A public school operated independently under a performance agreement with a school district, a county office of education (COE), or the State Board of Education. Charter schools are funded on a per-pupil basis, freed from most state regulations that apply to school districts and COEs, usually able to hire their own teachers and other staff, and subject to closure if they fail to meet their promises for student outcomes. Charter schools were originally authorized in California in 1992 (Senate Bill 1448).
