¹ National School Lunch Program (NSLP): The National School Lunch Program is a federally assisted meal program operating in public and nonprofit private schools. It provides nutritionally balanced, low-cost or free lunches to eligible children each school day based on household income thresholds or community eligibility options (CEO).
