The Tennessee Department of Intellectual and Developmental Disabilities hopes to become the first accredited state system focused on disabilities. Department Commissioner Jim Henry said the goal is to lead the nation in offering those types of services. A series of meetings will be held across the state targeting providers, families, and advocates. The DIDD became a stand-alone department in 2011 and will contract with the Council on Quality and Leadership to consult about accreditation. The three-year process will begin in August.
