How to Conduct an RBT Competency Assessment: BCBA Guide

A new RBT can’t apply for certification until someone signs off on their RBT Competency Assessment. Usually that’s a BCBA who already has a full caseload, a stack of notes to review and a supervision calendar that never quite works out.

That’s why it helps to know exactly what the assessment requires before you block out the time. This guide is written for the person doing the assessing, not the candidate, and it follows the BACB RBT Handbook updated in June 2026.

Quick answer: To conduct an RBT Competency Assessment, confirm the candidate has finished the 40-hour training, use the current BACB packet, observe each task using the demonstration methods the packet allows, record the outcome for every task, and sign off. The assessment must fall within 90 days before the candidate applies.

Key Takeaways

• Timing is the main trap: after the 40-hour training, and no more than 90 days before the RBT applies.
• The assessor can’t be related to, subordinate to, or employed by the candidate.
• Use the packet the BACB lists as current: “RBT Initial Competency Assessment: Effective January 1, 2026.”
• Annual recertification assessments end after 2026. RBTs then renew every two years with 12 hours of professional development.
• Keep your own copy of everything. The BACB won’t send submitted documents back.

What is the RBT Competency Assessment?

It’s the BACB’s skills check for new RBTs. The candidate performs the tasks listed in the BACB packet for a qualified assessor, the assessor signs off, and the signed packet is uploaded with the application.

It isn’t the only hurdle. There’s also the 40-hour training, a background check, an abuse registry check and the exam. But it’s the one step where somebody at your clinic watches the candidate work and makes the call, and that deserves some care. Whoever ends up supervising this RBT will answer for the work they do with clients.

Who can conduct an RBT Competency Assessment?

A qualified BACB-certified professional who isn’t related to, subordinate to, or employed by the candidate.

Check that before anything else gets scheduled. In a small clinic it’s surprisingly easy to land on an assessor who is the candidate’s relative, or who reports to them. Catch it early and it’s a quick swap. Catch it after the packet is signed and you may be doing the whole thing again.

Most clinics just use the supervising BCBA. If more than one person assesses, talk through what “competent” looks like for each task before the first session. Two assessors can read the same line differently, and candidates will feel the difference.

When should you schedule the assessment?

It has to come after the 40-hour training ends, and within the 90 days before the application goes in. Too early and it doesn’t count.

Say a candidate finishes training in January and plans to apply in late spring. Assess them in February and you’ve probably used up the assessment before the application is even started. Wait, and book it once the application date is close.

A few other numbers sit nearby. The training itself has to stretch over at least 5 days and no more than 180. The application needs three documents (the attestation form, the training certificate and the completed assessment), and once it’s started it stays active for 90 days. The easiest approach is to pick the application date, count back, and schedule from there.

How should you prepare a candidate before assessment day?

The BACB publishes the packet, so candidates can see the task list. Let them. Nobody should meet the assessment cold.

Better still, have them practice during supervised sessions beforehand: run a session, take data, write a note, deal with a scenario that goes sideways. Ten-minute rehearsals with feedback fit into a clinic day. Hour-long review sessions usually don’t.

On assessment day itself, stop coaching. You’re there to watch.

How do you run an RBT Competency Assessment, step by step?

Start with the current packet, observe each task, score it, note how it was demonstrated, and sign only when everything is done.

1. Download the packet the BACB lists as effective January 1, 2026, and read it before the session. Last year’s printout is out of date.
2. Check that the training is finished and that you meet the relationship rule.
3. Plan how each task will be demonstrated. The packet sets out which methods are allowed, so follow it rather than going from memory.
4. Observe. Apply the same standard to every candidate, and hold back on prompting.
5. Score each task the way the packet directs, and note how it was shown.
6. Give feedback on anything missed and plan how to revisit it.
7. Sign, hand the candidate the completed copy, and keep one for yourself. The BACB doesn’t return submitted documents, so your spare may be the only one you have.

What if the candidate isn’t ready?

Don’t sign. It’s tempting to wave through someone who’s nearly there, but your signature says they demonstrated every task.

Write down which one fell short and what you saw. “Needs more practice” helps nobody. “Stopped the timer before the behavior ended” does. Set up supervised practice on that skill, then go back to it.

And keep an eye on the calendar, since the assessment still has to land within the 90 days before the application.

Which mistakes should assessors avoid?

Most of the errors here are clerical. Assessing at the wrong time. Pulling up an old packet. Missing the relationship problem until the signatures are on. Writing “did well” in the notes instead of recording the task, the method and the outcome.

Two are less obvious. First, the assessment doesn’t replace supervision. RBTs still need supervision for at least 5% of their service hours each month, with two face-to-face contacts and at least one direct observation.

Second, don’t hand out answer keys or scripts. The RBT Ethics Code (2.0) bars RBTs from cheating or helping others cheat on competency assessments, and a candidate who already has the answers isn’t really being assessed on anything.

How does the initial RBT Competency Assessment differ from recertification?

The initial assessment is for new applicants. A recertification assessment applies to current RBTs recertifying through the end of 2026, and it’s overseen by a qualified BACB-certified RBT supervisor. After that, renewal moves to a two-year cycle, though the assessment still applies to RBTs returning from voluntary inactive status.

	Initial	Recertification (through 2026)	Reentry (from Jan 1, 2027)
Who	New RBT applicants	Current RBTs recertifying in 2026	RBTs returning from voluntary inactive status
Timing	After 40-hour training, no more than 90 days before applying	No more than 45 days before the expiration date	No more than 45 days before requesting reactivation
Afterward	Upload with application, then take the exam	Two-year cycle begins, with 12 PDUs required	Certification resumes once a supervisor is on record

RBTs who recertify on or after January 1, 2026 complete one last assessment, then earn 12 hours of professional development per two-year cycle. From January 1, 2027, the form returning RBTs use is renamed the RBT Reentry Competency Assessment. The content stays the same.

How can clinics keep assessment records organized?

The signed packet is the easy part. Getting to it takes training dates, observation time, the 90-day countdown and supervision logs, and when those live in separate spreadsheets, something slips.

Some clinics use ABA scheduling software to block observation time and ABA data collection software to keep session records in one place. Whatever you use, make sure each candidate’s file shows the training completion date, the assessment date and packet version, the assessor’s name (with the relationship check done), the planned application date, and where the signed copy lives.

Supervisors and RBTs must also keep supervision documentation for at least seven years, even after the supervisory relationship ends. A filing habit now saves a scramble if the BACB ever asks.

Does the process differ in the US and Canada?

The BACB only accepts RBT applications from residents of certain countries, and its June 2026 handbook lists the US and Canada among them. In Canada, Ontario residents can no longer apply for RBT certification, and BACB exam sites exclude Quebec and Ontario.

If your clinic operates elsewhere, Brazil included, check the BACB’s current list of eligible countries before you bring candidates through the process.

Frequently asked questions

Who can serve as an RBT competency assessor?

A qualified BACB-certified professional can serve, provided they are not related to, subordinate to, or employed by the candidate. In most clinics, that is the supervising BCBA. If your only available assessor has a tie to the candidate, ask another certified colleague to assess instead.

How long is the assessment valid before the candidate applies?

The assessment must be completed no more than 90 days before the candidate submits their RBT certification application. If that window passes before they apply, the assessment would no longer meet the requirement. Schedule it close to the application date, once the training certificate and attestation form are ready.

Do RBTs still need a competency assessment to renew?

Through 2026, RBTs recertify annually with a recertification assessment. Those who recertify in 2026 complete that last assessment, then move to a two-year cycle with 12 hours of professional development. RBTs returning from voluntary inactive status still complete the assessment, called the Reentry assessment from 2027.

Can the assessment happen before the 40-hour training?

No. The BACB requires the assessment to come after the 40-hour training is complete. Have the candidate’s training certificate in hand first, then schedule the assessment so it lands within 90 days of their planned application date.

What should a clinic keep after the assessment?

Keep a copy of the signed packet, the training certificate and the application documents, since the BACB does not return submitted documents. Supervisors and RBTs must also retain supervision documentation for at least seven years. Store everything in one organized place so an audit request never turns into a search.

Conclusion

A good RBT Competency Assessment is mostly timing and paperwork. Book it inside the 90-day window, pick an assessor with no conflicts, and keep a copy of everything you sign. The skills part you already know how to do.
