Early Intervention and ABA in Connecticut
For Connecticut parents of children under 3: Part C is the faster door than insurance. Here's how to use it.
Start with Part C, Not Insurance
If your child is under 3 and you're worried about development, Connecticut's Part C early intervention program is the fastest first step. It's federally required in every state, and you don't need an autism diagnosis to request an evaluation. You just need a concern.
Part C and insurance-funded ABA are separate systems. You can use them in sequence or together. Part C gets you in the door quickly, while insurance can cover ABA therapy that Part C may not provide.
How to Request an Evaluation
In Connecticut, you request an evaluation in writing. Contact your local Part C program, often called Birth to Three. You can find the contact through your pediatrician or the state's early intervention website.
Your written request should include your child's name, date of birth, and your concern. The program has 45 days from referral to complete the evaluation and, if eligible, develop an Individualized Family Service Plan (IFSP). That timeline is federal, so it applies in Connecticut.
What an IFSP Includes
An IFSP is your family's plan for services. It lists your child's strengths and needs, your family's concerns and priorities, and the specific services your child will get. It also names the service coordinator who will guide you.
The IFSP is reviewed every six months and updated at least annually. You're part of the team that writes it, and you must agree to it before services start.
Where Services Happen and What They Cost
Part C services happen in your home or in community settings like daycare or a park. That's by design, because young children learn best in familiar environments. A provider comes to you, which removes travel time and stress.
Cost is free or sliding scale, depending on your income. Connecticut uses a sliding fee scale, so some families pay nothing and others pay a modest amount. Your service coordinator will explain the fee schedule before you commit. No one is turned away for inability to pay.
Transition to School Services at Age 3
At age 3, your child leaves Part C and may qualify for services through your local school district. This is a different system, governed by the Individuals with Disabilities Education Act (IDEA). The transition starts at least 90 days before your child's third birthday.
Your service coordinator will help you plan. The school district will evaluate your child for preschool special education. If your child qualifies, services shift to an Individualized Education Program (IEP). If not, Part C ends and you may need to rely on insurance for ABA.
Using Insurance for ABA in Connecticut
Connecticut has an autism insurance mandate, but it only applies to fully insured plans. If your employer self-funds its health plan, that plan is governed by ERISA and is not bound by state mandates. Many self-funded plans cover ABA anyway, so it's worth asking.
Medicaid covers medically necessary ABA for children under 21 through EPSDT. If your child is on Medicaid, that's a separate path from private insurance.
Limits on ABA coverage vary by plan. Some plans cap visits or hours, others don't. Don't rely on a number you read online, because plans change. Ask your insurer directly: 'Does my plan cover ABA therapy for autism? Are there annual visit or hour limits? What is my deductible and out-of-pocket maximum?'
ABA Providers Across Connecticut
We list ABA agencies across Connecticut counties. The largest concentrations are in Fairfield County, New Haven County, and Hartford County. That gives you options, but more options doesn't mean every provider is a fit.
When you call a provider, ask about waitlists, session length, and whether they accept your insurance. Also ask about their experience with children under 3, because early intervention ABA looks different from school-age therapy.
