The Washington State Developmental Disabilities Council (DDC) is one of 56 Councils nationwide that are guided by the Developmental Disabilities Assistance and Bill of Rights Act.
We bring together community partners to address critical issues, provide leadership, training, and advocate for equitable policies, programs, and practices on behalf of people with developmental disabilities and their families.
Apply to serve as a Governor-appointed Council member, join a committee or coalition, participate in advocacy events, and connect with us on social media. Together we can make a difference!
The Legislative Cutoff Calendar helps track when bills must move through each step of the lawmaking process — and why timing matters for advocacy. With the House of Origin Cutoff now here, bills are moving quickly to the next stage, making this an important moment to stay engaged and speak up.
