The Deinstitutionalization Toolkit is designed to provide all those interested in institutional closures and expanded community living opportunities for people with intellectual disabilities and developmental disabilities (ID/DD) with information, strategies, state data, and case studies that can facilitate closure and build community capacity to serve more people with ID/DD in the community. It covers topics such as building a broad-based coalition, understanding and working within the political environment, creating a community system of care, and relevant laws, policies, and court decisions.
