Early Intervention: Services for Children Under 3

What Is Early Intervention in Illinois?

Illinois' Early Intervention (EI) program, run through Child and Family Connections, provides free or low-cost evaluations for children under 3 who may have developmental delays, including autism. If your child qualifies, they can receive therapies such as speech, occupational, and physical therapy at little to no cost, based on your income. EI is family-centered, meaning you'll work with a team to create an Individualized Family Service Plan (IFSP).

How to Access Early Intervention

To get started, contact your local Child and Family Connections office. A referral can come from your pediatrician, but you can also self-refer. The evaluation is free, and services are typically covered by Medicaid or private insurance. If you're uninsured, the cost is on a sliding scale. Early intervention can be a critical first step, and our service can later help you transition to ABA therapy when your child turns 3.

Illinois Medicaid Waivers for Autism

Home-Based Support Services Waiver

The Home-Based Support Services (HBSS) waiver is a Medicaid program that provides funding for children and adults with intellectual or developmental disabilities, including autism. It covers in-home supports like respite care, personal assistance, and habilitation. To qualify, you must meet income and disability criteria. The waitlist can be long, so apply early. Once approved, you can use the funding for ABA therapy from a BCBA provider.

Other Medicaid Programs

Illinois also offers the Children's Home and Community Based Services (HCBS) waiver for children under 18 who need a higher level of care. Additionally, the state's Medicaid program, HealthChoice Illinois, covers ABA therapy for eligible children. Our free service can help you find a BCBA-led provider that accepts these plans.
