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 | Payment Accuracy and Program Integrity The Extent of Trafficking in the SNAP: 2012–2014

Trafficking of Supplemental Nutrition Assistance Program benefits occurs when SNAP recipients sell their benefits for cash to food retailers, often at a discount. Although trafficking does not increase costs to the federal government, it is a diversion of program benefits from their intended purpose of helping low-income families access a nutritious diet. This report, the latest in a series of periodic analyses, provides estimates of the extent of trafficking during the period 2012 through 2014.

This report provides the 2015 national estimate of incorrect payments for the meal reimbursements. The assessment calculates both overpayments and underpayments for FDCHs that earn either Tier 1 (higher) or Tier II (lower) reimbursements depending on the location and circumstances of the child care provider or the participating children.

Resource | Research and Data | Assessing/Improving Operations Second Access, Participation, Eligibility, and Certification Study (APEC II): Estimating and Validating Statistical Models for Updating Estimates of Improper Payments in NSLP and SBP

Statistical models were designed to estimate national improper payments due to certification error on an annual basis using district-level data. This enables FNS to update its estimates of national improper payment rates for the NSLP and SBP in future years without having to conduct full rounds of primary data collection.
