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.

To manage the Child Nutrition programs effectively, FNS collects and analyzes information from annual State-level management reports. However, because these State-level reports vary considerably in both format and content, FNS is unable to rely on this source for all of its ongoing information needs.

The study collected data on-site on food, labor, and other meal production costs for a five day period. A major goal was to test the feasibility of identifying meal production costs that were not charged to the SFA account (to obtain full costs) and directly allocating costs to different SFA activities.
