Charter schools: how they work

  • 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.
  • Its own rules, its own accountability. The charter frees the school from some state or local rules; in return it must meet the standards written in its charter. It is nonsectarian.
  • 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.

Sources: 20 U.S.C. 7221i (federal Charter Schools Program definitions); NCES, Condition of Education: Public Charter School Enrollment. Each state writes its own charter law, so ask the school how enrollment works there.
