What a charter school is
- Public and free. NCES describes a public charter school as a publicly funded school, usually run by a group or organization under a contract (the charter) with the state, the district or another body. The federal definition says a charter school does not charge tuition.
- Families choose it. Under the same definition, a charter school is one parents choose to send their children to, and it admits students by lottery when more apply than it has room for.
- No program badge. ChoiceFunded’s program badges and “schools that accept” lists cover private schools only. Charter schools are listed separately here, with no badge, and are never counted with private schools.
