Resource | Research and Data Understanding Risk Assessment in SNAP Payment Accuracy

This study provides an overview of the risk assessment tools currently used by the state agencies that administer the Supplemental Nutrition Assistance Program to categorize those program applications more likely to incur payment errors and allocate resources to improve the accuracy of benefit payments to families participating in SNAP.

Resource | Research and Data WIC Infant and Toddler Feeding Practices Study-2: Ninth Year Report

This report, in the WIC Infant and Toddler Feeding Practices Study 2 (WIC ITFPS-2)/ “Feeding My Baby” Study analyzes the long-term impact of the USDA’s Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) by gathering information on caregivers and children over the first nine years of the child's life after enrollment in WIC, regardless of their continued participation in the program.

Resource | Research and Data Erroneous Payments In Childcare Centers Study (EPICCS)

The Payment Integrity Information Act of 2019 requires federal agencies, like FNS, to give Congress information about payment errors for federal programs, like CACFP. FNS planned this study to estimate payment errors in CACFP child care centers. However, after completing the study, FNS found an error in the method used to estimate nationwide findings from the study data. Because of the error, FNS is not publishing the full study, and will instead present key findings that relate to broad trends instead of specific estimates.

Resource | Research and Data Feasibility Study: Calculating Meal Claiming Error in Family Day Care Homes That Participate in CACFP Using State Monitoring Review Data

We explored the feasibility of using existing data from state monitoring reviews – a process designed to assess operations and provide real-time technical assistance to family day care homes operating CACFP – to estimate the rate of improper payments in those operations. This study found that flexibility in these reviews and the information they report across states, while beneficial for their main purpose, made the resulting data unusable for estimating a national improper payment rate.

Resource | Research and Data | Food/Nutrient Analysis Indicators of Diet Quality, Nutrition, and Health for Americans by Program Participation Status, 2011–2016: The SNAP Report

This study is the fourth in a series that uses the National Health and Nutrition Examination Survey data to examine the relationship between SNAP participation and indicators of diet quality, nutrition, and health. As in previous studies, this study compares SNAP participants with income-eligible and higher income nonparticipants, by age and gender.

Resource | Research and Data | Assessing/Improving Operations Third National Survey of WIC Participants

The National Survey of WIC Participants (NSWP) study series is designed to describe state and local agency characteristics, examine participants’ characteristics, assess participants’ experiences with WIC, and estimate improper payments resulting from certification errors in WIC. The study is conducted approximately every 10 years, and the current study is the third iteration (NSWP-III) in the series.

Resource | Research and Data | Assessing/Improving Operations Study of Nutrition and Activity in Childcare Settings in USDA’s CACFP

Centers and family daycare homes participating in CACFP play an important role in supporting the health and wellness of the children they serve. The Study of Nutrition and Activity in Childcare Settings  is the first nationally representative, comprehensive assessment of the CACFP. Data were collected in program year 2016–17 from CACFP providers and participating children on nutritional quality of meals served, nutrient intake of participating children, meal costs and revenues, and more. Findings serve as an important baseline for the subsequent updates to the meal pattern and nutrition standards, which were implemented in October 2017.

Resource | Research and Data | Assessing/Improving Operations Third Access, Participation, Eligibility, And Certification Study (APEC-III), SY 2017-18

This is the third study in the Access, Participation, Eligibility, and Certification study series, conducted in school year 2017-18. FNS relies upon the APEC series to provide reliable, national estimates improper payments made to school districts operating the NSLP and SBP. APEC studies also help identify sources of error and inform FNS policy and technical assistance for state agencies and school food authorities to reduce error. FNS conducted previous iterations of the study in school years 2005-06 and 2012-13.
