What Are Early Intervention Programs?
Early intervention refers to a system of services designed to support infants and toddlers (birth to age three) who have developmental delays or disabilities, and their families. These programs are federally mandated under Part C of the Individuals with Disabilities Education Act (IDEA). In Washington, the state's early intervention system is called Early Support for Infants and Toddlers (ESIT). Services are tailored to each child's unique needs and can include speech therapy, physical therapy, occupational therapy, and ABA therapy for children with autism.

Why Early Intervention Is Crucial for Children with Autism
The early years of a child's life are a period of rapid brain development. For children with autism, early intervention can help build foundational skills in communication, social interaction, and behavior. Research consistently shows that starting therapy as early as possible leads to better long-term outcomes. ABA therapy, in particular, is an evidence-based approach that uses positive reinforcement to teach new skills and reduce challenging behaviors. By addressing developmental delays early, children can gain skills that help them succeed in school and daily life.
Washington's Early Intervention System: ESIT and IDEA Part C
What is ESIT?
The Early Support for Infants and Toddlers (ESIT) program is Washington's statewide early intervention system. It is administered by the Department of Children, Youth, and Families (DCYF). ESIT provides services to children from birth to age three who have a diagnosed condition with a high probability of developmental delay (such as autism) or who have an established developmental delay. Services are family-centered and delivered in natural environments like the child's home or daycare.
IDEA Part C in Washington
Under IDEA Part C, every state must provide early intervention services to eligible children. Washington's ESIT program follows these federal guidelines. Once a child is found eligible, a team works with the family to create an Individualized Family Service Plan (IFSP). This plan outlines specific goals and services. ABA therapy can be included in the IFSP if it is deemed medically necessary for a child with autism.

How to Access Early Intervention Services in Washington
Step 1: Referral and Screening
If you suspect your child has a developmental delay, you can refer them to ESIT directly. Referrals can come from parents, pediatricians, or other professionals. You do not need a doctor's referral to start the process. Contact your local ESIT office or call the state's Family Health Hotline at 1-800-322-2588. A service coordinator will guide you through screening and evaluation.
Step 2: Evaluation
A multidisciplinary team will conduct a comprehensive evaluation to determine if your child meets eligibility criteria. This evaluation is free of charge. If your child is diagnosed with autism or another qualifying condition, they will be eligible for services.
Step 3: Developing the IFSP
Once eligible, you will work with a team to develop an Individualized Family Service Plan. The IFSP includes specific outcomes, the types of services (such as ABA therapy), frequency, and location. You have the right to choose your providers. Our free matching service can help you find BCBA-led ABA providers who accept ESIT or private insurance.
Insurance and Cost: Making ABA Therapy Affordable
Medicaid Coverage (Apple Health)
Washington's Medicaid program, known as Apple Health, covers early intervention services, including ABA therapy, for eligible children. If your child qualifies for Apple Health, ABA therapy is typically covered with little to no out-of-pocket cost. Many ABA providers in Washington accept Apple Health.
Private Insurance
Most private health insurance plans in Washington cover ABA therapy for autism, thanks to state and federal mandates. The Washington State Health Benefit Exchange and employer-sponsored plans often include ABA benefits. Check your plan's details for copays, deductibles, and session limits. Our matching service can help you find providers who accept your specific insurance.
ESIT Funding
ESIT services are provided on a sliding fee scale based on family income. No family is denied services due to inability to pay. For children covered by Medicaid or private insurance, ESIT may bill those payers first. ABA therapy provided through ESIT is often at no cost to families who qualify.

What to Expect in an ABA Early Intervention Program
ABA therapy for young children is typically play-based and delivered in natural settings. A Board Certified Behavior Analyst (BCBA) will conduct an initial assessment to identify your child's strengths and areas for growth. Goals might include improving communication, social skills, imitation, and reducing behaviors that interfere with learning. Sessions are often one-on-one with a registered behavior technician (RBT) under BCBA supervision. Parents are actively involved in training and implementation to ensure consistency across environments.
Tips for Choosing the Right Provider and Avoiding Common Mistakes
Look for BCBA-Led Teams
Always choose an ABA provider where a BCBA oversees the treatment plan and supervises therapists. This ensures quality and adherence to ethical standards.
Ask About Experience with Early Intervention
Some ABA providers specialize in early childhood. Ask how many young children they have served and whether they are familiar with Washington's ESIT system.
Common Mistakes to Avoid
- Waiting too long to start: Early intervention is most effective when started as soon as a delay is suspected. Do not wait for a formal diagnosis.
- Not exploring all funding options: Many families are unaware that Apple Health or private insurance may cover ABA therapy even outside of ESIT.
- Choosing a provider without verifying credentials: Always confirm that the BCBA is licensed in Washington and in good standing.
- Overlooking family involvement: Effective ABA programs include parent training and collaboration. Avoid providers who do not involve you in the process.
