The National School Lunch Program (NSLP) provides subsidized lunches to more than 30 million children each school day. The program is means-tested; schools must obtain income data from households to certify students as eligible for free or reduced-price meals. The Access, Participation, Eligibility, and Certification (APEC) study found that one in five children certified for free or reduced- price meals in school year (SY) 2005-2006 was erroneously certified or incorrectly denied benefits. This study builds on APEC with three objectives: Develop an econometric model to identify indicators of local education authorities (LEAs) with high risk of certification error. Identify the key relationships between certification error and local characteristics. Provide a Web-based monitoring tool that will apply model parameters to annual Verification Summary Report (VSR) data.
