The National Association of Councils on Developmental Disabilities (NACDD) is the national membership association for the 56 Governor-appointed State Councils on Developmental Disabilities (SCDD or DD Councils) across the United States and its territories.

The DD Councils receive federal funding to support policy change and programs that promote self-determination, integration, and inclusion for all people in the United States with intellectual and developmental disabilities.

NACDD’s mission is to work with State Councils on Developmental Disabilities (SCDD) to empower people with developmental disabilities, their families, and allies to build welcoming and supportive communities through policy and practice ensuring that people with DD can live a self-directed life in the community.

People with developmental disabilities are fully included as valued members of their communities and have equal opportunities to achieve their potential, make their own decisions, and exercise their civil rights.
