As a non-profit 501(c)(3) organization, The Arc of Washington State is composed of individuals with intellectual and developmental disabilities, their families, professionals and concerned members of the community.


The Arc’s mission is to advocate for the rights and full participation of all people with intellectual and developmental disabilities. Along with our network of members and chapters, we support and empower individuals and families; connect and inform individuals and families; improve support and service systems; influence public policy; increase public awareness; and inspire inclusive communities.


The Arc of Washington State advocates for quality services and necessary funding to meet the needs of people with intellectual and developmental disabilities and their families including birth to three services, special education, employment and residential supports, health care, transportation, respite and inclusion in the community.


The Arc partners with many other groups such as self-advocates in Self Advocates in Leadership (SAIL)People First of Washington and Allies in Advocacy. Parents of both children and adults connect through Parent to Parent, Parent Coalitions and local chapters of The Arc. The Developmental Disabilities Administration provides state-funded supports such as respite, employment supports and residential services.
