This layer serves as the authoritative geographic data source for all school district office locations in California. District office location and attribute information are derived from the California Department of Education's (CDE) public schools and districts directory and district enrollment file.Since the school districts in this layer are represented as point locations instead of service areas, this layer includes additional district types that do not use geographically defined service areas to determine enrollment such as county offices of education, state special schools and State Board of Education (SBE) charter schools. In order to view districts represented as service area polygons, please see the "California School District Areas" layer.The school district enrollment and demographic information are based on the 2021-22 academic year student enrollment counts collected on Fall Census Day in 2021 (first Wednesday in October). These data elements are collected by the CDE through the California Longitudinal Achievement System (CALPADS) and can be accessed as publicly downloadable files from the Data & Statistics web page on the CDE website.District records are assigned X, Y coordinates using a quality controlled geocoding and validation process to optimize positional accuracy. Most district offices are mapped to the office structure or centroid of the district office property parcel and are individually verified using aerial imagery or assessor's parcels databases. Districts are assigned various geographic area values based on their mapped locations including state and federal legislative district identifiers and National Center for Education Statistics (NCES) locale codes.
