ABA Therapist Turnover: What's Normal and What Your Provider Owes You

ABA therapist turnover is common in the field, so if your child’s RBT keeps changing, it is not only happening to you. Most day-to-day ABA is delivered by behavior technicians, and the field has a hard time keeping them. A change can go smoothly when the provider gives notice, overlaps the old and new therapist, and keeps the same BCBA watching closely. It goes badly when your child just meets a stranger at the door one morning.

This guide covers what the research says about technician turnover, what a provider should do when someone leaves, what to ask before you sign on, and when the pattern is a reason to look elsewhere.

Who is on your child’s ABA team?

Your child’s ABA team usually has two layers:

• The behavior technician works with your child in most sessions. Many hold the national Registered Behavior Technician (RBT) credential. Washington also has a state credential, the certified behavior technician. RCW 18.380.010 defines that role as a paraprofessional who carries out the treatment plan “under the close, ongoing supervision” of a licensed behavior analyst, and who does not design the plan. The minimum training under RCW 18.380.050 is 40 hours.
• The BCBA (a licensed behavior analyst in Washington) assesses your child, writes the plan, sets the goals, and supervises the technicians.

Technician changes are the ones families see most. The BCBA is the person who holds your child’s history, data, and goals, so a stable BCBA matters more than any single technician. If you want to check a BCBA’s credential, our BCBA guide explains how.

How common is RBT turnover?

There is no single reliable number, and you should be skeptical of anyone who quotes one without saying where it came from. Here is what we could verify:

• The research is thin. A 2019 systematic review by Novack and Dixon found that turnover rates for behavior technicians had not been reported in the research at all. As the closest comparison, it pointed to community direct-care staff who support people with developmental disabilities, whose turnover has been reported as high as 70.7% to 77% per year. Those figures come from studies published in 1994 and 2002, of a related workforce, not ABA technicians specifically.
• Many technicians say they might leave. The same review cites a 2015 survey of behavior technicians in which 38% said they were highly or somewhat likely to resign.
• Many leave the credential entirely. In early 2025, the BACB surveyed people whose RBT certification expired in 2024 and who held no other BACB credential, so these were not technicians who moved up to become behavior analysts. The survey went to 30,018 people, according to the BACB’s December 2025 newsletter. That is one year of lapses, not a turnover rate.

Accreditation groups and practice software companies also publish turnover benchmarks drawn from provider data. They describe technician turnover as high, but the full reports sit behind member logins or sign-up forms, so we could not see how each one measures turnover. We could not check their figures or methods against the original reports, so we have not repeated them here.

The practical takeaway: if your child will be in ABA for a year or longer, it is reasonable to expect at least one technician change and to ask how it will be handled before it happens.

Why do ABA therapists leave?

The BACB’s 2025 exit survey asked former RBTs to pick every reason that applied. Of the 1,386 people who answered (a 4.6% response rate, so read it as a signal, not a census), the most chosen reasons were:

• Life took them in a different direction, though they liked the work: 58%
• Inadequate pay: 57%
• Poor treatment by their company: 44%
• Concerning issues in the workplace: 42%
• Limited room to grow, the number of weekly hours, and lack of supervisor support: 41% each
• High work demands with clients, and an unpredictable schedule: 38% each

Several of those are things a provider controls: pay, scheduling, how supervisors support staff. That is why the staffing questions below are worth asking. A provider’s finances matter too. Unpredictable pay was chosen by 34% of respondents, and providers occasionally close or stop serving an area. The BACB Ethics Code names funding disruption as one of the interruptions a behavior analyst has to plan for.

Can changing therapists affect my child’s progress?

We could not find a study that directly measured how technician changes affect children’s outcomes. The 2019 review put the risk this way: frequent turnover “may disrupt the continuity of services,” which may potentially slow a child’s progress. That is a reasonable concern, not a proven effect.

Two things are better established.

Missed hours add up. A study of 334 children referred for ABA in a large California health system, by Choi and colleagues, found that only 28% received a full ABA dose. Only 46% were still in services after 24 months. The authors concluded that low dosing and dropping out may reduce the benefit of ABA. The study did not look at staffing, but a technician leaving with no replacement is one way sessions get missed. Our page on how many hours of ABA therapy explains how hours are set.

Trust has to be rebuilt. Your child’s comfort with one adult does not transfer automatically to the next one. A new technician should spend time pairing, which means joining your child’s favorite activities before placing many demands. Our post on pairing in ABA covers what that should look like, including re-pairing after a staff change.

In the first few weeks after a change, watch for harder arrivals, more refusal at the start of sessions, skills that were steady starting to slip, or new challenging behavior. If you see any of these, ask the BCBA to show you the data from before and after the change, and what they are adjusting.

What should happen when your child’s therapist leaves?

The BACB Ethics Code for Behavior Analysts applies to BCBAs and BCaBAs. It does not set a notice period for technician changes, but several sections apply directly to your child’s BCBA:

• Section 3.14, continuity of services. Behavior analysts must act to avoid interruption or disruption of services. Service agreements must include a general plan of action for interruptions. When an interruption happens, the behavior analyst must tell all relevant parties what steps they are taking.
• Section 3.11, documentation. Records must be kept in a way that allows timely transition of services if needed.
• Section 3.16, transitioning services. When your child moves to a different behavior analyst, inside or outside the organization, the BCBA must provide a written plan with target dates, transition activities, and who is responsible for each step, and review it as the transition goes.

Section 3.16 covers BCBA changes. For a technician change, here is what a good handoff usually includes:

1. Notice. You hear as soon as the provider knows, with the new person’s name and start date.
2. Overlap sessions. The outgoing technician works alongside the new one, or the BCBA joins the new technician’s first sessions. Ask how overlap is scheduled and whether it counts toward your child’s authorized hours.
3. A written profile of your child. Favorite things, how your child communicates, early signs of distress, what helps them calm, and the current goals.
4. Extra supervision early on. The RBT Handbook requires supervision for at least 5% of an RBT’s service hours each month, with at least two face-to-face, real-time contacts, and at least one observation of the RBT working. That is a floor. During a handoff, it is fair to ask for more.
5. A plan for gaps. If there will be missed sessions, you should know how many, who can cover, and how hours will be made up.
6. A check-in. A short conversation with the BCBA after two or three weeks about how your child is adjusting.

How many RBTs should my child have?

No BACB rule or Washington law sets a number. It depends on your child’s hours, the setting, and how the provider staffs cases.

Some programs plan for two or three technicians on purpose. That way a sick day does not cancel your child’s whole week, and your child practices skills with more than one adult. That is a reasonable design, as long as each technician is trained on your child’s plan and the BCBA stays the same. What matters more than the count is that the people are familiar to your child, and that new ones are introduced with a plan.

Questions to ask about staffing at intake

You can ask these on the first call. A provider that answers them concretely is more useful to you than one that promises turnover will never happen.

• Who will my child’s BCBA be, and how long have they been with you?
• How many technicians will work with my child, and why that number?
• When a technician leaves, how much notice will I get, and how will I be told?
• Do new technicians have overlap sessions before working with my child alone?
• How often will the BCBA observe sessions, and does that increase after a staff change?
• If no technician is available, what happens to my child’s scheduled hours?
• What does your service agreement say about service interruptions?
• If the BCBA changes, will I get a written transition plan?

Our full list of questions to ask a new ABA provider covers goals, data, and parent involvement too.

When frequent changes are a reason to switch providers

One technician leaving is not a reason to leave a provider that is otherwise working. A pattern is different. Consider a change when:

• the BCBA changes repeatedly, or you cannot get time with them
• technicians change with no notice and no overlap
• weeks of sessions are cancelled with no plan to fill them
• new technicians start without the BCBA observing
• your child’s progress stalls and no one will show you the data
• your child’s distress around new staff is brushed off

Before you leave, ask for a meeting with the BCBA or clinical director. Name the problem, the change you need, and a date for a response. Keep in mind that a new provider means new staff, so a switch is a transition too. Our guide to switching ABA providers explains how to do it without a long gap in services.

How Orchid handles changes on your child’s team

At Orchid, every child’s plan is written and supervised by a BCBA. Our approach is trauma-informed, and when challenging behavior is part of the picture, our team uses Practical Functional Assessment, which responds to early signs of distress instead of waiting for behavior to escalate. That matters most when your child is getting to know someone new.

Parents are the people who stay constant through any staff change. Our parent training helps you use the same strategies at home, so your child’s skills do not depend on one therapist.

Orchid runs academies for children ages 2 to 15 in Issaquah (Creekside Academy and Maple Street Academy) and East Wenatchee, school-based ABA at The Kineo School and Sammamish Children’s School, and in-home ABA in Bellevue, Bothell, Kirkland, Sammamish, Covington, Federal Way, Auburn, and the East Wenatchee area. Ask us any of the staffing questions above on your intake call. Request a call back, or read more about ABA therapy at Orchid.
