BCBA Supervision Requirements: What the BACB Requires for Fieldwork

BCBA supervision requirements are not confusing because any one rule is especially difficult. They get confusing because several different things have to be true at the same time.

You can have enough supervised hours and still be missing a required contact. You can have the right supervision percentage but miss the client observation. You can complete perfectly appropriate fieldwork and create a documentation problem that does not get noticed until months later.

I see trainees focus on the percentage more than anything else. They calculate 5% or 10%, see that the number works, and assume the month is fine.

Sometimes it is.

Sometimes it absolutely is not.

And right now there is another layer to all of this because several BCBA fieldwork and supervision requirements change in 2027.

So rather than throwing a giant BACB checklist at you, I want to explain how the pieces actually fit together.

The numbers first

There are two fieldwork types.

Supervised Fieldwork requires 2,000 total hours.

Concentrated Supervised Fieldwork requires 1,500 total hours.

Under the current requirements, Supervised Fieldwork requires at least 5% supervision each month. Concentrated Supervised Fieldwork requires at least 10%.

Supervised Fieldwork also requires at least 4 real-time supervisor-trainee contacts during the month. Concentrated Supervised Fieldwork requires at least 6.

You can currently accrue between 20 and 130 fieldwork hours during a calendar month.

At least 50% of your total supervised time must be individual supervision, and at least 60% of your total fieldwork must ultimately consist of unrestricted activities.

You also need the required client observation during each supervisory period.

Those are the basic numbers.

The part that gets people into trouble is treating them as if they are interchangeable.

They are not.

If you accrue 100 hours of Supervised Fieldwork, for example, you need at least 5 supervised hours. If you accrue 100 hours of Concentrated Supervised Fieldwork, you need at least 10.

But reaching 5 or 10 supervised hours does not erase the contact requirement, the individual-supervision requirement, the client observation, or anything else that applies to that month.

Everything has to line up.

The same thing is true when people compare 2,000 Supervised Fieldwork hours with 1,500 Concentrated Supervised Fieldwork hours.

Concentrated fieldwork is not just regular fieldwork with 500 hours magically removed. You receive more supervision while accruing those hours, which is why fewer total fieldwork hours are required.

You can also combine Supervised and Concentrated Fieldwork. Concentrated hours receive additional weight when the two fieldwork types are combined.

What you cannot do is finish a month and decide afterward that you would rather call it concentrated because it gets you closer to being done.

The requirements for the fieldwork type you are claiming need to have actually been met during that supervisory period.

What actually has to happen every month

The supervisory period is a calendar month, and I think that is one of the easiest details to underestimate.

A month is not just a convenient block of time on your tracker. It is the period during which several requirements have to be satisfied.

Your supervision percentage has to work.

Your required number of contacts has to occur.

Enough of your supervision has to be individual.

The required client observation has to happen.

Your total fieldwork hours have to stay within the monthly limits.

And your documentation needs to support what you are claiming.

You cannot miss a contact in January and fix it by having an extra meeting in February. February does not travel backward in time.

The same basic problem applies to other monthly requirements.

This is why I would never recommend waiting until the last couple of days of the month to figure out whether everything works.

By then, some problems can still be fixed.

Others cannot.

There is also a timing issue at the very beginning of fieldwork.

You cannot start accumulating hours just because you found a BCBA who is willing to supervise you. You need the required supervision arrangement in place first, including a qualified supervisor and supervision contract, and you need to have reached the appropriate point in your qualifying coursework.

Hours completed too early do not become eligible later because someone eventually signed the paperwork.

The order matters.

Your supervisor matters too.

A fieldwork supervisor has to meet the BACB's requirements for providing supervision. There are additional requirements for newer BCBAs, and supervisors need the required supervision training.

But I would look beyond whether somebody technically qualifies.

Your supervisor is helping determine whether your activities count, reviewing your performance, monitoring your progress, and ultimately signing documentation connected to those hours.

A BCBA can technically qualify to supervise and still be a terrible supervisor.

Those are two very different things.

The 2027 transition is where things get messy

If you are accruing fieldwork in 2026 and you are not completely sure whether you will apply before or after January 1, 2027, this is the part I would pay especially close attention to.

The total number of required fieldwork hours does not change in 2027.

Supervised Fieldwork still requires 2,000 hours.

Concentrated Supervised Fieldwork still requires 1,500.

The 5% supervision requirement for Supervised Fieldwork stays the same too.

Several other things do change.

The Concentrated Supervised Fieldwork requirement changes from 10% supervision to 7.5%.

The maximum number of fieldwork hours that can be accrued in a month increases from 130 to 160.

The client-observation requirement changes from the current observation requirement to a cumulative-duration requirement.

Beginning in 2027, Supervised Fieldwork requires at least 60 cumulative minutes of client observation during the month.

Concentrated Supervised Fieldwork requires at least 90 minutes.

The problem is that you cannot assume whichever version of the rules is more convenient will eventually apply to your hours.

The requirements that matter are the requirements that apply when you submit your certification application.

Imagine that you accrue 160 fieldwork hours during a month because the 2027 requirements allow it, but then you end up applying under requirements that only permit 130.

You cannot assume all 160 hours will qualify.

The concentrated-supervision percentage creates the same kind of issue.

A month completed at 7.5% may meet the 2027 concentrated requirement, but 7.5% does not somehow become 10% if you later need that month to qualify under the current requirements.

This is why anyone crossing the 2026-to-2027 transition needs to think ahead.

I would much rather see someone intentionally structure and document fieldwork so that they preserve their options than try to reverse-engineer several months of hours later.

That is when this stuff becomes a nightmare.

Online supervision still has to meet the same requirements

Yes, BCBA supervision can be completed online.

I am mentioning this because I have heard from plenty of trainees who did not even realize that what they were searching for as "online BCBA supervision" was often being called "remote BCBA supervision."

The terminology can make something pretty straightforward sound like two different services.

It is not.

Online supervision still has to meet the same fieldwork requirements.

That includes client observation.

A client observation can be completed through an appropriate remote format, including recorded video when the applicable requirements are met.

But observation and real-time supervision are not automatically the same thing.

If your supervisor watches a recorded client interaction later, that may satisfy the observation requirement. It does not magically create a real-time contact between you and your supervisor.

Those are separate requirements.

If you and your supervisor later review that interaction together in real time, talk through what happened, and discuss feedback, that is a different situation.

The point is that online BCBA supervision is not a watered-down version of fieldwork supervision. The format may be remote. The requirements still have to be built into the experience.

If online supervision is specifically what you have been trying to find, our Remote BCBA Supervision program explains how we structure it.

Unrestricted hours are another place trainees get confused

At least 60% of your total BCBA fieldwork must be unrestricted.

That does not mean exactly 60% of every individual month has to be unrestricted.

And 40% restricted does not mean you are supposed to go out and accumulate 40% restricted fieldwork.

Forty percent is the maximum.

There is no minimum amount of restricted fieldwork you have to complete.

That distinction surprises people.

Unrestricted activities are generally the activities that look more like the work you will eventually be expected to perform independently as a BCBA.

Depending on the client and the fieldwork experience, that can include things such as conducting observations, analyzing data, conducting assessments, researching literature related to current client programming, training caregivers or staff, and developing or revising behavior-analytic programming.

Restricted activities are primarily the direct delivery of therapeutic or instructional procedures.

This also connects to another question I get all the time: Do you have to be an RBT to complete BCBA fieldwork?

No.

Being an RBT and completing BCBA fieldwork are separate things.

An RBT can certainly accrue BCBA fieldwork, but RBT supervision requirements and BCBA supervised fieldwork requirements are not interchangeable.

Meeting one does not automatically mean you met the other.

And you do not have to become an RBT just because you need fieldwork hours.

What matters is whether the activities qualify, whether they are connected to appropriate client services, whether the supervision requirements are being met, and whether everything is documented correctly.

For some people, working as an RBT is a perfectly reasonable way to gain experience.

It is not the only way to become a BCBA.

Documentation is where good hours can become bad hours

I wish trainees worried about documentation earlier than they usually do.

A lot of people understandably focus on getting the hours first.

Then somebody needs to sign a monthly form, something does not match, and suddenly everyone is trying to remember exactly what happened 3 months ago.

That is not where you want to be.

Your supervision contract should be in place before the fieldwork starts.

During fieldwork, your documentation needs to be detailed enough to show what you actually did, when you did it, whether the activity was restricted or unrestricted, when supervision happened, what type of supervision occurred, and whether the other requirements for the month were met.

Your Monthly Fieldwork Verification Form documents the supervisory period.

Your Final Fieldwork Verification Form documents the fieldwork being submitted at the end of the experience.

Those forms are important, but they are not a substitute for the records underneath them.

If your fieldwork is ever reviewed, you need documentation that supports what you claimed.

A beautifully completed verification form does not fix bad underlying records.

And this is another reason I would not leave everything until the end of the month.

If your documentation is being maintained as the fieldwork happens, you can catch problems while there is still time to do something about them.

If you are reconstructing everything later, you are working from memory and hoping.

That is a terrible compliance system.

What I would want a trainee to remember

If you forget half the percentages and numbers in this article 20 minutes after reading it, I am not particularly worried.

You can look numbers up.

What I would want you to remember is that BCBA fieldwork is a system.

No single requirement exists by itself.

Your hours, supervision, contacts, observation, unrestricted activities, documentation, and supervision structure all have to work together.

The point of fieldwork is not to become incredibly good at filling out a tracker.

It is supposed to prepare you to function independently as a behavior analyst.

That means learning how to analyze what is happening with a real client, make defensible decisions, communicate with caregivers and other people involved in treatment, evaluate whether something is working, change course when it is not, and behave like somebody who will eventually be responsible for making those decisions without a supervisor sitting beside them.

The numbers create the structure around that experience.

What you actually learn inside that structure matters just as much.

And if you are accruing hours during the 2026-to-2027 transition, please do not build months of fieldwork around the assumption that you will definitely apply on one side of January 1 unless you actually know that.

Plan ahead.

Your future self will be much less annoyed with you.

If you need BCBA fieldwork but cannot leave your current job, do not want to become an RBT, or do not have your own client, that is exactly why we built our supervision model differently.

Applied Behavior Analysts provides remote BCBA supervision and online supervision with a client provided through our practice. Fieldwork is predominantly unrestricted and supervision is individualized.
