For families
Why does my child keep getting a new therapist?
Every family in ABA asks this, and almost every answer online is a turnover percentage. We are not going to give you one, because we could not source it honestly, and we will show you why. What we can give you is the machinery that produces the churn — including one cause that has nothing to do with your therapist, and that your provider can fix in an afternoon.
Sourced to the BACB RBT Handbook, Updated 06/2026 and to the BACB’s published certificant counts, read 5 September 2026. Every quoted sentence is the board’s wording, not ours.
The short version. The person in the room with your child usually holds an entry-level credential that is designed to be entered quickly and maintained continuously. Three things follow: there are far more of them than there are supervisors; their certification depends on a supervisor being formally on record for them; and if that link breaks, they are barred from practicing even though nothing about their work changed. That last one is the cause nobody explains to families, and it is the one worth asking about.
1. The number you have been given, and why we will not repeat it
Search for ABA therapist turnover and you will meet the same figure everywhere: roughly 65% a year. We went looking for where it comes from.
It traces to a 2022 industry benchmark report published by an accreditation body. On 5 September 2026 we tried to open that report twice — once through an automated page reader, once with a direct request. Both times the publisher’s site handed back an automated “are you a robot” page instead of the report. We could not read it, so we will not quote it.
What we can say is what happens when you stop at the first number. Other write-ups report annual technician turnover at levels that disagree with each other so sharply that no single figure is safe to plan around — and we did not open those sources either, so we are not going to repeat any of them here.
This is a fact about our search, not about the world. The 65% figure may well be sound. We are telling you we could not open the source, which is a different statement from “it is wrong”. If your provider quotes you a turnover number, the useful follow-up is not whether it is right — it is “is that your organization’s number, or the industry’s?” Only the first one tells you anything about your child.
2. The shape of the workforce, which is checkable
The certification board publishes how many people hold each credential. As of 1 July 2026:
| Credential | Who they are | Active certificants |
|---|---|---|
| RBT | Registered Behavior Technician — usually the person delivering sessions with your child | 260,174 |
| BCaBA | Board Certified Assistant Behavior Analyst | 5,246 |
| BCBA | Board Certified Behavior Analyst — writes and oversees the program | 85,587 |
Three RBTs for every BCBA, across the whole field. That ratio is not a scandal — it is what a delivery model built on supervised technicians looks like. But it does tell you where the pressure sits, and it explains why the person you see most often is the person whose role is designed to be entered fastest.
The RBT credential is deliberately accessible: you must be at least 18, hold a high school diploma or equivalent, complete a 40-hour training, pass a competency assessment with a qualified assessor, and pass an examination. A field that can bring someone in that quickly is a field people can also leave quickly. Both halves of that are the same design decision.
3. The cause that has nothing to do with your therapist
This is the part almost nobody writes down for families. An RBT’s certification is not only a thing they earned; it is a thing that depends on a supervisor being formally recorded for them in the board’s own system. If that record lapses, the certification goes inactive — automatically, and regardless of how well the person is doing their job.
“An RBT’s certification is considered inactive if they do not have an RBT Supervisor and/or RBT Requirements Coordinator on record with the BACB. As an inactive RBT, you are not permitted to practice, bill, or represent yourself as an active RBT, and you will be listed as inactive on the Certificant Registry with ‘No Supervisor/Coordinator on Record’ as the reason for inactivity.”
— BACB RBT Handbook, Updated 06/2026, “Inactive Due to No Supervisor/Coordinator on Record”
Read that again from your side of it. Your child’s therapist can be removed from your child’s sessions because somebody else left. When a supervising BCBA resigns, every technician whose record pointed at that BCBA can drop to inactive until another supervisor adds them. Nothing changed about the technician. Nothing changed about your child. The paperwork changed.
The board also names the fix, and it is administrative rather than clinical:
“To reactivate, you must have an RBT Supervisor or RBT Requirements Coordinator add you as a supervisee in their BACB portal account.”
— BACB RBT Handbook, Updated 06/2026, same section
Which means a well-run provider treats a departing supervisor as a re-assignment exercise that happens the same week, and a badly-run one treats it as something that surfaces when a technician cannot log a session. You are allowed to ask which kind you are with.
4. The maintenance clock — it changed in 2026, and the first two-year renewal lands in 2028
Until now, an RBT has had to renew every single year, and renewal has meant more than paying a fee: it required a supervisor to sit down and re-assess the technician against a competency checklist, annually.
“You must demonstrate that you can competently perform the tasks on the RBT Recertification Competency Assessment as part of the annual requirements to maintain the RBT certification.”
— BACB RBT Handbook, Updated 06/2026
That is changing, and if you read an older guide you will be reading a rule that is on its way out. Anyone certified or recertified during 2026 moves onto a two-year cycle:
“As an RBT, you must earn 12 hours of professional development units (PDUs) during each 2-year recertification cycle… you will be required to submit a recertification application (including payment) every two years beginning in 2027.”
— BACB RBT Handbook, Updated 06/2026
What we cannot tell you is whether the yearly competency re-assessment survives that change, and we are not going to guess. The chapter setting out the post-2027 requirements does not mention it — it lists the professional development units and the application, and nothing else — but that same chapter says you will “also” need to meet other requirements it does not restate, and the handbook’s own glossary still reads: “All RBTs must annually demonstrate their ongoing proficiency in performing critical behavior technician skills as part of the requirement to maintain RBT certification.” An absence from one chapter is not a repeal. Two parts of one document point different ways, the first full cycle has not run, and nobody can yet tell you which governs.
We are spelling that out rather than smoothing it over because the annual re-assessment is a safeguard on the person working with your child — someone watching them do the actual work and signing that they can still do it. If it survives, that protection stays. Telling you it had gone, when the board’s own glossary says it has not, would take away a reassurance you still have.
5. Four questions worth asking, and what a good answer sounds like
“How long has the technician working with my child been with you?”
An organization that tracks this can answer it in a sentence. One that cannot has told you something too.
“Who is the BCBA on record as supervising them — and what happens to my child’s sessions if that BCBA leaves?”
This is section 3 turned into a question. A good answer names a person and describes a hand-over. A vague answer is the risk.
“When my child’s technician changes, who carries the program across?”
The written program should live in the clinical record, not in one person’s head. If continuity depends on the individual, every departure is a restart for your child.
“Is the person working with my child certified right now?”
You can check this yourself, free, on the board’s public certificant registry — and inactive status shows there, with its reason. Asking is normal, not adversarial. We wrote a separate guide on how to verify a therapist’s certification.
6. If you are not in the United States
The credential described here is issued by a US-based board, and its geography is changing. Two things are stated plainly in the handbook and are easy to miss:
- Ontario. Residents can no longer apply for RBT or BCaBA certification, and those already holding one have had it placed on voluntary inactive status. Ontario residents also stopped being able to apply for BCBA certification as of 30 June 2026, though existing BCBAs there can maintain theirs.
- Australia. Residents will no longer be able to apply for BACB certification from 1 January 2027. Existing certificants can maintain what they hold.
The handbook is also explicit that “existing certificants may maintain certification and reside in any country” — so a certified professional who moves does not lose the credential. But if you are outside the United States and looking for a provider today, the right question is which credential your country actually recognizes, because in several places it is no longer this one. That is a different page and an honest one is worth more than a guess; if this is your situation, the four questions in section 5 still work — substitute your own country’s registry for the board’s.
7. What we are, and what we are not
Special Learning does not assess children, does not deliver ABA services, and does not employ your child’s therapist. We train the workforce, which is why we spend our time inside the credentialing rules — and why we would rather hand you the rule and the source than hand you a number we cannot open.
If something on this page is wrong, we want to know. Every figure here is traceable to a dated document you can read yourself, and where we could not read a source we said so instead of rounding it into a claim.
