The State Special Schools Division has six facilities under its jurisdiction: three residential schools and three diagnostic centers. The residential schools, which serve students ranging in age from three to 22, include Schools for the Deaf in Riverside and Fremont, and a School for the Blind in Fremont. The California Schools for the Deaf provide comprehensive educational programs composed of academic, extracurricular, and residential activities for students. The California School for the Blind is a statewide residential campus that provides intensive, disability-specific educational services for pupils who are blind, visually impaired or deaf-blind. The diagnostic centers are regionally located in Fresno, Fremont, and Los Angeles, and address the unique educational needs of California's most difficult to serve special education students. The diagnostic centers provide comprehensive assessment services for students with complex learning and behavioral problems in addition to providing Local Education Agencies staff with professional development and training opportunities. These facilities comprise a total of 960,000 gross square feet on 176 acres.
