What is Connecticut's Birth to Three Program?
Connecticut's Birth to Three System is the state's early intervention program for infants and toddlers from birth to age three who have developmental delays or disabilities. It is part of the federal Individuals with Disabilities Education Act (IDEA) Part C program. The program is administered by the Connecticut Department of Public Health (DPH) and provides a range of services to support the child's development and family's capacity to meet their child's needs.
For families of young children showing signs of autism spectrum disorder (ASD), Birth to Three can be a critical entry point for early intervention services, including Applied Behavior Analysis (ABA) therapy. ABA therapy uses evidence-based techniques to improve communication, social skills, and adaptive behaviors while reducing challenging behaviors. When started early-before age three-ABA can have profound, lasting effects on a child's development.

How ABA Therapy Fits into Birth to Three
Eligibility and Evaluation
To access ABA through Birth to Three, your child must first receive a comprehensive evaluation to determine eligibility. Evaluations are provided at no cost to families and assess five areas: cognitive, physical, communication, social/emotional, and adaptive development. If your child has a diagnosed condition like autism with a high probability of developmental delay, they may automatically qualify. For other children, a 25% delay in one area or a 33% delay in two areas typically meets criteria.
During the evaluation, a team including a service coordinator, early intervention specialists, and possibly a BCBA will assess your child's needs. If ABA is recommended, it will be written into the Individualized Family Service Plan (IFSP).
The IFSP and ABA Services
The IFSP is a written plan that outlines your child's developmental goals, the services needed to achieve them, and the settings where services will be delivered. For ABA therapy, the IFSP will specify the number of hours per week, the focus areas (e.g., communication, play skills, self-care), and the provider. Services are meant to be provided in the child's natural environment-most often the home, but also daycare or community settings.
ABA provided through Birth to Three is typically short-term, intensive, and focused on functional skills. A BCBA (Board Certified Behavior Analyst) will design and oversee the intervention, while registered behavior technicians (RBTs) may deliver direct therapy hours. The family is actively involved in coaching and implementation.
Costs and Insurance Coverage for ABA Through Birth to Three
Is Birth to Three Free?
Connecticut's Birth to Three program is free for evaluation, service coordination, and IFSP development. However, for ongoing services like ABA, families may be charged a fee based on a sliding scale tied to income. Many families pay nothing, while others may have a copay. Crucially, Birth to Three must use public and private insurance when possible to pay for services, which can reduce or eliminate out-of-pocket costs.
Connecticut law requires that most private health insurance plans cover medically necessary autism treatment, including ABA therapy, for children under age 19. HUSKY Health (Connecticut's Medicaid program) also covers ABA. If your child has insurance, the Birth to Three program will seek reimbursement from your plan. You cannot be turned away due to inability to pay.
Coordinating with Insurance
Because ABA therapy can be expensive without coverage, understanding how it coordinates with Birth to Three is vital. The program works with your insurance to maximize benefits. In some cases, if your insurance offers robust ABA coverage, the services may shift to being wholly insurance-funded. Your Birth to Three service coordinator can help navigate this process.
If your child receives ABA outside of Birth to Three (e.g., through a private clinic), you may still be able to participate in the program for other services. However, for seamless early intervention, many families choose ABA within the Birth to Three system or use our free matching service to find a BCBA-led provider who accepts their insurance.

Practical Tips for Families Starting Birth to Three ABA
- Be proactive with documentation: Keep a folder with your child's evaluation reports, IFSP, insurance cards, and any medical diagnoses. This helps when coordinating between Birth to Three and insurance.
- Ask for a BCBA with early childhood expertise: Not all BCBAs specialize in toddlers. Request providers who have experience with children under three and natural environment teaching.
- Get involved in the IFSP meeting: Your input on your child's strengths and needs is essential. Come prepared with questions about ABA goals, hours, and how to support progress at home.
- Understand your rights: Birth to Three has a clear procedural safeguard. You can dispute decisions, request mediation, or file a complaint if you disagree with the IFSP.
- Seek parent support groups: Connecting with other families using Birth to Three can provide emotional support and practical strategies. Autism- and early intervention-focused groups exist statewide.

Common Mistakes to Avoid
Waiting Too Long to Refer
Many families notice signs of autism before age two but delay referral thinking their child will 'grow out of it.' Early intervention is most effective when started as early as possible. Connecticut's Birth to Three allows referral at any time from birth to age three. Trust your instincts: if you have concerns, get an evaluation.
Not Understanding the IFSP as a Legal Document
The IFSP is not just a plan; it is a binding agreement. If the services listed are not being provided or are inadequate, you have the right to advocate for changes. Some families do not realize they can request specific ABA strategies like natural environment teaching, caregiver coaching, or a certain number of hours.
Assuming ABA Can't Be Fun or Play-Based
Some parents worry ABA will be too rigid for a toddler. In early intervention, ethical ABA is play-based, child-led, and embedded in everyday routines. A good BCBA will make therapy feel like fun interactions, not drills. Ask potential providers about their approach to young children.
Overlooking Transition Planning
Before your child turns three, Birth to Three will help transition to the school system's special education preschool (Part B of IDEA). If you plan to continue ABA outside of school, start researching private providers and using our matching service well before the third birthday, as waitlists can occur.
