In every state, programs authorized by the Developmental Disabilities Assistance and Bill of Rights Act (DD Act) empower individuals with developmental disabilities and their families to help shape policies that impact them. DD Act programs conduct important research and test innovative new service delivery models. They work to bring the latest knowledge and resources to those who can put it to the best use, including self-advocates, families, service providers, and policymakers.

DD Act programs also investigate cases of abuse and serve as advocates for individuals with developmental disabilities and their families.
The 2000 amendments added the “provision of care that is free of abuse, neglect, sexual and financial exploitation, and violations of legal and human rights and that subject individuals with developmental disabilities to no greater risk of harm than others in the general population,” to the Bill of Rights, increased the accountability of programs funded under the Act, and aimed to increase coordination and collaboration within and across those programs.
