The federal child nutrition programs provide assistance to schools and other institutions in the form of cash, commodity food, and administrative support (such as technical assistance and administrative funding) based on the provision of meals and snacks to children. The programs provide financial support and/or foods to the institutions that prepare meals and snacks served outside of the home (unlike other food assistance programs such as the Supplemental Nutrition Assistance Program (SNAP, formerly the Food Stamp Program) where benefits are used to purchase food for home consumption). Though exact eligibility rules and pricing vary by program, in general the amount of federal reimbursement is greater for meals served to qualifying low-income individuals or at qualifying institutions, although most programs provide some subsidy for all food served. Participating children receive subsidized meals and snacks, which may be free or at reduced price. Sections in this report discuss how program-specific eligibility rules and funding operate. This report describes how each program operates under current law, focusing on eligibility rules, participation, and funding. The section describes some of the background and principles that generally apply to all of the programs; subsequent sections go into further detail on the workings of each.
