What these agencies may control or connect to

Eligibility and service coordination

Developmental-disability eligibility, case management/service coordination, functional assessment and person-centred planning can sit here or in a closely connected state/local system.

HCBS and community support

Residential support, respite, day/community supports, supported employment, self-direction and waiver services may be administered directly or through Medicaid partners.

Waiting lists and crisis routes

Ask what waiting or interest list exists, how priority is decided, what emergency/crisis exceptions exist and what can be appealed.

Agency labels were reviewed against the NASDDDS state-agency directory on 24 August 2026. Use the live directory for current leadership, address, telephone and website.
