The Improper Payments Elimination and Recovery Act (IPERA) of 2010 (Public Law 111-204) requires all Federal agencies to calculate the amount of erroneous payments in Federal programs and to periodically conduct detailed assessments of vulnerable program components. Approximately 117,000 Family Daycare Homes (FDCHs) provide federally reimbursable meals to children through the Child and Adult Care Food Program (CACFP). 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. Tiering errors result in improper payments because misclassified family daycare homes do not receive the appropriate level of reimbursement for the meals and snacks provided to the children. The assessment also estimates the dollar amount of improper payments attributable to these tiering errors. (author abstract)
