ABA Therapy Waitlists: Average Wait Times and What You Can Do Now

TL;DR: The average wait time for ABA therapy is 5.7 months, with some areas reaching 12–24 months. The primary cause is a severe shortage of BCBAs — there are approximately 5 times fewer than needed to serve the current autism population. You can reduce your wait by getting on multiple waitlists simultaneously, considering telehealth options, exploring smaller or newer providers, and being flexible on setting. While waiting, pursue early intervention (free for under 3), speech therapy, occupational therapy, and parent-implemented strategies at home. The most important action: get on a waitlist TODAY — every month you wait to start the process is a month added to your child’s timeline.

The waitlist is one of the most frustrating realities of ABA therapy. You’ve recognized your child needs help. You’ve navigated the diagnosis. You’ve verified your insurance. You’re ready to start — and then you’re told it’ll be months before a spot opens up.

This guide explains why waitlists exist, how to navigate them strategically, and — most importantly — what you can do right now to support your child while you wait.

Current Wait Time Data

Metric	Average
Average wait for ABA therapy	5.7 months
Urban areas	3–6 months
Suburban areas	4–8 months
Rural areas	6–24 months
Wait for autism evaluation	4–12 months

These are averages — individual experiences vary widely based on location, provider availability, insurance type, and the specific services needed.

Why Waitlists Exist

The BCBA Shortage

The root cause is simple math. As of 2026:

81,566 BCBAs are certified nationally
Approximately 2.9 million children ages 0–21 have autism
Estimated BCBAs needed: 362,500
Shortage: approximately 280,000 BCBAs (a 5x gap)

You can’t provide ABA therapy without a BCBA to design and supervise the program. When there aren’t enough BCBAs, there aren’t enough therapy slots.

The shortage is worst in rural states. Mississippi, West Virginia, Wyoming, and Montana have fewer than 2 BCBAs per 10,000 children. Compare that to Massachusetts (12.3) or New Jersey (10.8).

Rising Demand

Autism diagnosis rates have increased from 1 in 150 (2000) to 1 in 31 (2024), and ABA therapy volume grew 267% from 2019 to 2024. Demand is growing faster than the workforce can expand.

Insurance Expansion

As more insurance plans cover ABA therapy (now mandated in all 50 states), more families can access services — which is good, but it increases demand on an already strained system.

RBT Turnover

Even when a BCBA has capacity, they need Registered Behavior Technicians (RBTs) to deliver direct therapy. RBT turnover rates are high — estimated at 30–50% annually in many organizations. When an RBT leaves, the families they serve may return to the waitlist while a replacement is found and trained.

How to Reduce Your Wait Time

1. Get on Multiple Waitlists

Don’t put all your eggs in one basket. Contact 3–5 ABA providers and get on every waitlist simultaneously. When one opens up first, you can accept that spot and remove yourself from other lists.

This isn’t rude — providers expect it. They know families need to optimize their chances.

2. Consider Telehealth ABA

Virtual ABA providers often have shorter waitlists because they don’t have physical space limitations. Telehealth options include:

BCBA supervision via video with an in-person RBT
Parent-implemented ABA coached by a BCBA via video
Hybrid models combining virtual and in-person components

Telehealth can be a bridge while you wait for in-person services, or it may become your preferred model. Read our full guide on virtual ABA therapy.

3. Try Smaller or Newer Providers

Large, established clinics often have the longest waitlists. Smaller practices, solo BCBAs, and newer organizations may have shorter waits. They may also offer more personalized attention.

4. Be Flexible on Setting

If you’re set on center-based therapy but the wait is 12 months, ask about in-home services — or vice versa. Flexibility on setting can significantly reduce your wait time. Compare the options in our guide to in-home vs. center-based ABA.

5. Be Flexible on Hours

If you’re waiting for a comprehensive (25–40 hour/week) spot, ask about starting with focused services (10–15 hours/week). Some therapy now is better than full therapy later. Hours can often be increased as availability opens up.

6. Ask About Cancellation Lists

Many clinics maintain a cancellation list for families who can start on short notice. If another family cancels or moves, you could get a spot weeks or months ahead of the regular waitlist.

7. Check for Medicaid-Specific Programs

Some states have Medicaid waiver programs or initiatives specifically designed to reduce ABA waitlists for Medicaid-enrolled children. Contact your state Medicaid office. See our Medicaid ABA coverage guide.

8. Look Slightly Outside Your Area

A provider 30 minutes away may have a significantly shorter waitlist than one 10 minutes away. If you’re in a major metro, neighboring suburbs may have more availability. For in-home services, some providers serve a wider geographic radius.

What to Do While Waiting

Waiting doesn’t mean doing nothing. Here are evidence-based steps to support your child right now:

Early Intervention (Ages 0–3)

Your state’s early intervention (EI) program provides free evaluations and services for children under 3 with developmental delays or disabilities. EI doesn’t require an autism diagnosis — a developmental concern is enough. Services may include:

Developmental therapy
Speech-language therapy
Occupational therapy
Parent coaching
Applied behavior analysis (in some states)

Contact your state’s EI program directly — you don’t need a referral.

Speech and Occupational Therapy

These services often have shorter waitlists than ABA and address overlapping needs:

Speech therapy — communication, language development, feeding issues
Occupational therapy — sensory processing, fine motor skills, daily living skills, self-regulation

Many insurance plans cover speech and OT with shorter authorization timelines than ABA.

Parent Training

Some ABA providers offer parent training while you wait for direct therapy. This teaches you ABA-based strategies you can implement at home:

Using positive reinforcement to build skills
Understanding the 4 functions of behavior
Creating visual schedules and routines
Teaching communication using your child’s current abilities
Managing challenging behaviors with function-based strategies

Even a few parent training sessions can make a significant difference.

Home Strategies You Can Start Today

Create visual supports. Visual schedules (pictures showing the sequence of daily activities) help autistic children understand what’s coming next and reduce anxiety around transitions. You can make simple visual schedules with photos printed from your phone.

Use positive reinforcement. When your child does something you want to see more of — making eye contact, using a word, following a direction — reinforce it immediately. Praise, a preferred snack, a few minutes of a favorite activity. Read about ABA therapy benefits to understand the science behind reinforcement.

Establish predictable routines. Consistent daily routines reduce anxiety and challenging behavior. Same morning routine, same bedtime routine, same sequence of events. Predictability is calming.

Follow your child’s lead in play. Sit with your child during their preferred activities. Join their world before asking them to join yours. This builds connection and creates natural teaching opportunities.

Reduce sensory overload. If your child is sensitive to noise, light, or crowds, reduce these triggers where possible. Noise-canceling headphones, dimmer lights, quieter environments. Read our guide to sensory activities for autistic children.

School Services (Ages 3+)

If your child is 3 or older, they may qualify for special education services through your school district, including:

Speech and language therapy
Occupational therapy
Social skills groups
A classroom aide
An Individualized Education Program (IEP) with accommodations

These services are free and available regardless of whether your child receives private ABA therapy. Contact your school district’s special education office to request an evaluation.

The Cost of Waiting

Research is clear: earlier intervention produces better outcomes. Every month your child waits for ABA therapy is a month of lost developmental opportunity. This isn’t meant to create guilt — many factors affecting wait times are beyond your control. But it underscores why getting on a waitlist immediately, even before you’re 100% sure, is so important.

Key research:

Children who begin ABA before age 4 show the greatest gains in IQ, language, and adaptive behavior
Each year of delay in starting ABA reduces the magnitude of improvements
Early intensive behavioral intervention can reduce lifetime support costs by over $1 million per individual

Frequently Asked Questions

Should I get on a waitlist before my child has a diagnosis?

Yes — many providers will add you to a waitlist based on a referral or developmental concern, with the understanding that a diagnosis must be obtained before therapy begins. Since diagnostic evaluations also have waitlists, starting both processes simultaneously is the most time-efficient approach.

What if the only available provider has bad reviews?

Don’t accept a poor-quality provider just because they have availability. A bad ABA experience can be worse than no ABA — it can create negative associations with therapy, waste months of treatment time, and delay progress. Use our guide to choosing an ABA provider to evaluate quality, and keep waiting for a good match if needed.

Can I change providers after starting somewhere?

Absolutely. Starting at one provider doesn’t lock you in. If a preferred provider has an opening later, you can transfer. Request your child’s records and assessment data from the current provider — you’re entitled to them — and share with the new provider to minimize redundant assessment. Read our clinic guide for tips on switching.

Do waitlists differ for in-home vs. center-based?

Often, yes. Center-based programs have physical space limitations that cap how many children they can serve. In-home programs have more flexibility to add children (as long as RBTs are available). If center-based has a longer wait, consider starting in-home and transitioning later.

How do I know where I am on the waitlist?

Call the provider every 4–6 weeks to check your status. Ask: “Where am I on the waitlist? Has anything changed? What’s your current estimated timeline?” This keeps you top of mind and ensures you haven’t been accidentally removed.
