The School Lunch Eligible Non-Participants Study, conducted for USDA's Food and Nutrition Service, was designed to determine "why children eligible to participate for free and reduced-price meals do not apply or participate" in school nutrition programs.

The study examined the costs charged to SFAs (reported costs), as well as those costs incurred by the school district in support of SFA operations, but not charged to the SFA (unreported costs). Together, the reported costs and the unreported costs are the full cost of meal production.
