Resource | Research and Data | Payment Accuracy and Program Integrity 2005 WIC Vendor Management Study

In 1991 and 1998, FNA conducted national studies of WIC vendors to determine the extent of vendor violation of program rules. After the 1998 study, FNA issued regulations to correct vendor practices. The 2005 study replicates the 1998 study to determine whether the regulations were effective, and to measure the frequency of vendor violations and the degree to which vendors charge accurate prices for WIC transactions.
