What California’s list coversSchools that filed the affidavit
The private schools that filed California’s Private School Affidavit with the Department of Education and reported six or more students, from CDE’s map of the 2024-25 affidavits. Smaller private schools, many of them home-based, aren’t in it, and filing isn’t approval: CDE evaluates and endorses none of them. NCES’s survey counted 3,145 private schools in California in 2021-22.
