ABA Waitlists Across the U.S.: What Families Need to Know by State

Finding ABA therapy for your child can feel urgent — every week of progress matters. Yet across the U.S., families often face months-long waitlists before therapy begins. The length of that wait depends on where you live, who provides your services, and how many certified therapists are available nearby. 

Here’s what current data show about ABA therapy wait times by state, and how you can find providers with faster openings.

The Big Picture: Why ABA Therapy Waitlists Exist

ABA therapy is widely recognized as an evidence-based treatment for children with autism, but the demand far exceeds the supply of trained professionals.

Here’s what contributes to those long waitlists:

• Growing demand: Autism diagnoses have risen dramatically in the last decade.
• Workforce shortages: There aren’t enough Board Certified Behavior Analysts (BCBAs) and Registered Behavior Technicians (RBTs) to meet the need.
• Insurance delays: Authorization and paperwork can take weeks or months.
• Personalized care: ABA programs are custom-built, which takes time before therapy begins.

Waitlists aren’t always a bad sign — sometimes they indicate that a provider is protecting service quality and therapist workload. But for families, waiting can still feel stressful and uncertain.

How Long Are Families Waiting for ABA Therapy?

There’s no single database that reports official ABA wait times by state, but several studies, industry reports, and state-level resources give us a reliable picture.

Nationwide averages

• Surveys of ABA organizations report average wait times around 5–6 months for therapy to begin after intake.
• About 75% of families report experiencing delays due to waitlists.
• Wait times can be as short as a few weeks in some metro areas, but as long as a year or more in rural regions or states with fewer certified providers.

ABA Therapy Wait Times by State and Region

In California, families typically wait between three and twelve months to begin ABA therapy. However, in some rural northern regions, a shortage of Board Certified Behavior Analysts (BCBAs) has extended wait times beyond a year.

Meanwhile, in New York City, families report similar wait times—ranging from three to twelve months—depending on the borough and provider capacity. Urban centers tend to move faster, while suburban areas often experience longer delays due to high demand.

Moving to Massachusetts, families seeking in-home behavioral health services face average waits of sixteen to twenty weeks. This reflects the broader statewide demand for child and adolescent behavioral services.

In Florida, Medicaid’s EPSDT program requires providers to begin ABA therapy within ninety days of authorization. In reality, though, timelines can still vary by region and provider availability.

Further north in Illinois, access to autism diagnostic evaluations often takes nine months to two years, delaying the start of ABA therapy. This lengthy diagnostic process remains one of the main reasons families experience extended waits for treatment.

Similarly, in Texas, many youth behavioral health and autism programs continue to report long waitlists, showing that the demand for qualified ABA providers still exceeds the workforce supply in several regions.

In Arizona, families typically experience average wait times of four to nine months, particularly in the greater Phoenix area where service demand remains high.

Likewise, in Washington, staffing shortages and licensing delays have slowed intake for new clients, leaving some families waiting several months before receiving their first appointment.

Overall, across the United States, the average ABA therapy wait time remains around five to six months from intake to the first therapy session. However, this can vary widely even within the same state—typically shorter in major metropolitan areas with multiple providers, and much longer in rural or underserved communities.

Why Wait Times Vary So Widely

Several factors influence how long you’ll wait for ABA therapy in your state:

• Workforce availability: Fewer certified professionals means longer lists.
• Geographic access: Cities generally have more ABA clinics than rural areas.
• Insurance processing: Medicaid and private insurance authorizations can delay the start of therapy.
• Reimbursement rates: Low insurance reimbursement can limit provider growth.
• Diagnostic delays: Children often wait months for autism evaluations before even reaching ABA intake.

According to KFF’s 2024 Home & Community-Based Services (HCBS) report, the average wait for disability-related supports across the U.S. is about 40 months — not ABA-specific, but a strong indicator of broader system challenges.

How to Find ABA Providers With Faster Openings

Even with national averages hovering around 5–6 months, some families are able to start services much sooner by being proactive. Here’s how:

1. Use a verified provider directory

Skip the endless phone calls. ABA Navigator helps families find ABA providers by:

• Insurance coverage
• Location
• Service availability

You can explore ABA Navigator’s listings by service type:

• ABA Therapy
• Behavior Assessments
• Parent Training
• Social Skills Programs

2. Ask about “partial starts”

Some clinics offer early steps — like assessments or parent training — while waiting for full therapy hours.

3. Consider telehealth ABA

Virtual ABA therapy has expanded access, especially in states with limited in-person staff.

4. Get on multiple waitlists

It’s perfectly acceptable to be on several lists. Follow up often — cancellations and staffing changes can open new spots quickly.

What Families Can Take Away

The average ABA therapy wait time in the U.S. is around 5–6 months, but the experience varies dramatically from state to state.

• In California and New York, waits often range from 3–12 months.
• In rural states like Montana, Idaho, or Maine, waits can stretch even longer.
• And in some regions, strong provider networks (like Florida or Massachusetts) are working to reduce backlogs with new policies and programs.

While national data still lag, one thing is clear — access improves when families search early, use digital tools, and stay proactive about follow-ups.
