King County Coalition for Developmental Disabilities

We help people develop the relationships and skills they need to change systems.



We are people with disabilities, families and neighbors, and professionals who work in health, education, and social services. We protect and promote the rights of people with intellectual and developmental disabilities (IDD) and work to build inclusive communities.


Some of the the policy areas we work on:


  • Access to inclusive, high quality early learning and child care
  • Access to inclusive K-12 education, where all students feel they belong and are a member of the school community
  • Access to habilitative services across the lifespan that help individuals keep, learn or improve skills needed for daily living
  • A chance to work, volunteer or otherwise contribute to the community
  • Affordable housing and safe communities
  • Support for family caregivers
  • Access to community-based health and social services
