How many supervision hours does a BCBA trainee need?

It depends which fieldwork type you are accruing. Supervised Fieldwork requires 2,000 hours with supervision equal to 5% of the hours in each supervisory period. Concentrated Supervised Fieldwork requires 1,500 hours with supervision equal to 10%. A supervisory period is one calendar month in both cases.

How much supervision does an RBT need?

A minimum of 5% of the hours spent providing behavior-analytic services in each calendar month, per the BACB's RBT Handbook. That is a certification-maintenance minimum, not a clinical recommendation — CMS's 2026 Medicaid toolkit makes that distinction explicitly and cites practice guidance recommending 10 to 20 percent.

Who can supervise BCBA fieldwork?

An active BCBA with no current disciplinary sanctions who has been certified at least one year and is meeting the ongoing supervision CEU requirement. A BCBA certified for less than a year can supervise if they receive monthly consultation from a qualified consulting supervisor. Every supervisor must also complete an 8-hour supervision training and upload the certificate to their BACB portal before signing a supervision contract.

How many contacts and observations are required per month?

For Supervised Fieldwork, four supervisor-trainee contacts and one observation with a client per supervisory period. For Concentrated Supervised Fieldwork, six contacts and one observation. At least half of supervision meeting time must be individual rather than group.

Can BCBA supervision be done remotely?

The BACB permits supervision contacts to occur in real time, which includes video. CMS's Medicaid toolkit notes that most states allow ABA telehealth but adds that ongoing supervision 'should not be completely rendered using telehealth,' and that assessments often must be in person unless a state authorizes otherwise. Your state Medicaid rules, not the BACB, are usually the binding constraint on billing.

BCBA Supervision Requirements: Fieldwork, RBT Hours and the 8-Hour Training (2026)

What the BACB actually requires for supervised fieldwork, RBT supervision and supervisor qualification — the hours, the ratios, the contacts and the observations, taken from the current handbooks. Plus why CMS now says the 5% RBT minimum is a floor, not a target.

Supervision is the part of behavior analysis with the most rules and the least clear writing about them. The requirements sit across two BACB handbooks, they differ depending on which fieldwork type you are accruing, and the numbers that matter — percentages, contacts, observations — are in tables rather than prose.

Here they are in one place, taken from the current BCBA Handbook and RBT Handbook, both updated June 2026.

Fieldwork: the two tracks

Everything downstream depends on which track you are on, and the difference is not just total hours.

	Supervised Fieldwork	Concentrated Supervised Fieldwork
Hours required to qualify	2,000	1,500
Supervisory period	1 calendar month	1 calendar month
Fieldwork hours per period	Minimum 20, maximum 130	Minimum 20, maximum 130
Supervision as a share of hours	5%	10%
Contacts with supervisor per period	4	6
Observations with a client per period	1	1

The trade is explicit: the concentrated track cuts 500 hours off the total and buys that back with double the supervision rate and 50 percent more contact.

Two further constraints apply to both tracks. At least 50 percent of supervision meeting time must be individual — one-on-one between supervisor and trainee — rather than group. And group supervision is capped at 2 to 10 trainees who share similar experiences.

Restricted versus unrestricted hours

This is where fieldwork most often goes wrong, because it is a rule about the content of your hours rather than their number.

At least 60 percent of total fieldwork hours must be unrestricted. The BACB defines restricted hours as delivering existing assessments and interventions with clients — the work an RBT does. Unrestricted hours are the activities that “more closely represent the tasks they will perform after earning BCBA certification”: conducting client observations, analyzing data, developing programs.

The practical consequence is that a trainee working full time as an RBT can accrue hours quickly and still fail the requirement, because most of those hours are restricted. If you are supervising a trainee, this ratio is worth checking monthly rather than discovering at 2,000 hours.

Who is allowed to supervise

A supervisor must meet one of two criteria:

An active BCBA with no current disciplinary sanctions, certified for at least one year, and meeting the ongoing supervision CEU requirement; or
An active BCBA with no current disciplinary sanctions certified for less than one year, receiving monthly consultation from a qualified consulting supervisor.

On top of that, every supervisor must complete an 8-hour supervision training and upload the certificate to their BACB portal account before signing a supervision contract.

That last sequence matters more than it looks. The certificate has to be uploaded before the contract is signed, and the handbook tells trainees to confirm the date their supervisor completed the training before signing. A supervisor who completes the training afterwards has not fixed the problem retroactively. Trainees can check this themselves by looking their supervisor up in the BACB Certificant Registry, which is the check worth doing rather than taking someone’s word for it.

The “ongoing supervision CEU requirement” in the first criterion is the 3 supervision CEUs inside the 32-CEU, two-year recertification cycle — rising to 4 from 1 January 2027, per the BACB’s 2027 requirements. If you supervise and you skip those three, you are not merely short on CEUs — you have stopped being eligible to supervise. Our free CEU guide covers where to get supervision credits at no cost, which is the hardest category to find free.

RBT supervision: 5 percent, and why that number is now contested

The RBT Handbook is brief on this point: an RBT must obtain ongoing supervision for a minimum of 5 percent of the hours spent providing behavior-analytic services each calendar month.

Note what that percentage is calculated on — the RBT’s service delivery hours, not the supervisor’s hours, and it is a monthly calculation rather than an average across a year.

In August 2026, CMS published its first Medicaid ABA toolkit and drew a distinction around this number that practitioners should know about. The toolkit describes the 5 percent as “a minimum credentialing requirement rather than a recommended supervision level for all cases,” and separately cites clinical practice guidance recommending 10 to 20 percent — one to two hours of supervision for every ten hours of direct treatment, or one to two hours a week where direct treatment is under ten hours.

CMS also lists conditions under which more supervision may be warranted: rapid progress or a lack of progress, severe behaviors or other complexities, early in the assessment period or treatment plan, and during transitions in the plan.

That toolkit is guidance to state Medicaid agencies, not a rule binding any practitioner. But it is the document those agencies are reading now, and an organization treating 5 percent as its target rather than its floor should expect that paragraph to come up.

Telehealth supervision

The BACB permits supervision contacts to happen in real time, which includes video. The binding constraint is usually your state’s Medicaid rules rather than the BACB’s.

CMS’s toolkit describes the current landscape: most states permit ABA by telehealth, but BCBA assessments “often must occur in person unless otherwise authorized,” and ongoing supervision and caregiver training are generally allowed but “should not be completely rendered using telehealth.” It also distinguishes synchronous, asynchronous and hybrid modalities, and notes that case supervision can run with the direct provider in person and the supervising analyst observing remotely.

If you bill Medicaid, check your state’s provider manual before building a supervision model around remote delivery. Whether a supervision activity is billable at all is decided there — see what your state pays for the fee schedules.

What to document

The handbook is specific that documentation must show both quantitative and qualitative compliance, tracked at two levels:

Each supervisory period: that the minimum number of supervisory meetings and contacts happened, plus a summary of what actually happened during each supervision meeting.
Across all fieldwork hours: the running totals, including the restricted-versus-unrestricted split.

A summary of what happened in the meeting is the part most often missing. Contact counts are easy to reconstruct after the fact; content is not. Given that CMS’s toolkit identifies “incomplete documentation” as a leading finding across seven state audits that identified at least $198.4 million in improper payments, this is not only a certification concern.

The short version

If you are a trainee: know which track you are on, because 5 percent and 10 percent are very different jobs. Watch the 60 percent unrestricted ratio monthly. Verify your supervisor’s 8-hour training in the registry before you sign anything.

If you supervise: your 3 supervision CEUs are an eligibility requirement, not just a CEU category. Four contacts and one client observation a month is the floor for standard fieldwork, and half your meeting time has to be individual.

If you run a practice: the gap between the BACB’s 5 percent RBT minimum and the 10 to 20 percent clinical recommendation is now written down in a federal document your state agency is reading. That is worth a look at your own ratios before someone else looks at them.
