The federal government has a long history of investing in programs for feeding children, starting with federal aid for school lunch programs in the 1930s. Today, federal child nutrition programs support food served to children in schools and a variety of other institutional settings. The child nutrition programs support meals and snacks served to children in schools, child care, summer programs, and other institutional settings in all 50 states, the District of Columbia, and the U.S. territories. The programs are administered by the U.S. Department of Agriculture's (USDA's) Food and Nutrition Service (FNS), which provides federal aid to state agencies (often state departments of education) for distribution to school districts and other participating institutions. This report starts with an overview of child nutrition programs' funding and then provides detail on each program, including a discussion of how the programs are administered at the federal, state, and local levels; eligibility rules for institutions and participants; nutritional and other program requirements; and recent policy changes.
