Castaic Union School District


Castaic Union School District is a public school district serving unincorporated Castaic, portions of unincorporated Valencia, and a very small portion of the city of Santa Clarita, California within Los Angeles County, California, offering elementary and secondary instruction, grades pre-K through eighth. Until 1890, it was known as the "Castec School District."
A small portion of the district's boundaries reside within the city limits of Santa Clarita. The vast majority are commercial and industrial properties along with vacant parcels, However, a very small portion of residential and multi-family properties located near the intersection of Newhall Ranch Rd and Copper Hill Dr are actually within the city limits of Santa Clarita, and lie within the boundary of the Castaic Union School District..
Although Castaic High School, now being planned, will lie well within the district's boundaries, it will instead be controlled by the William S. Hart Union High School District and the school board already in place which oversee its sixteen high schools, junior high schools, and charter schools. The Hart District offices are located thirteen miles southeast of the new Castaic High School site in the city of Santa Clarita.
