What We Do

The DDA Mission: Transforming lives by providing support and fostering partnerships that empower people to live the lives they want. Read more about DDA strategic objectives.

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 Residential and County Guidelines documents were used as the basis to create this single Developmental Disabilities Guiding Values document.
