The purpose of the study was to learn the extent to which retail grocers, defined as "vendors" in the WIC Program, authorized to provide food to WIC participants, were violating program rules and procedures, and to determine which programmatic and/or demographic variables could be associated with vendor violations.

The report is based on a telephone survey of all states with SLEB agreements and case studies of 6 states with noteworthy levels of SLEB agreement-generated activity.
