Welcome and thank you for visiting Diagnostic Center Northern California’s website.

The Diagnostic Center, Northern California (DCN) is one of three regional assessment centers operated through the State Special Schools and Services Division of the California Department of Education. The diagnostic centers were established over 60 years ago, initially to provide services to students with cerebral palsy.In 1955, the scope was broadened to include children with other neurological handicaps.The two other centers are located in Fresno and Los Angeles.
