Medicaid population.
These limitations are not insignificant. To provide at least a partial test of validity of this approach, the
distribution of PARIS matches within the pilot states only was compared to the breakdown of NAC matches
at the Big Bang.

With the exception of Mississippi, the distribution of PARIS matches and NAC matches in the months
analyzed were quite similar. This suggests that, at least within the pilot states, the relative
frequency/volume of NAC matches mirrors the distribution of PARIS matches.
Step 1: Percentage of all potential savings represented by the other four pilot states.
PARIS data from March 2013 (for AL, GA, LA, and MS) and November 2014 (FL) was used to calculate the
percentages in Step 1. In calculating the total number of PARIS matches, intra-state matches were
excluded, and the number of matches generated for each pilot states with the other consortium members
was divided by the total number of interstate matches.

Despite the limitations noted above, the percentages calculated in Step 1 align with anecdotal
assumptions:
Florida would have the highest percentage of matches with states outside the NAC pilot (81.1)
due to the large number of individuals traveling there from far outside the pilot areas for the
winter and/or tourism; and
Of the other four states, the one with the fewest non-NAC border states (Alabama, with one)
would have the lowest percentage of matches outside the NAC pilot area (47.5).
Step 2: Annual savings for each pilot state if the NAC were nationwide.
To calculate the annual net savings if the NAC were nationwide, the net savings for each state is divided
by the percentage of all savings represented by the NAC states only (calculated in Step 1).

Overall SNAP savings if NAC was expanded nationwide
The final component of the cost/savings analysis is to extrapolate the program-wide SNAP savings realized
if all states participated in the NAC. For this calculation, a range of savings is estimated based on the
percentage of each state’s total annual SNAP allotment comprised by the savings calculated above. The
same caveats noted above in calculating individual state savings if the NAC were nationwide apply to this
calculation.
Step 1: State savings as a percentage of all SNAP allotments in FY 14.
As noted throughout the report, the pilot states have achieved different degrees of success in utilizing the
NAC. This is underscored when the savings calculated in the previous step are compared to each state’s
total SNAP allotments.

calculated above ranging from .08% to .28% are applied to total allotments, the potential savings vary
from $53.8 to $193.4 million annually, and average more than $114 million. The significant variations
represented by the estimates in Table 18 underscore the uncertainty of the precise impact if the NAC
were expanded and utilized by all fifty states.

Recommendations
The five NAC pilot states have implemented the NAC in significantly differently ways; and have realized
different levels of success. States that have achieved superior outcomes provide a set of best practices
that should be considered as use of the NAC continues in the current states and as expansion beyond the
pilot is explored. Furthermore, the lessons learned by the five pilot states should be heeded by any state
using or intending to use the NAC. And, the evaluation has identified trends in and characteristics of
dual participation that can support decision-making going forward.
The recommendations below cover a range of areas and are grounded in both the quantitative analyses,
observations, and qualitative information included here and in previous reports. They are organized in
three general categories:
General Recommendations for All States;
Expansion-Specific Recommendations; and
Opportunities for Improvement.
General Recommendations for All States
Automate to the greatest extent possible. Both the statistical evidence and comments from pilot states
demonstrate the importance of automating NAC processes to the greatest extent possible. Options
related to automation include the following:
Integration of the NAC with the state’s SNAP eligibility system. This is a critical component. Statistics
cited previously relative to the overall prevalence of dual participation indicate that matches will be
generated by the NAC on only a small percentage of applications and new household members. Given
the need to streamline eligibility processes and achieve business process efficiencies, caseworkers
should not be asked to check the NAC portal on every application they process and every person they
add to a case. Instead, NAC data should be integrated into the existing workflow, flagging a
caseworker to take additional steps only in the event a match is produced.
Use of web services to optimize real-time automation. Web services, which provides states with a
real-time link to the NAC, provides a “best of both worlds” model, in which the NAC is queried in near
real-time in a manner similar to a manual portal query, with the added advantage of limiting
caseworker intervention to only those instances in which a match is generated. For example, if a
caseworker needs to process as application on the same day the application is registered, the web
services concept allows for sending and receiving information from the NAC that same day. In a batch
process model, the return information would not be returned until the following day.
Automation of emails to the matching state. The level of certainty for match code combinations 1-5
is such that additional worker investigation regarding its validity is not necessary. Accordingly, an
automated email to the matching state eliminates the need for a caseworker to draft and send the
email and ensures that contact is made. Furthermore, the email format can be standardized with all
necessary information for the matching state to take appropriate action upon receipt.
System edits that require resolution of a match before authorization. To further ensure that staff act
on matches that may impact eligibility, system edits can be programmed that force the user to enter
a resolution code prior to authorization of benefits. These codes also have potential to be used to
track outcomes if the resolution options include an indicator of whether the match was determined
as valid or not.

Establish processes for utilizing the NAC when individuals are added to an open SNAP case. SNAP
eligibility interviews conducted when a new application is processed include standard questions regarding
SNAP receipt in another state. And, the application itself includes this question as well. However, the
same procedures may not be followed when a new individual is added to an existing SNAP case for
instance, an application is not required when adding a new household member. And, the business
processes in place in Georgia and Florida suggest that the addition of new household members is likely
contributing to those states’ lower rates of prevention success.
Although data collection for the evaluation did not specifically address the percentage of individuals
whose dual participation began when they were added to an existing case, a similar scenario was
identified that provides some insight. This analysis calculates the percentage of dual participants (at the
Big Bang) who were not part of households in which all members were also dual participants.

When 100% of SNAP household members are active in two states, it is presumed that the household
moved as a unit from state-to-state and standard application processes were conducted. However, if all
household members are not dual participants which was the case for almost half (47%) of the individuals
in this analysis - it is more likely that the situation was different. While not a definitive indicator of the
circumstances involving an individual’s approval for SNAP in a second state, these statistics suggest that
a significant percentage of dual participation occurs when a new member is added to an existing case.
Accordingly, states should institute a robust process for using the NAC in those situations. The web
services model described above would be optimal; in the absence of that solution, worker access to the
NAC portal is an alternative to be considered.
29
Data sources: Big Bang administrative data (# of household members who were dual participants) and information
collected by pilot states (SNAP household size). Also, note that household with one member are included in
calculating the number of cases in which all household members are dual participants.

Treat Social Security Number-only” matches differently.
Matches are characterized as SSN only” if the Social Security Number is the only data element that
matches between eligible SNAP participantsname, date of birth, and all other demographic information
are dissimilar. Table 20 captures the state-determined explanations for the Big Bang matches that fell into
this category.

A data entry error typically means that a caseworker transposed one digit when entering a SSN into the
state’s eligibility system; if the SSN has been verified correct, documentation provided by the individual
or head of household, such as a Social Security Card, confirmed the number entered in the state’s
eligibility system as belonging to that individual.
As a lesson learned for future NAC states, an internal review of SSN-only matches to confirm that a data
entry error was not the cause is advised prior to making contact with the other state involved (or the
client). In the event both states confirm the accuracy of the SSN, further investigation will be necessary.
In a few isolated cases, states discovered that the Social Security Administration had issued identical SSNs
to two different people.
Establish processes for addressing dual participation when prevention is not possible or
unsuccessful. For reasons of access or process failure, dual participation will still occur even with the
availability of the NAC. Although prevention of dual participation is the primary goal of the Clearinghouse,
it also provides information necessary to shorten spells of dual participation when they do occur.
Designate a task force to act on dual participation. Because an overpayment has occurred in these
situations, it may be efficient to integrate the task into a centralized state claims/investigations unit
to limit duplication of efforts.
Automate MSH reports for delivery to entity responsible for action. By having the MSH report be
automatically generated as an email/report to the user group that will be following up, it helps remind
the worker of the match instead of them having to manually run the report.
Expansion-Specific Recommendations
In the event additional states join the consortium and begin submitting contributory files to the NAC,
several lessons from project start-up and the pilot’s Big Bang should be applied. In addition, the increased
volume of work associated with new states taking part in the NAC calls for a level of uniformity that is not
as essential when only five states are involved.
Develop separate processes for the initial match and ongoing operations. The best practices
described above regarding automation will support effective prevention of dual participation as new
states are added. However, the addition of each new state will be accompanied by an initial match of dual
participants a “mini-bang.” These events will impact not only the new NAC state/s, but those already
participating. The following approaches to addressing subsequent initial collisions are recommended:
National Accuracy Clearinghouse (NAC) Evaluation | Final Report
October 2015
42
Establish a task force to work initial collisions. The volume of time and effort required to address
existing dual participation is considerable, and when the NAC is implemented caseworkers’ focus
should be on prevention. Both the newly-entering and existing NAC states should designate a specific
team staffed appropriately to handle initial collisions. This supports tracking of progress, more
consistent communication with other states, and a clearer structure for identifying the need for
establishment of overpayment claims.
Make preparations for staff to establish overpayment claims. The first time contributory data from
a new NAC state is submitted for matching, a significant number of collisions is to be expected. And,
given that these collisions will represent possible overpayments, capacity of staff responsible for
establishing claims will be strained.
Table 21 documents the volume, types, and value of the claims established on cases in which an
individual/s was identified as a dual participant at the Big Bang.

Only send automated letters initially to high-confidence match combos. Approximately 85 percent
of matches (excluding “SSN-only) are comprised of high-confidence match code combinationsin
those instances, a contact letter to the head of household notifying them of apparent dual
participation is appropriate. However, for the other 15 percent of matches, states should conduct a
review of the information provided prior to making contact with the client
31
.
Conduct comprehensive front line staff training. Effective training of front line staff is essential to
effective project implementation. Resources should be dedicated to the delivery of training, and the
materials developed should give caseworkers real-world examples and/or hand-on experience in the
approach the state will use to operationalize the tool and communicate with other states. In addition,
training should provide background on the NAC and its potential benefits to promote buy-in from staff
that may view it as just another task to add to their many responsibilities.
Recognize and address connectivity and IP address issues as early as possible. Some pilot states
experienced problems with access to the NAC because they were blocked by the NAC’s firewall. In
November 2014, some county offices in Alabama were unable to access the NAC portal due to a network
translation change; Georgia’s efforts were hampered due to difficulty in collecting all the public IP
addresses used for system access across the state; and, Florida reported problems related to the large
number of IP addresses utilized by home-based caseworkers. While these issues were rectified, states

43
preparing to join the consortium would be well-served to begin identification of all home-based staff and
take other steps to identify public IP addresses as early as possible to prevent similar barriers to NAC
access.
Implement business process standardizations. While it is important to allow states the flexibility to
develop their own procedures with respect to some aspects of the NAC, there is additional standardization
that could support effective use of the tool, particularly if additional states join the project.
Consistent treatment of match code combinations. States have implemented similar, but not
identical, criteria for the treatment of matches depending on their strength. For consistency of actions
across the program and clear communication between states, a standard definition of the matches
considered to be valid without further investigation is recommended.
Timely submission of contributory files. Once a month, the daily contributory files submitted by the
states include the active SNAP recipients for the next recurring month. During the pilot there was
inconsistency across states with regard to the timing of this submission. In some cases, late submission
of these files resulted in missed opportunities to prevent dual participation. The date of this recurring
file may be dependent on factors outside the control of staff responsible for NAC implementation;
however, to the extent possible, a consistent date of submission, preferably as early as possible prior
to the benefit month in question, should be established.
Common naming conventions for email addresses used for interstate communication. (e.g.
[email protected]). If additional states are added to the NAC, each state will also be establishing a mailbox
for NAC-related communication. A common convention including the “NAC” and the state name
would simplify interstate emails.
Standard protocols for transmission of personally identifiable information (PII). States were not
consistent in the conventions used for transmission of client information when communicating via
email about a NAC match or collision. A standard process describing the security protocols should be
established for states exchanging PII in NAC-related communications.
Opportunities for Improvement
Apart from the best practices identified that will help current and future NAC states, some areas of
improvement are apparent that, if addressed, could optimize use of the NAC.
Reconsider the business process change to require notification of closure/removal. Originally, the
common business processes included a rule designed to limit the frequency of communication between
the two states involved in a match generated by the NAC. This rule dictated that states would assume
communication delivered by the initiating state prior to the 15th of a month would result in action being
taken by the matching state in time to impact the next month’s SNAP benefits. And, because this
assumption was in place, no return email from the matching state would be needed.
However, pilot states identified examples in which the matching state did not take action timely it was
not always safe to assume that an individual would be removed from a case or a case would be closed
prior to benefit issuance for the following month. This resulted in dual participation for the individual in
question. Following discussion, the pilot states decided that action in the initiating state would not be
taken under the assumption that the matching state had acted timely, and the business rules were
modified.
Under the new rules, an email from the matching state must be provided to the initiating state confirming
the action taken and the effective date, regardless of the date the request was made by the initiating
National Accuracy Clearinghouse (NAC) Evaluation | Final Report
October 2015
44
state. While this modification is understandable given states’ early experiences, the policy should be
reviewed by NAC states on a regular basis to determine if the original concept could be re-instituted.
Consider wider use of Activity Type 3 (passive matches). States receive this information when an
individual who is active in their state (the matching state) has been submitted to the NAC by another
state, presumably because an application is being submitted there. Typically, pilot states have waited for
an email from the initiating state to take action on their case/individual. However, states should explore
using the passive matches to inquire about the household situation, as it may allow action to be taken
more timely than it would be otherwise.
For example, if Alabama received an Activity Type 3 match showing that an individual active there has
been queried by Florida, this indicates that Florida had a reason to inquire about the individual’s eligibility.
Typically, Alabama would wait and for contact from Florida asking for action to be taken. However, the
receipt of the Activity Type 3 match allows Alabama to proactively inquire about the individual’s residence
there. This gives the state a better opportunity to meet the two-day turnaround standard documented
in the common business rules.
_______________________
The overarching conclusions of the National Accuracy Clearinghouse (NAC) Evaluation may be summarized
as follows:
1. The NAC has supported a decrease in dual SNAP participation;
2. When implemented using the best practices outlined above the NAC supports the prevention of
dual participation in a manner and scope not possible with the resources previously available;
and
3. Despite the relatively infrequent occurrence of dual participation, the prevention made possible
by the NAC translates into significant SNAP overpayment avoidance.
The findings suggest serious consideration should be given to expansion of the project.

Glossary
Active Dual Participation Caseload The number of dual participants in a state during a given month.
During the pilot period, calculated by adding “Entries and “Continuations (see below).
Big Bang The process of identifying and acting on all apparent instances of current dual participation
identified at the point the NAC database became available to the pilot states in June 2014. The term was
coined as a way to differentiate activities associated with the initial implementation of the NAC from the
ongoing use of the tool.
Collision An instance in which dual participationreceipt of SNAP or D-SNAP in two or more states in the
same month - appears to have already occurred per the NAC. The term refers to both individuals identified
at the “Big Bang” and those coded as Activity Type 4” on the Match Search History (MSH) file (see
definitions below).
Continuations Collisions that are present in both the target month and were present in the previous
month.
Entries Collisions that are present in the target month but were not present in the previous month.
Exits Collisions that were present in the previous month but not the target month
LexID The NAC leverages the LexisNexis LexIDSM technology to provide identity resolution by comparing
input information provided by participating states across billions of unique public records. These public
records, linked together using the LexID, provide context to an identity, such as how it has changed over
time (moving addresses, name changes, marriage/divorce, etc.) or where input information is missing or
incorrect. Through identity analytics, LexisNexis is able to resolve input information to a single individual
with an high degree of accuracy. The LexID is a unique, 12-digit identifier assigned after a successful
identity resolution.
Match An instance in which a state identifies via the NAC that an individual is already receiving SNAP or
D-SNAP benefits in another state; generally in the context of dual participation prevention (prior to
approval of benefits in a second state). When states “work” a match, the following designations are used:
Initiating StateRefers to the state in which the individual is applying and has not yet been
approved for SNAP.
Matching StateRefers to the state in which the individual is already receiving SNAP benefits.
Match Search History (MSH) file a daily file created for each of the five pilot states and comprised of
four “Activity Types,” documenting the previous days’ NAC activity for four types of actions:
1. Single (Activity Type 1): a record of requests (and resulting matches if applicable) for match
information made by states via NAC portal queries or via state eligibility systems connected to
the NAC by web service
2. Batch (Activity Type 2): a record of requests (and resulting matches if applicable) for match
information made via batch process
3. Passive (Activity Type 3): a notification informing a “Matching“ state that an “Initiating” state
conducted a search that generated a match
National Accuracy Clearinghouse (NAC) Evaluation | Final Report

4. Build-Time Collisions (Activity Type 4): A record of new collisions
PARIS Public Assistance Reporting Information System. PARIS is the data matching system administered
by the Administration for Children and Families (ACF) within the Department of Health and Human
Services (HHS). States submit data to PARIS (voluntarily) on active participants in several programs,
including SNAP, on a quarterly basis.
Spell Refers to a period of time during which dual participation occurred. For example, for someone
who is eligible in both Alabama and Florida from January to April of 2015, a four month spell of dual
participation occurred.

B Methodology Percentage of Matches that Became Collisions
For each month that is part of this analysis, two separate files were created using information found in
the daily Match Search History (MSH) files:
Match fileAll MSH Activity Type 1 matches (generated through portal and web services queries)
and Activity Type 2 matches (generated through the nightly batch process) comprising one
calendar month (the target month) were compiled.
o Duplicate matches were removed using Search SSN as the primary identifier. This was
necessary to prevent double-counting of individuals identified through both a batch
match and a portal query.
Collision file All Activity Type 4 collisions (generated by the nightly NAC database build) on MSH
files were compiled for a four month period including the target month, the month prior, and the
two following months (X, X-1, X+1, X+2, respectively). Additional months of collision files were
utilized because a collision could be prevented for past or future benefits months.
o The MSH files selected for each month ranged from the 2nd day of the month until the
1st day of the following month. For example, to create the collision file for March, MSH
files from 03/02/201504/01/2015 were utilized, because collisions do not appear until
the day following when benefits were authorized in the second approving state.
The match and collisions data were then compared to determine if an individual on the match file also
appeared as a collision in any of the four months (X, X-1, X+1, X+2). If so, a “preventable collision
occurred. If an individual appeared in more than one of the four months, only one instance of a
preventable collision was counted.

D Process for Using the NAC for Prevention of Dual Participation as of May 31, 2015
State
Non-expedited applications
Expedited applications requiring
same-day processing
32
Adding individual to
existing case
Alabama
All applicants are submitted to the NAC via the Match Request File (MRF)
on the night of application registration.
The Match Request Response (MRR) that is returned overnight is imported
to the state’s eligibility system (The Online Application and Case
Information System, or “OACIS) to alert the caseworker conducting the
interview of the NAC hit. Caseworkers investigate and determine if email
to other state is warranted.
In addition to emailing the other state, many caseworkers also ask the
client to provide written proof of closure
33
.
Action on application is pended until email from other state is received or
applicant provides documentation of closure in other state.
County staff query
34
NAC portal
prior to approval of the
application.
Applicant’s status is verified prior
to the approval of the application
if possible; if ID has been verified,
postponed verification policy is
utilized in the rare occasion that
match appears to be accurate but
applicant is insistent that they
aren’t active in other state.
OACIS reminds worker to
query NAC if taking same-
day action to add
individual (this process
occurs in majority of
instances); if not
authorizing same day,
individual is submitted to
NAC via overnight batch.
Florida
All applicants are submitted to the NAC via the MRF on the night of
application registration.
Workers are notified of any NAC matches returned via the MRR via a
message (“Customer is receiving benefits in another state”) on the Work
Item Detail page the next morning before 7 AM.
No additional information is provided to the worker in the message. When
the alert is received on the Work Item Detail page, staff must complete a
search on the NAC portal for all individuals on the application prior to
SNAP authorization for the current month.
Staff has flexibility to either follow the common business rules (i.e. email
the matching state) AND/OR ask applicant for a closure letter.
Applicants receive a letter notifying them of the window they have to call
for their interview (which may be with a clerk or caseworker); this letter
can include the request for proof of closure as part of the list of
information needed to determine eligibility.
There is no process in place to
check the NAC if disposition on an
application is taken prior to
processing of the overnight batch.
New individuals added to
active cases are sent
through the overnight
batch; same process as
non-expedited application
occurs.
32
Overnight batch process does not support dual participation prevention when state needs to take action on case the day application is registered.
33
At least one state (Florida) has reported an apparent increase in clients requesting closure through the online “my account,” citing the reason as applying in
another state.
34
Because states provide updates on active SNAP recipients to the NAC database on a nightly basis, this query provides near real-time information on the
individual’s status in the other pilot states.

Georgia
All applicants are submitted to the NAC via batch on the night of
application registration.
A report is generated from the return file of matched individuals and is worked
by a team of three claims managers. Team members send the contact to the
email address for the other state. When the response is returned, the claims
manager documents the hit information and that the match has been
addressed directly in the case record. The process is designed to work as
follows:
The initial contact with the other state should go out within 24 hours of
receipt and the return response is due within 48 hours of notification.
The expectation is that the documentation be in the case no later than 5
days after being notified of the hit.
With the current process in place in Georgia for applicants, cases are registered
and assigned to workers for an interview. Expedited cases are interviewed
usually no later than the 5th day following application. In this process, it is
expected that expedited cases may be missed for one month but most non-
expedited cases will be documented and the caseworker aware of the match
before the initial month’s benefits are issued. Caseworkers do not have access
to the portal. A fourth worker was added to the process at the end of
December 2014 to further ensure that caseworkers are notified and cases are
documented timely.
GA is building a new eligibility system which will include an indicator generated
by a NAC match, but implementation is at least one year away (mid to late
2016).
Caseworkers act on expedited
cases to meet timeliness rules;
same process occurs as for non-
expedited applicants who
generate matches (i.e. caseworker
typically does not become aware
of the match until after benefits
have been authorized).
Individuals added to an
active case are submitted
through the nightly batch;

non-expedited applicants

(i.e. caseworker typically

the match until after

authorized).
Louisiana
All applicants are submitted to the NAC via web service on the night of
application registration.
Matches are loaded daily to Clearance Summary screen (outside of the
eligibility system) for review/action by caseworkers in the Parishes.
Caseworkers receive all pertinent data from the Clearance Summary
screen and do not have access to the NAC via the portal. It is the
responsibility of caseworkers to identify if the match is qualified per state
business rules.
Limited # of staff (Regional
Program Consultants) have portal
access to conduct searches when
an expedited application is to be
approved before the overnight
web service process runs.
Caseworkers forward relevant
information to their supervisor
who requests that the query be
conducted.

Mississippi
The overnight batch process was utilized from 6/1/2014 through
11/30/2014; on 12/1/2014, Web Services was implemented statewide
which provides for a real-time response (MRR) to each search request
(MRF).
Response received from NAC is integrated into the eligibility system and is
populated on a screen that the worker is directed to if there is a match.
o System edits prevent authorization of the case if this screen has
not been handled by the worker.
For “level one matches (see discussion of match codes) the system
generates an email to the matching state/s where a match has been found,
requesting response within 48 hours per business rules.
o Return emails from other state are directed to a centralized unit
that in turn notifies the caseworker of necessary action.
For “level two” matches, caseworkers evaluate the information and have
discretion regarding whether an email to the other state is needed.
On 10/31/14, MS modified the email subject line to include the MS State
Code and Full Service Office (County) to improve email identification when
received from Matching State/s; modified the body of the email to remove
the Matching State/s' individual Client ID and DOB to prevent any possible
identity theft when emailed; modified body of email to match revised NAC
business language; modified emails to be grouped as one email for all
matching individuals by the Matching State/s Case ID rather than
individual emails each day which improves the Matching State/s' email
processing.
Same process as Non-expedited
applications with one exception:
The Match State/s will be
contacted via phone, if necessary,
to ensure timely processing of the
expedited application.
Same process as new
application.
35
Louisiana’s processes are designed so as not to burden workers with unproductive matches that occur when newborns who have not yet been issued a SSN
are added to a case. Not only is dual participation extremely unlikely among this population, but searches conducted without a SSN do not meet the threshold
the state has established for a valid match.

E Matching State Process for Responding to Request from Initiating State as of May 31, 2015
State
Process
Alabama
State office forwards the email to the applicable county. Supervisor or workers in the county sends email to other state informing them of the
action taken and the effective date in Alabama. The county is responsible for the contact to the other state. The county does not routinely cc the
state office.
Florida
A NAC email has been set up for all inquiries from other states. This email is directed to the Quality Control unit who will take action and respond to
the other state.
I. If match includes all household members of the case in FL, worker closes case effective the next possible month.
II. If match does not include all members of the case in FL, the worker will remove the member and notify the other state that the individual
has been removed with effective date.
Georgia
Emails from the Initiating State are currently received by 2 claims staff. Responses are sent back to the initiating state within the 48 hour deadline
when possible.
Louisiana
Emails from the Initiating State are received by the Inquiry Services Section; personnel in that unit check to see who is responsible for the case and
forward it to the applicable parish.
Mississippi
A centralized unit within the state office (3-4 persons) receives the emails and forwards them to the applicable county for action.
