What a BCBA role should actually contain — and how to check the one you're offered
Job descriptions in ABA are written by people who need a seat filled, not by people describing the work. Here is what the role should contain, the eight questions that reveal what it actually contains, and the answers that should stop you signing.
- At least 60% of a BCBA role should be analyst-level work — assessment, programme design, training, supervision — not direct implementation.
- Ask for the active caseload number and total weekly therapy hours; sustainable guidance is 6–12 clients comprehensive and 130–250 hours overseen.
- A role that cannot tell you its supervision ratio is telling you it does not have one; the standard is 1–2 hours per 10 hours of direct treatment.
- Ask how many BCBAs have held the post in 24 months. Turnover in ABA runs 30–50% and reaching 70% in some settings, so the answer is diagnostic.
- If documentation time is not scheduled or paid, treat it as an unadvertised 20% addition to your working week.
Job descriptions describe the vacancy, not the work
An ABA job description is written by someone who needs a seat filled. It is not a dishonest document, it is an incomplete one — and the gaps are consistently in the same places.
Genuine hiring in ABA moves quickly. A BCBA-level role typically runs one to three weeks from first contact to offer.[5] That speed is good for you, and it also means you have very little time to work out what you are actually accepting.
The eight questions below take one conversation. They are all operational facts rather than negotiating asks, which is why a reluctance to answer any of them is itself the answer.
What the role should contain
At least 60% analyst-level work. That is the BACB's threshold for unrestricted activity in supervised fieldwork,[3] and while it formally applies to trainees, it is a reasonable benchmark for what a certified BCBA's week should look like.
Analyst-level (should dominate)
- Assessment and reassessment
- Programme design and revision
- Data analysis and clinical decision-making
- Parent and caregiver training
- Supervision and training of RBTs
Technician-level (should be the minority)
- Direct implementation of a protocol you did not design
- Covering sessions because nobody else is available
Cover work happens in every clinic. The question is whether it is the exception or the staffing model. A role that is 50% session cover is an RBT post with a BCBA salary attached and a BCBA's liability.
The eight questions
- What is the active caseload number, today? Not the target. Today.
- What total weekly therapy hours would I be overseeing? Sustainable guidance is roughly 130 to 250.[2] Ten intensive clients can exceed fifteen focused ones.
- What is the supervision ratio, and is it actually delivered? The standard is 1 to 2 hours of case supervision per 10 hours of direct treatment.[1] A clinic that does not know its ratio does not have one.
- What proportion of my week is analyst-level versus direct? If they cannot answer, ask for last month's actual split for the person leaving.
- Is documentation time scheduled and paid? If not, add roughly 20% to the advertised working week and recalculate the hourly rate.
- How is travel compensated? On an in-home caseload this is the single largest hidden cost.
- How many BCBAs have held this role in the last 24 months? Turnover in ABA runs 30% to 50%, reaching 70% in some settings.[4] Third holder in two years is a structural signal.
- Who signs my supervision hours, if I need them, and what is their current trainee load? Above three or four trainees, expect delays.
Reading the answers
| Question | Reassuring answer | Concerning answer |
|---|---|---|
| Active caseload | A specific number, given immediately | "It varies" / "we'll see how you get on" |
| Weekly therapy hours | They know it, or offer to check | Never heard the metric |
| Supervision ratio | A stated ratio and how it is protected | "As needed" |
| Analyst vs direct split | An honest percentage, including cover | "You'll wear a lot of hats" |
| Documentation time | Scheduled, inside paid hours | "Most people finish up at home" |
| Travel | A rate, or caseload built around geography | "It's not much driving" |
| Previous holders | One, with a clear reason for leaving | Hesitation, or three in two years |
| Supervision sign-off | A named person with capacity | "We'll sort something out" |
The right-hand column is rarely deception. It is usually a clinic that has never measured any of this — which tells you exactly as much as a bad answer would.
The red flags that matter most
Ranked by how reliably they predict a bad year:
"It varies" about caseload. Every other problem downstream of this one. A clinic that will not commit to a number has no intention of capping it.
Documentation done at home, described as normal. This is unpaid work presented as culture. It is also the earliest reliable predictor of burnout.
No pay range at offer stage. In a market with roughly 1.6 open roles per certified BCBA, an employer refusing to state a number is not protecting a negotiating position — they have not decided what the role is worth.
Three BCBAs in two years. Whatever caused the first two to leave has not been fixed, or they would tell you what changed.
Supervision described in the future tense. "We're building out our supervision structure" means there isn't one, and you are the person who will be asked to build it on top of a full caseload.
The two things to get in writing
You will not get everything in writing, and you should not ask to. Two are worth insisting on:
- A caseload cap — expressed in clients and total weekly therapy hours
- Whether documentation time is inside paid hours
Those two determine whether the job is sustainable. Everything else — pay, title, start date — is negotiable later. Caseload never is, once you are inside it.
If both are refused, you have not lost anything. You have found out in one conversation what most people find out in month four.
Common questions
What should a BCBA actually spend their time on?
Analyst-level work — assessment and reassessment, programme design, data analysis, parent and caregiver training, and supervision of RBTs. The BACB fieldwork standard requires 60% unrestricted activity for trainees, and it is a reasonable benchmark for a qualified role too.
What is a reasonable caseload to be offered?
Published guidance suggests 6 to 12 clients for comprehensive programmes and 10 to 15 for focused ones, with a BCBA overseeing roughly 130 to 250 total weekly therapy hours. Ask for both numbers, because client count alone hides intensity.
What are the warning signs in a BCBA job description?
No caseload number, no supervision ratio, "competitive" pay with no range, a long-open posting, and duties that are mostly direct implementation. Any one is a question; three together is a pattern.
Should I ask how many people have held the role before me?
Yes, and specifically within the last 24 months. Turnover in ABA runs 30% to 50% and up to 70% in some settings, so a role on its third BCBA in two years is telling you something structural.
Is it reasonable to ask for these things in writing?
Yes. Caseload cap, supervision ratio, whether documentation time is paid, and travel compensation are all operational facts, not negotiating concessions. An employer that will not commit them to writing is signalling how flexible they will be later.
