COVID-19 Read about our services...

Due to the COVID-19 outbreak, the Diagnostic Center, Southern California is not currently providing Center or Field-based assessment services. We are, however, accepting referral applications and providing services based on a service delivery model aligned with current public health agencies and the California Department of Education guidance. All referral applications and requests for assessment are evaluated on a case by case basis and any services rendered by the Diagnostic Center, Southern California are individually designed to address referral questions and concerns. As the situation with COVID-19 evolves we will continue to adjust our service delivery model to ensure the safety of staff, students, and the families we serve. Please send us a message via our Contact Page if you have additional questions.
