Enrolling with Developmental Disabilities Community Services (formerly DDA)
Washington State Department of Social and Health Services (DSHS) · Washington State
The state agency that funds long-term supports for children and adults with developmental disabilities, such as respite, assistive technology and personal care. Enrolling is the first step and is separate from asking for services. You request an enrollment packet, return it with supporting documents, and receive a decision; after that you can request services, which have their own financial and functional requirements. Newer state publications call the agency Developmental Disabilities Community Services (DDCS); some of its pages still say Developmental Disabilities Administration (DDA). Phone numbers differ by region and are listed on the enrollment page.
