1. Introduction The United States Department of Agriculture (USDA) Food and Nutrition Service’s (FNS) mission is to increase food security and reduce hunger for children and low-income households through access to food, a healthful diet, and nutrition education in a way that supports American agriculture and inspires public confidence.
FNS administers the USDA nutrition assistance programs, including the cornerstone Supplemental Nutrition Assistance Program (SNAP). FNS administers SNAP nationally, while the State and local human services agencies operate the program locally. The Agriculture Improvement Act of 2018, commonly known as the 2018 Farm Bill, reauthorized SNAP through Fiscal Year (FY) 2023.
Millions of people rely on SNAP to purchase food at authorized grocery stores, convenience stores, farmers' markets, and co-op food programs. Some participants cycle on and off the program as their eligibility status changes throughout the year. Tracking participants and their participation status over time is not currently viable for many States, making it difficult to measure program impacts. Thus, Congress set forth a legislative measure in the 2018 Farm Bill will enables research of participants over time and across State lines, also known as the SNAP Longitudinal Data Project (SNAP LDP).
1.1. SNAP Longitudinal Data Project at a Glance
The SNAP LDP aims to enable research on participation in and the operation of SNAP, including duration of participation in the Program over time and across State lines. Section 17(n) of the Food and Nutrition Act of 2008, as amended in December 2022, allows States the option to participate in the SNAP LDP. Key aspects of SNAP LDP include:
• Provides $20 million in grant funding for FY 2021 and $5 million for each FY thereafter, for State agencies interested in establishing longitudinal research databases with eligibility, benefit, and demographic information about SNAP households and individual SNAP participants;
• Requires unique identifiers to protect individual privacy and to enable comparison of participation data across States and over time as part of a national longitudinal database;
• Requests SNAP data elements from States, if available, including demographic characteristics, income and financial resources, employment status, household circumstances, and monthly allotment amounts; and
• Requests data from other State sources, if available, including: earning and employment data, health insurance program data, and participation in other State programs.
2. Purpose This document provides an overview of the SNAP LDP, as well as guidelines and parameters for States interested in participating, including:
• How to opt into participation,
• How to meet security requirements,
• How to transmit data securely, and
• How to apply for grant funding.
FNS will update the SNAP LDP Parameters for Participation (PFP) periodically to ensure States have current information. This document is the second edition of the PFP. The table below documents the editions and the date of the changes.

Version 2.0 04/27/2023
3. Overview The overarching goal of the SNAP LDP is to enable research on participation in and the operation of SNAP, specifically over time (e.g., duration) and across State lines. FNS has established an inter-agency agreement (IAA) with the Census Bureau to reduce the burden on States who choose to participate in the SNAP LDP and may already be transmitting other SNAP data with the Census Bureau. The Census Bureau will receive State-submitted SNAP data, assign a unique identifier for individuals, de-identify data, and create a secure longitudinal database. Participating States, at a minimum, will securely transmit the required data elements, if available, to the Census Bureau to be available for longitudinal research.
Any research conducted using the national SNAP LDP data must meet the following requirements:
• Aligns with provisions set forth in Section 17(n) of the Food and Nutrition Act of 2008, as amended in December 2022,
• Adheres to the Census Bureau and State requirements as specified in the State agreements, to include the project description, and
• Meets the research goals and objectives of the SNAP LDP as determined by approval from the Census Bureau and FNS
In addition, FNS recognizes States may benefit from performing their own State-specific longitudinal research. Thus, agencies that elect to transmit data to the Census Bureau may request grant funding to establish or enhance individual State longitudinal databases. States should not make changes to their existing eligibility systems to ensure the integrity of the data and the eligibility determination process. The longitudinal database should be a separate database.
Grant funding is available for State agencies interested in participating in the SNAP LDP. Additional information about the application and types of projects eligible for funding are in Section 4, 4.1.
Grant Funding.
3.1 Collaboration with the Census Bureau
To reduce the burden on States and protect personally identifiable information (PII), FNS is collaborating with the Census Bureau to leverage its existing process of establishing memoranda of understandings (MOUs) and securely transferring data from the States to the Census Bureau.
Fundamental to the SNAP LDP is the ability to link the same person across multiple administrative files, while de-identifying the data so that personal information is not available. The Census Bureau’s approach to this applies the following security measures:
• Prior to incorporating State data into the Federal longitudinal database, the Census Bureau’s Person Identification Validation System (PVS) identifies a unique person across State datasets and within State datasets. Then a unique person identifier, also called the protected identification key (PIK), is assigned and all PII is removed. Once assigned, the PIK serves as a unique identifier across all files processed using the PVS.
• All data incorporated into the Federal longitudinal database is de-identified and no PII remains. No one—including the Census Bureau employees—can identify a participant. The de-identified data is NOT provided back to States but remains available for research as described below.
• Data may only be used for the purposes agreed upon by each State in the MOU. The Census Bureau and FNS review the research requests to ensure they meet the requirements of Section 17(n) of the Food and Nutrition Act of 2008, as amended in December 2022.
• Before researchers can publish any tabulations using the data, the Census Bureau reviews the proposed release to ensure the confidentiality of individuals in the data is protected.
https://www.google.com/url?sa=i&url=https://www.nrcs.usda.gov/wps/portal/nrcs/detail/ks/about/?cid%3Dnrcseprd1417224&psig=AOvVaw2LVcLTdlXZDjvIf5q_gmN0&ust=1586534670562000&source=images&cd=vfe&ved=0CAIQjRxqFwoTCJisu-jc2-gCFQAAAAAdAAAAABAD https://www.google.com/url?sa=i&url=https://en.wikipedia.org/wiki/Supplemental_Nutrition_Assistance_Program&psig=AOvVaw03NCJQpQPTtLnsWe-5ld9v&ust=1586534740049000&source=images&cd=vfe&ved=0CAIQjRxqFwoTCJjti9Xc2-gCFQAAAAAdAAAAABAI
• States with an existing MOU, as part of other research projects, have the option to update their MOU with an amendment to easily opt into the SNAP LDP and specify SNAP LDP as an allowable use for the data. Participating States without an existing MOU will establish a new MOU with the Census Bureau. Additional information on this process is below in Section 4,
4.1.3. How to Participate. States will coordinate with the Census Bureau for all aspects of the data transfer process and establishing an MOU. States will coordinate with FNS for all aspects of SNAP LDP grants administration, including changes to planned implementation and research objectives and proposals.
3.2 Conducting Research
Section 11(e)(8)(A) of the [Food and Nutrition] Act (7 U.S.C. 2020(e)(8)(A)) limits the use of SNAP recipient information to those directly connected with the administration or enforcement of the provisions of the Act. The SNAP LDP establishes a set of standard and optional data elements that participating States may submit to enable longitudinal research on SNAP participation, including duration. Additionally, FNS highly encourages States to work towards the optional SNAP Gold Standard format in their SNAP LDP data submissions, The SNAP Gold Standard is a method for standardizing data across States to facilitate ease and efficiency of research and longitudinal measurement. More about the SNAP Gold Standard is located in Section 4, 4.4. SNAP Gold Standard.
One of the State benefits of developing a longitudinal dataset is the ability to conduct internal research on the SNAP recipient population. States can securely join recipient data with other State-maintained datasets to analyze program participation over time. Potential research project ideas suggested by States in the past have included, but are not limited to:
• Leveraging longitudinal SNAP participation data to develop pilot projects intended to reduce program churn,
• Joining longitudinal SNAP participation data with Retailer EBT data to allow a State to understand benefits redemption patterns, particularly across different income levels, counties or zip codes, and in response to the expansion of online purchasing during the Public Health Emergency,
• Combining longitudinal SNAP participation data with TANF, WIC, Medicaid, and Unemployment data to look at cross-program utilization over time,
• Aggregating longitudinal SNAP participation data with early learning, post-secondary, and workforce data to gain a more holistic view of recipients’ life circumstances.
Researchers can apply to conduct research projects using SNAP longitudinal data from multiple States. Researchers must have Special Sworn Status (SSS) and a research proposal approved by the Census Bureau and FNS. SSS ensures additional protection around the data and those who achieve SSS must adhere to robust ethics, confidentiality, and privacy protection procedures. Researchers who meet this criterion may access the data at a Federal Statistical Research Data Center (FSRDC).
Upon receiving the required approvals, researchers may use the Federal longitudinal dataset to conduct research on participation in and the operation of SNAP, including duration of participation in the Program and 'movement across State lines. The following scenarios are examples of potential research topics for this data:
• Households that exit and re-enter the program within a short period of time, referred to by FNS as churn.
• Household members who over time leave their original household and join a new household (e.g., a minor reaches adult age and becomes a single household SNAP recipient).
• Household members who participate in SNAP in one State, leave SNAP, and then later re-apply in a new State.
https://www.google.com/url?sa=i&url=https://www.nrcs.usda.gov/wps/portal/nrcs/detail/ks/about/?cid%3Dnrcseprd1417224&psig=AOvVaw2LVcLTdlXZDjvIf5q_gmN0&ust=1586534670562000&source=images&cd=vfe&ved=0CAIQjRxqFwoTCJisu-jc2-gCFQAAAAAdAAAAABAD https://www.google.com/url?sa=i&url=https://en.wikipedia.org/wiki/Supplemental_Nutrition_Assistance_Program&psig=AOvVaw03NCJQpQPTtLnsWe-5ld9v&ust=1586534740049000&source=images&cd=vfe&ved=0CAIQjRxqFwoTCJjti9Xc2-gCFQAAAAAdAAAAABAI
States can conduct research internally, using SNAP LDP and other State-maintained datasets, so long as the data is housed securely within a State-maintained database and the State seeks FNS approval prior to publicly releasing any findings from the research. States that wish to conduct research using Federal or other States’ data in addition to their own must seek SSS, receive formal research project approval from the Census Bureau and the State whose data is requested, where applicable, and work with the data solely within a FSRDC. For more information on how to obtain access for researchers, please contact the State’s local FSRDC administrator or visit the following sites:
• https://www.census.gov/about/adrm/fsrdc/contact.html
• https://www.census.gov/about/adrm/fsrdc/locations.html
4. Parameters for Participation Participation in the SNAP LDP is optional. The Census Bureau and FNS will leverage and modify existing MOUs, when available, for States that are interested in participating. States that do not yet have an agreement in place can establish a new MOU. Each MOU contains the research project descriptions that the State and the Census Bureau agree upon and the allowable uses of data for each project. State-provided data can only be used for the projects listed within the State’s MOU. These research projects are independent of one another.
When considering participation in the SNAP LDP, interested States should conduct an informal cost-benefit analysis to determine (1) necessary costs required for this project to support grant funding requests, and (2) the benefits of participation. States should also consider the following:
• Feasibility to meet requirements set forth in Section 17(n) of the Food and Nutrition Act of 2008, as amended in December 2022,
• Sustainability of the project,
• Technology requirements,
• Staff necessary to support the project, and
• Potential data standardizations or transformations that would be required.
4.1 Grant Funding
Each of the 53 agencies that administer SNAP are eligible to apply for grants to support their participation in the SNAP LDP. FNS will award grants on a competitive basis to the agencies that submit proposals. Each agency can request a grant funding amount no greater than $2.25 million over a multiple year period of performance. However, the amount of awarded funding is at the discretion of FNS. Proposed grant projects may have a period of performance of up to four years. Proposals must include detailed project plans and budget summary information that includes the allocation of funds for each year. Additionally, State data sharing agreements with the Census Bureau may be longer than the period of performance for the grant project. This enables long-term sustainability in support of the SNAP LDP.
While FNS will review all proposals, grant requests proposing any modification of State eligibility systems related to the SNAP LDP are not allowed. The State Systems Office is responsible for the review and approval of any proposed changes to State eligibility systems. Since SNAP eligibility system data is often intermingled with other data in a data warehouse or integrated system that is used by multiple programs, the risk of the data becoming inadvertently over-written, shared, re-used, converted, or otherwise “cross-contaminated” by being too tightly coupled to the eligibility system or its primary data management environment is high. Thus, FNS strongly recommends that any technologies and databases to support the SNAP LDP are separated from the existing eligibility system to ensure traceability of funds, privacy, and data security.

4.1.1 Types of Applications Considered
All projects must support the overall goal of the SNAP LDP, which is to enable longitudinal research on participation in and the operation of SNAP over time and across State lines.
During the application process, State agencies should consider the key SNAP LDP objectives in the table below.
# Objectives
1 Securely transmit and/or enable the secure transmission of the monthly required data elements for the SNAP LDP with FNS/Census Bureau on an annual basis
2 Securely transmit and/or enable the secure transmission of the monthly optional data elements for the SNAP LDP with FNS/Census Bureau on an annual basis
3 Improve the evaluation of SNAP data across State lines by progressing toward the Gold Standard1 data format
4 Enable SNAP longitudinal research
Examples of potential project ideas considered eligible are listed below. These are ideas only and applicants should identify projects that best fit the needs of the State and that can be successfully implemented in the Period of Performance (e.g., summer 2023 to summer 2027).
• Define data definitions.
• Add a calculated data element without modification to the eligibility system.
• Add a data element that is external to the eligibility system.
• Build/procure a database or longitudinal database.
• Improve technology implementation, data management, and/or business processes.
• Develop a cross-agency sharing agreement.
• Implement additional extract, transform, and load (ETL) tools for data preparation.
• Implement analysis tool or software to support SNAP data analysis as it relates to the SNAP
LDP objectives.
• Improve data management processes (e.g., storage, security, standardization, transmission, and extraction).
• Improve data standardization to align to the SNAP Gold Standard, as defined in Appendix C:
SNAP Gold Standard and NIEM.
• Develop Extract Transfer Load (ETL) queries to facilitate data transmission with the Census
Bureau.
FNS highly encourages States to implement the SNAP Gold Standard format for data transmitted under SNAP LDP. Additionally, FNS encourages States to transmit data using the National Information Exchange Model (NIEM), where possible. States can request grant funding to accommodate participation in both the SNAP Gold Standard and to submit data using NIEM. Additional information on the SNAP Gold Standard and NIEM submission are in Appendix C: SNAP Gold Standard and
NIEM.
Furthermore, applicants may submit funding requests to support State-specific longitudinal research needs as an allowable cost so long as they have established an MOU to transmit SNAP LDP data with FNS and the Census Bureau. There are several potential uses for SNAP longitudinal data, particularly related to the ability to link SNAP participant data with other State datasets to gain a holistic look at program participation. Example research ideas are included within the Section 3, 3.2. Conducting Research.
1 The Gold Standard is the preferred, pre-defined set of data definitions and format for consumption into the longitudinal database, which States may choose to adopt as a best practice. Additional information on the Gold Standard is in Appendix C.
https://www.google.com/url?sa=i&url=https://www.nrcs.usda.gov/wps/portal/nrcs/detail/ks/about/?cid%3Dnrcseprd1417224&psig=AOvVaw2LVcLTdlXZDjvIf5q_gmN0&ust=1586534670562000&source=images&cd=vfe&ved=0CAIQjRxqFwoTCJisu-jc2-gCFQAAAAAdAAAAABAD https://www.google.com/url?sa=i&url=https://en.wikipedia.org/wiki/Supplemental_Nutrition_Assistance_Program&psig=AOvVaw03NCJQpQPTtLnsWe-5ld9v&ust=1586534740049000&source=images&cd=vfe&ved=0CAIQjRxqFwoTCJjti9Xc2-gCFQAAAAAdAAAAABAI
4.1.2 How to Apply
To apply for grant funding, or for more details regarding the grant for the SNAP LDP, please refer to the Request for Applications (RFA) https://www.fns.usda.gov/fm/grant-opportunities. FNS will send notification upon posting. While grant funds are available to support participation, States are NOT required to apply for grant funds in order to join the SNAP LDP.
4.1.3 How to Participate
Described here is the process for transmitting SNAP participation data, as defined in Section 17(n) of the Food and Nutrition Act if 2008, as amended in December 2022. States will prepare and extract SNAP participation data from their source system(s). Then each State will send monthly data on an annual basis via the Census Bureau’s secure Managed File Transfer (MFT). Details on the annual secure file transfer protocol (sFTP) can be found in Appendix D: Securely Submit Data.
Once the Census Bureau receives the data, they will perform basic quality checks and then utilize the PVS to match person records and assign unique identifiers. Finally, the Census Bureau removes all PII and stores the data in the Federal longitudinal database, which is where researchers with SSS will be able to securely access the SNAP participation data. The end-to-end process for sending data to the Federal Longitudinal Database is illustrated below in Figure 1.
Figure 1: Process to Send Data to the Federal Longitudinal Database
For security purposes, States will not receive their data back after the Census Bureau removes all PII and assigns a unique identifier. Instead, the Census Bureau will provide each State with a table package summarizing the data provided from each State’s annual submission of monthly data files.
States wishing to participate in the SNAP LDP will work with FNS and the Census Bureau to define the requirements of their MOU. States with an existing SNAP data sharing MOU will have the option to update the existing MOU with an amendment to add the SNAP LDP. States wishing to participate in SNAP data transmission for the first time may reach out to the Census Bureau to establish an MOU for the SNAP LDP. The process to amend or establish an MOU is in Appendix A: Steps for Getting Started Post-Award.
Should a State wish to limit the use of their data, the State will document additional research limitations within their MOU. States must opt into the SNAP LDP for their data to be included within the National longitudinal database. States may use existing data elements within their current MOUs and update the MOU Attachment B for participation in the SNAP LDP.

If a State does not wish to participate in the SNAP LDP, no action is necessary regardless of whether or not the State has an MOU with the Census Bureau. A State is not a part of the SNAP LDP until they have established or revised a State MOU explicitly opting into the SNAP LDP.
States are eligible to receive grant funding if participating in the SNAP LDP. The State does not need a signed MOU at the time they apply for grant funding; however, States must make contact and work with the Census Bureau to sign the MOU within 30 days of award in order to ensure there are no interruptions to funds.
4.1.4 Participation at a Glance
For a State to participate in the SNAP LDP, the State must perform the following sequential actions:
1) The State notifies FNS and the Census Bureau of interest in participating in the SNAP LDP.
Upon receiving confirmation of the State’s desire to participate, the Census Bureau will work with the State to update their existing MOU if they have one or draft a new MOU to include the SNAP LDP and associated data. Contact information is in Appendix A: Steps for Getting Started Post-Award.
2) If the State has an existing MOU, review and negotiate any additional changes to the MOU to add SNAP LDP as an approved project, including data usage and available data elements. If the State is establishing a new MOU, review and negotiate data usage and available data elements.
3) After final review and approval of the agreement, the State and the Census Bureau both sign the final agreement.
4) After finalizing signatures, the State is ready for participation in the SNAP LDP and may begin working with the Census Bureau to provide the agreed upon data. Please note, the RFA may be released prior or congruent to the development of the MOU; however, the State must begin working on the MOU with the Census Bureau within 30 days of grant award.
Figure 2: Steps for Establishing or Amending an MOU
In addition to the above steps, States may consider applying for grant funding to assist where necessary.
4.2 How to Meet Security Requirements and Transmit Data
As previously stated in Section 4, 4.1.3. How to Participate, tools and processes provided by the Census Bureau removes all PII before inclusion in the federal longitudinal database, without the loss of research functionality. The removal of PII prevents researchers from accessing PII and aligns with the security requirements established within Section 17(n) of the Food and Nutrition Act of 2008, as amended in December 2022.
https://www.google.com/url?sa=i&url=https://www.nrcs.usda.gov/wps/portal/nrcs/detail/ks/about/?cid%3Dnrcseprd1417224&psig=AOvVaw2LVcLTdlXZDjvIf5q_gmN0&ust=1586534670562000&source=images&cd=vfe&ved=0CAIQjRxqFwoTCJisu-jc2-gCFQAAAAAdAAAAABAD https://www.google.com/url?sa=i&url=https://en.wikipedia.org/wiki/Supplemental_Nutrition_Assistance_Program&psig=AOvVaw03NCJQpQPTtLnsWe-5ld9v&ust=1586534740049000&source=images&cd=vfe&ved=0CAIQjRxqFwoTCJjti9Xc2-gCFQAAAAAdAAAAABAI
Additionally, the State will send data via the Census Bureau’s sFTP. The State will provide adequate documentation and support of transferred files for the Census Bureau to be able to interpret the data for the uses permitted in the MOU, including definitions of active participant records, a record layout, record count, record length, and data dictionary. For more information, see Appendix D: Securely Submit Data.
The Census Bureau can handle multiple file types/formats and will work with each State to identify a viable data format. However, the Census Bureau prefers the following data formats:
• Fixed length text file, and
• PIPE “|” delimited text file.
Furthermore, the Census Bureau encourages the compressing or zipping of files and will work with the State to identify a common name for the files.
4.3 Project Requirements
As stated, the goal of the SNAP LDP is to enable program research over time and across State lines. As such, participating States are to share monthly information, on an annual basis, regarding households and members of households that receive benefits, including the data elements listed below.
The following data elements are required, if available:
• Demographic characteristics (e.g., name, SSN, sex, DOB, & education level),
• Income and financial resources,
• Employment status, and
• Household circumstances, such as deductible expenses.
The following data elements are considered optional, but preferred, if available:
• Earnings and employment data from the State Department of Labor and
• Health insurance program data.
As previously stated, the Census Bureau will establish the PIK and remove all PII. States may further define the above availability of these data elements within their MOU. Even if not all data elements specified in Section 17(n) of the Food and Nutrition Act of 2008, as amended in December 2022, are available, a State is still eligible to participate and receive the associated grant funding. States may reference a summary of the grant application process, the period of performance implementation activities, and the SNAP LDP maintenance activities in Appendix B: SNAP LDP Process Map.
4.4 SNAP Gold Standard
The SNAP Gold Standard is an optional standardized data format developed to facilitate the processing and use of SNAP data across States and over time. The SNAP Gold Standard format, as further defined in Appendix C: SNAP Gold Standard and NIEM, contains data definitions and an example format for States to submit both individual and case level files.
FNS highly encourages the use of the SNAP Gold Standard to streamline the process for incorporating State SNAP data into the national longitudinal database and as part of broader efforts across the agency to promote State data standardization. However, it is not mandatory that States use the SNAP Gold Standard to participate in the SNAP LDP or to receive grant funding. In addition, FNS highly recommends that States submit data using NIEM, which is also found in Appendix C. States can request grant funding to work towards the SNAP Gold Standard and to enable participation in NIEM.
4.5 Project Outreach
In addition to this Parameters of Participation, FNS will announce funding availability to make States aware of the grant opportunity associated with this project. FNS may also provide virtual or pre-https://www.google.com/url?sa=i&url=https://www.nrcs.usda.gov/wps/portal/nrcs/detail/ks/about/?cid%3Dnrcseprd1417224&psig=AOvVaw2LVcLTdlXZDjvIf5q_gmN0&ust=1586534670562000&source=images&cd=vfe&ved=0CAIQjRxqFwoTCJisu-jc2-gCFQAAAAAdAAAAABAD https://www.google.com/url?sa=i&url=https://en.wikipedia.org/wiki/Supplemental_Nutrition_Assistance_Program&psig=AOvVaw03NCJQpQPTtLnsWe-5ld9v&ust=1586534740049000&source=images&cd=vfe&ved=0CAIQjRxqFwoTCJjti9Xc2-gCFQAAAAAdAAAAABAI recorded training sessions and webinars to support States interested in participating and to answer any questions.

5. Appendix A: Steps for Getting Started Post-Award To get started on your multi-year SNAP LDP award, the following steps must be initiated within the first 45 days of the start of the award date.
Finalize Grants Award with FNS Grants Management
Complete all steps in the “Award Notification” email. These steps include:
1. Establishing an ASAP account with FNS or provide your ASAP ID number.
2. Signing of the FNS-529 by the authorized agency official and return to the appropriate
FNS grants officer.
3. Confirming access to the FNS Food Program Reporting System (FPRS) and a Level 2 e-authentication account.
4. Prepare to submit quarterly FNS-908 Performance Progress Reports (PPR) and financial status reports (SF-425) to the grant and program officers.
Attend Grant Kick-Off Call with FNS SNAP
After award notification, the Program Officer will invite States to participate in a kick-off call with all SNAP LDP Grantees. At the kick-off meeting, your State will provide an overview of the proposed project approach, confirm timelines and State points of contact, and raise any questions about the grant process or your State project. FNS will also use this time to outline expectations for how your State should coordinate with FNS and the Census Bureau as part of this effort.
Work with the Census Bureau to begin MOU Signature Process & Establish Data Sharing Approach and Timeline
SNAP LDP Grantees are required to establish or amend an existing MOU with the Census Bureau, including the negotiations on data usage and available data elements. After final review and approval of the agreement, your State and the Census Bureau will sign the finalized MOU.
Contact Kathy Reeves (Katherine.L.Reeves@census.gov) to inquire if your State already has an existing SNAP data sharing agreement or will require a new one. Existing SNAP data sharing agreements will require revisions to add SNAP LDP to the approved data use purposes. A template MOU can be found in Appendix E of the SNAP LDP Parameters for Participation.
Please note, the RFA may be released prior or congruent to the development of the MOU; however, States must begin working with the Census Bureau within 30 days of grant award notification to avoid interruption of funds. The end-to-end negotiation and signature process can take up to five months, so States must begin coordination with the Census Bureau early in their implementation.
Establish Process for Submitting Quarterly Reports to FNS
States are required to submit quarterly status reports (also known as Performance Progress Reports) for the duration of their award. States are to submit quarterly status reports to the SNAP LDP Grants Officer and Program Officer, via email, by the due dates listed in the table to the right. More information about Performance Progress Reports, including a template and training materials, can be found on the FNS website. The below table indicates what the reporting period is for each quarter and when the Performance Progress Report is due at the conclusion of each quarter.

7. Appendix C: The SNAP Gold Standard and NIEM The Gold Standard is the preferred, pre-defined set of data definitions and format for consumption into the longitudinal database, which States may choose to adopt as a best practice. While FNS highly encourages the use of the Gold Standard, it is not mandatory that States use the SNAP Gold Standard to participate in the SNAP LDP or to receive grant funding.
To comply with the SNAP Gold Standard, the State will send monthly files an an annual basis that contain the State's SNAP population.
The two tables on the following pages, CASE LEVEL DATA and INDIVIDUAL LEVEL DATA, include the requested data elements for the recommended SNAP Gold Standard. Each file contains data element definitions, formats, and examples. In addition, Attachment A, SNAP Gold Standard is for States to reference and contains example files.
• Case level describes the family unit or household.
• Individual level describes the individuals within each family unit or household.
Furthermore, FNS highly encourages States to participate in NIEM within the Human Services domain.
Information on NIEM is found at https://www.niem.gov/communities/human-services.
States can apply for grant funding to both work towards the Gold Standard and/or participate in NIEM to create a robust dataset to support information sharing and interoperability.
Please reach out to the Census Bureau early on to discuss the SNAP Gold Standard format and any questions about how it applies to your States data.
