* Charter Schools: A public charter school is a publicly funded school that operates independently under a legislative contract (or "charter") with a state, school district, or designated authorizing entity. Charters grant these schools greater operational flexibility over curriculum, staffing, and budgeting in exchange for strict accountability to achieve performance standards established in their charter agreement.

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).
