The St. Louis Public Schools (SLPS) operate more than 75 schools, including several magnet schools. SLPS operates under provisional accreditation from the state of Missouri and is under the governance of a state-appointed school board called the Special Administrative Board, although a local board continues to exist without legal authority over the district. Since 2000, charter schools have operated in the city of St. Louis using authorization from Missouri state law. These schools are sponsored by local institutions or corporations and take in students from kindergarten through high school. In addition, several private schools exist in the city, and the Archdiocese of St. Louis operates dozens of parochial schools in the city, including parochial high schools.
