The National Survey of WIC Participants (NSWP) study series is designed to describe state and local agency characteristics, examine participants’ characteristics, assess participants’ experiences with WIC, and estimate improper payments resulting from certification errors in WIC. The study is conducted approximately every 10 years, and the current study is the third iteration (NSWP-III) in the series.
This is the third study in the Access, Participation, Eligibility, and Certification study series, conducted in school year 2017-18. FNS relies upon the APEC series to provide reliable, national estimates improper payments made to school districts operating the NSLP and SBP. APEC studies also help identify sources of error and inform FNS policy and technical assistance for state agencies and school food authorities to reduce error. FNS conducted previous iterations of the study in school years 2005-06 and 2012-13.
