DD System Transformation

The Illinois Department of Human Services (IDHS) Division of Developmental Disabilities directly supports almost 32,000 children and adults with intellectual and developmental disabilities (I/DD) across Illinois to live person-centered lives of their choosing by supporting housing, work, recreation, and other important programs.

Developmental and Intellectual Disability System Background

In March 2023, Governor JB Pritzker and the Illinois Department of Human Services announced a three-year transformation initiative aimed at a compassionate, positive, and data-informed reshaping of the way the State approaches care for individuals with I/DD. The initiative includes a deeper investment in Home and Community Based supports and significant changes at the Choate Mental Health & Developmental Center (CMHDC) in Anna, Illinois. More than 100 of CMHDC's 250+ residents and patients will move from I/DD units on campus to other locations, guided by the wishes of themselves, their families, and/or their guardians.

As a part of this transformation, IDHS is focused on three primary actions:

  • REDUCE reliance on SODC system for long-term care and focus on expanding a comprehensive, community-based continuum of services and supports for individuals with I/DD
  • INCREASE quality of care and supervision at SODCs
  • Dramatically INCREASE community capacity through funding, technical support, and collaboration

Independent Review

As part of this undertaking, IDHS requested reviews and recommendations from three independent experts:

As the initiative progresses, IDHS is committed to keeping stakeholders and the public informed about the changes, their impact, and the improvements being made.
