Resource | Research | Payment Accuracy and Program Integrity Improper Payments to WIC Vendors 2005-2008

About every 7 years, FNS performs a nationally representative study to examine the extent of error and abuse among food vendors authorized to accept WIC vouchers. The last bookend study was the 2005 WIC Vendor Management Study, which used fiscal year 2005 expenditure data to derive an estimate for 2004. Between bookend studies, there is a need to derive annual estimates of the level of improper payments for compliance with the Improper Payments Information Act of 2002. The purpose of the subsequent annual studies was to provide annual updates to the bookend studies using the developed aging methodology.

Resource | Research | Promoting Healthy Eating WIC and Head Start: Partners in Promoting Health and Nutrition for Young Children and Families

The WIC and Head Start programs share common goals. Both programs strive to promote positive health and nutrition status for young families. Both programs provide young children and families with nutritious foods, health and nutrition education, and assistance in accessing on-going preventive health care. In many communities, WIC and Head Start serve the same families. By working together, programs have an opportunity to coordinate these services and maximize use of scarce resources (e.g., funding, staff, space). Working together can mean minimizing duplicative efforts on the part of families and staff; more opportunities for WIC and Head Start to benefit from each program’s strengths, expertise and best practices; and ultimately, more ways to make a positive impact on good health and nutrition for children and families.
