DDA Values:

  • Respect gained through positive recognition of the importance of all individuals;

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.
