What Autism Services Are Available in Washington?
Washington offers a range of autism services, from early intervention to school-based support and adult programs. The key is knowing where to look and what you qualify for.
Early Intervention for Children Under 3
If your child is under 3, Washington's Early Support for Infants and Toddlers (ESIT) program provides free evaluations and low-cost services. This is run through local Educational Service Districts (ESDs) like ESD 112 in Vancouver or ESD 105 in Yakima. Services can include speech therapy, occupational therapy, and developmental support, often at no cost to families based on income.
School-Based Services for Children 3-21
Once a child turns 3, public schools in Washington must provide a free appropriate public education (FAPE) under IDEA. This can include ABA, speech therapy, and social skills training through an Individualized Education Program (IEP). Contact your local school district, like Seattle Public Schools or Spokane Public Schools, to request an evaluation.
Community and Nonprofit Programs
Nonprofits like the Autism Society of Washington and local chapters of The Arc offer support groups, respite care, and resource navigation. Some, like the Washington Autism Alliance, provide free or low-cost legal advocacy to help families access services.
How to Get Autism Services at Low or No Cost
Cost is a major barrier, but Washington has several pathways to affordable care.
Medicaid (Apple Health) Coverage
Washington's Medicaid program, Apple Health, covers ABA therapy for children under 21 with an autism diagnosis. You must apply through the Washington Healthplanfinder or your local Department of Social and Health Services (DSHS) office. Once enrolled, you can find ABA providers who accept Apple Health, though waitlists can be long. A free matching service can help you find providers with availability.
Private Insurance Mandates
Washington state law requires most private insurance plans to cover autism-related therapies, including ABA, up to a certain amount. Check your plan's benefits-many cover diagnostic evaluations, behavioral health, and therapy. If you have high deductibles, ask about out-of-pocket maximums or payment plans.
Sliding-Scale Clinics and Community Health Centers
Community health centers, such as Sea Mar Community Health Centers in Western Washington or CHAS Health in Spokane, offer sliding-scale fees based on income. They can provide diagnostic evaluations, mental health support, and primary care. Some also offer ABA therapy or referrals.

How to Get Started with ABA Therapy in Washington
ABA therapy is a cornerstone of autism support, focusing on building skills and reducing challenging behaviors. Here's how to access it affordably.
Step 1: Get a Diagnosis
You'll need a formal autism diagnosis from a qualified professional, like a developmental pediatrician or psychologist. Low-cost options include the University of Washington Autism Center's clinic (which offers sliding-scale fees) or community mental health centers. Waitlists can be months long, so start early.
Step 2: Verify Insurance Coverage
Call your insurance company and ask: "Does my plan cover ABA therapy?" For Apple Health, confirm your child's eligibility. For private plans, ask about copays, deductibles, and any pre-authorization requirements. Some providers offer free insurance verification through a matching service.
Step 3: Find a BCBA-Led Provider
ABA therapy is most effective when led by a Board Certified Behavior Analyst (BCBA). Use a free service like ABA Centers Near Me to get matched with vetted providers in Washington who accept your insurance. This saves time and ensures quality.
