FNS developed the Access, Participation, Eligibility and Certification (APEC) study series, which collects and analyzes data from a nationally representative sample of schools and school food authorities (SFAs) about every 5 years. APEC allows FNS to develop a national estimate of erroneous payment rates and amounts in three key areas: certification error, meal claiming error and aggregation error.  FNS recently completed APEC II, which collected data in School Year 2012-2013 and this report summarizes those findings.

This study describes the characteristics, circumstances, and participation and income dynamics of zero-income SNAP households and seeks to assess whether economic and policy changes may have affected this growth.

This study was undertaken to understand why some SNAP participants shop at farmers markets and others in the same geographic area do not.

The Healthy Incentive Pilot (HIP) is being evaluated using a rigorous research design. The overall goal of the evaluation is to assess the impact of HIP on participants’ intake of fruits and vegetables. 

This study describes how farmers markets and direct marketing farmers operate and their perceived benefits and barriers to accepting SNAP.

The purpose of this study was to examine how to define “adequacy” of SNAP allotments objectively in the context of program goals to improve food security and access to a healthy diet, existing data sources that could inform an assessment of the adequacy of existing and potential alternative SNAP allotments, and new data requirements to strengthen the evidence-base and allow for further rigorous analyses. 

As the time for reauthorization of SNAP again approaches, it is useful to take stock of its accomplishments, identify those features that have contributed to its success, and look for new opportunities to strengthen operations to achieve program goals more fully. To that end, this is a summary of past research on program operations and outcomes.

The diets of most Americans fall short of the Dietary Guidelines for Americans. This exploratory analysis examines dietary patterns of low-income individuals classified as healthy and less healthy eaters based on their score on the Healthy Eating Index (HEI)-2005. The HEI-2005 is a 100-point score that measures how well populations adhere to the Dietary Guidelines for Americans. 

This study identifies how spending patterns, such as the rate at which households spend their benefit, changed following the ARRA benefit increase and analyzes how spending patterns differed across household characteristics, time and states.

The purpose of this study is to identify whether spending more money on food leads SNAP and other low-income households to purchase and consume more nutritious foods. Specifically, the study analyzed the percentage and absolute change in diet-quality measures that are associated with a 10-percent increase in food expenditures for SNAP participants and income-eligible nonparticipants. The study also seeks to identify other factors or household characteristics that may affect this relationship.
