Developmental Disabilities Administration (DDA)

The Developmental Disabilities Administration is transforming lives by providing support and fostering partnerships that empower people to live the lives they want. The 2023-2025 DDA Strategic Plan describes our work and expected outcomes to accomplish the mission.  

People with developmental disabilities and their families are valued citizens of the state of Washington. The Developmental Disabilities Administration strives to develop and implement public policies that will promote individual worth, self-respect, and dignity such that each individual is valued as a contributing member of the community. The Developmental Disabilities Guiding Values encompasses our vision and values for inclusive communities.
