Why Is There a Waitlist for ABA Therapy? (And What Families Can Do About It)

The Hardest Part of an Autism Diagnosis Nobody Warns You About
Your child has just received an autism diagnosis. You ask the pediatrician what to do next, and they say the same thing nearly every family hears: "Start ABA therapy as soon as possible — early intervention makes a real difference."
So you call every ABA clinic in your area. And one by one, you hear the same answer: "We'd love to help, but our next available opening is in four to six months. Would you like to be placed on our waitlist?"
You're not alone. ABA therapy waitlists are one of the most common — and most painful — experiences for families navigating autism care in the United States right now. In April 2026, as Autism Awareness Month highlights the growing demand for services, families across the country are facing waits of three months to over a year before their child can start therapy.
Here's what's driving the shortage, and — more importantly — what you can do about it today.
Why Is There a Waitlist for ABA Therapy?
The short answer: demand for ABA therapy has grown dramatically faster than the workforce trained to deliver it. Several forces are converging at the same time, creating a gap that families are caught in the middle of.
1. More Children Are Being Diagnosed with Autism
The CDC now estimates that 1 in 36 children in the United States has autism — a rate that has increased significantly over the past decade. More diagnoses means more families seeking ABA services, all at the same time, in the same local markets.
Earlier and better diagnostic tools are a good thing. But the service infrastructure hasn't scaled at the same pace as identification.
2. There Aren't Enough Board Certified Behavior Analysts (BCBAs)
ABA therapy must be supervised by a BCBA — a credentialed professional who designs and oversees each child's treatment plan. You cannot simply hire more therapists without having enough BCBAs to supervise them.
The numbers tell a stark story. According to a 2025 employment demand report published by the Behavior Analyst Certification Board (BACB), there were over 132,000 BCBA job postings in 2025 alone — a 28% increase year-over-year. The demand for BCBAs is projected to grow another 22% through 2029.
Meanwhile, BCBA exam pass rates have fallen to historic lows. First-time pass rates dropped from 66% in 2020 to just 51% in 2025, even as the number of people attempting the exam increased by more than 50%. Training programs have struggled to keep up with an updated exam format introduced in 2025. Fewer new BCBAs entering the workforce each year directly limits how many children can access therapy.
3. Insurance Complexity Slows Everything Down
Before a child can start ABA therapy, providers must verify insurance coverage, obtain authorization, and complete a detailed assessment. For Medicaid-covered children, prior authorization paperwork alone can take weeks. For private insurance, the authorization process often involves appeals, letters of medical necessity, and re-authorization every 90 to 180 days.
All of this administrative work falls on the same clinicians trying to see patients — taking time away from care and slowing the intake process for everyone.
4. Medicaid Rate Cuts Are Shrinking Provider Networks
Many families rely on Medicaid to fund ABA therapy. But in 2025 and 2026, multiple states have cut the rates they pay ABA providers — sometimes dramatically. Indiana implemented a 6% rate cut in April 2026 with another 4% cut planned for 2027. Vermont reduced reimbursement rates to the point that some clinics stopped accepting Medicaid patients entirely, leaving children without access to previously approved services.
When clinics can't cover their costs serving Medicaid patients, they reduce their Medicaid caseload — or exit that market entirely. The families with the fewest financial resources are often the hardest hit.
5. Rural and Suburban Areas Have the Fewest Providers
ABA providers cluster in metropolitan areas where they can attract BCBAs and serve a high volume of patients. If you live in a rural county or a mid-sized suburb, there may be only one or two clinics within a reasonable distance — and their waitlists fill quickly.
How Long Are ABA Therapy Waitlists?
Wait times vary significantly by location, provider type, and insurance. Here's what families typically report:
- Urban areas with many providers: 1–3 months for center-based ABA; longer for in-home
- Suburban areas: 3–6 months is common
- Rural areas: 6 months to over a year; some families report never finding a local provider
- Medicaid-covered children: Often face longer waits as fewer providers accept Medicaid
- In-home ABA specifically: Frequently longer due to travel requirements and limited RBT availability
The earlier your child begins ABA therapy, the stronger the research support for long-term outcomes. Every month on a waitlist matters. That's why acting strategically — right now — makes a real difference.
What Can Families Do While Waiting for ABA Therapy?
Getting on a waitlist is not the end of the story. Here are the most effective steps families can take to shorten their wait and support their child in the meantime.
1. Get on Multiple Waitlists at Once
This is the single most important step. Don't wait for one clinic to call you back before contacting the next. Reach out to every qualified provider in your area simultaneously, get placed on all of their waitlists, and then accept the first opening that comes available.
Use ABA Navigator's provider directory to find and contact multiple clinics in your area. Filter by insurance accepted, location, and service type to make your outreach as efficient as possible.
2. Ask About Cancellations
Many clinics have a cancellation list that moves faster than the standard waitlist. When you call to join the waitlist, explicitly ask: "Do you keep a cancellation list? Can you add us?" Being on both lists doubles your chances of getting an earlier start date.
3. Consider Telehealth ABA
Telehealth-delivered ABA has grown significantly and is now covered by many insurance plans. For some goals — particularly language development, parent training, and mild behavioral challenges — telehealth ABA can be a meaningful bridge while you wait for in-person services. It also expands your geographic reach, since you're not limited to providers in your immediate area.
When searching for providers, filter for telehealth availability to find options that may have shorter wait times.
4. Ask Your Insurance for a Gap Exception
If your insurance plan has an in-network provider shortage in your area, you may be entitled to an out-of-network exception at in-network rates. This is called a "network adequacy" or "gap exception" request. Call the member services number on your insurance card and ask specifically: "Can I request a gap exception for ABA therapy due to provider unavailability in my area?"
This doesn't always work, but when it does, it can unlock providers you couldn't otherwise afford.
5. Ask About Parent Training While You Wait
Many ABA clinics offer parent training programs — structured sessions where a BCBA teaches you specific behavioral strategies to use at home with your child. These programs typically have shorter wait times than full therapy, and the skills you learn can meaningfully support your child's development while you wait for services to begin.
Ask every clinic on your list: "Do you offer parent training for families on your waitlist?"
6. Look Beyond Your Nearest Providers
If your immediate area has long waitlists, expand your search radius. A clinic 30 to 45 minutes away may have openings that local providers don't. For center-based ABA, some families find that a longer commute is worth it to start therapy months sooner.
7. Connect with Your State's Autism Resource Network
Every state has autism-specific resource organizations that can help you navigate waitlists, understand your rights, and find alternative funding sources. Your state's Developmental Disabilities agency may also be able to assist with priority placement for children under age 5.
Don't Give Up on Finding the Right Provider
ABA therapy waitlists are frustrating, but they are not permanent. Provider availability changes constantly — new clinics open, therapists return from leave, children age out of programs and open slots. Families who stay active in their search — keeping in regular contact with their waitlisted clinics, regularly checking for new providers, and exploring every option — consistently find care sooner than those who wait passively.
ABA Navigator's directory lists thousands of ABA therapy providers across the United States, searchable by location, insurance, and service type. Start your search today, get on multiple waitlists, and ask every question on this list — because your child's progress doesn't have to wait.
