The WIC Nutrition Services and Administration cost study examines how program funds are expended by state and local agencies to support the management and operation of WIC. The study analyzed data from a national survey of state and local agencies, cases studies, and FY 2013 WIC administrative data.

FNS developed the Access, Participation, Eligibility and Certification (APEC) study series, which collects and analyzes data from a nationally representative sample of schools and school food authorities (SFAs) about every 5 years. APEC allows FNS to develop a national estimate of erroneous payment rates and amounts in three key areas: certification error, meal claiming error and aggregation error.  FNS recently completed APEC II, which collected data in School Year 2012-2013 and this report summarizes those findings.
