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.
