Programs, dollars, and people that serve autism families in Illinois. Federal protections always apply on top of what you see here.

Illinois overview

Illinois uses the PUNS (Prioritization for Urgency of Need for Services) waitlist — register with your local Community Mental Health Board as early as possible, since PUNS placement determines access to the Medicaid DD waiver. Illinois DHS Division of Developmental Disabilities administers services. The state's Family Support Program and Home-Based Support Services offer some pre-waiver supports. Equip for Equality is Illinois's Protection & Advocacy organization. RAPAC serves as the PTI network. Illinois has strong regional autism-specific resources including the CIDD at Rush University.

Verify program names, URLs, and eligibility on official .gov sites — these change.

⏰ Act now — Medicaid waiver waitlist

Illinois DD Waiver, accessed through PUNS

Typical wait: 5–10 years — selection is by time spent in 'Seeking Services'

Get on PUNS now. Illinois selects people in order of how long they have been in the Seeking Services category, so your registration date is effectively your place in line.

PUNS registration is a face-to-face interview with your local Independent Service Coordination agency. Nothing happens until it is done.

Medicaid Waiver

Home and community-based services (HCBS) for autism families in Illinois.

Illinois DD Waiver, accessed through PUNS

Illinois Department of Human Services, Division of Developmental Disabilities

People with a developmental disability or related condition — including autism, intellectual disability, cerebral palsy, epilepsy and traumatic brain injury — who may need waiver services now or in future.

How autism qualifies

Autism is explicitly named as a qualifying condition for PUNS enrollment. You can register on the basis of a suspected developmental disability, so you do not need every assessment finished before you start.

What it can pay for

Home-based support services
Respite
Community integrated living arrangements
Child group homes
Day programs and employment supports

How the waiting list is ordered

Illinois runs PUNS — Prioritization of Urgency of Need for Services — and this is the single most consequential thing for a family to understand. Selections are made by how long you have been in the 'Seeking Services' category. Not by need, not by urgency: by time. Which means the date you register is very close to the date that determines when you are selected, and a family that delays a year loses that year permanently. It also means checking which PUNS category you were placed in matters — being recorded under a planning category rather than Seeking Services can mean waiting without ever being selected.

How to apply

Arrange a PUNS interview with your local Independent Service Coordination (ISC) agency — the gateway to both PUNS and the waiver. New enrollments are done face to face with a Qualified Intellectual Disability Professional. To check your status or selection prospects, email DHS.DDD.PUNS@illinois.gov.
