📝 Launch RBT Practice Mode

The RBT Competency Assessment is a BACB-required evaluation where a BCBA assesses 20 ABA tasks through observation and interview. It verifies practical skills, follows RBT training, and must be passed before submitting the RBT certification application.

So you’ve wrapped up your 40-hour RBT training, nice.

Now comes the part everyone stresses about a little: the RBT Competency Assessment.

This is where you go from “I understand the material” to “I can actually do this in real life.” It’s a huge milestone on the way to becoming an RBT.

Just a heads-up, this isn’t a multiple-choice test. A BCBA or BCaBA will watch you demonstrate real ABA skills through role-play, live observation, and some interview-style questions. The whole point is to make sure you can use ABA procedures safely and correctly before you start working with clients.

And if you’re feeling nervous? Totally normal. Pretty much everyone does.

With some prep and a supportive supervisor, you’ll walk into the assessment a lot more confident than you think. You’ve got this.

Why the RBT Competency Assessment Matters

The BACB designed the Competency Assessment to ensure every new RBT enters the field with solid foundational skills. It confirms that you can:

• Collect accurate behavior data
• Implement basic assessment procedures
• Teach skills using evidence-based strategies
• Follow behavior-reduction plans
• Maintain professionalism and uphold client dignity
• Know when to seek guidance from a supervisor

Think of it like a quality check.

When you pass, your BCBA is basically saying, “Yep, this person is ready to work with clients safely, ethically, and without accidentally causing chaos.”

RBT Competency Assessment Domains

The Competency Assessment is built around the RBT Task List — 20 skills the BACB wants to make sure you can actually do, not just memorize.

Here’s the rundown of what you’ll be expected to demonstrate or talk through:

Measurement

• Collecting continuous data (like frequency or duration)
• Using discontinuous measurement (like interval recording)
• Entering and graphing data

Assessment

• Running a preference assessment
• Collecting ABC data

Skill Acquisition & Behavior Reduction

• Discrete-trial teaching
• Naturalistic teaching
• Chaining
• Prompting and prompt fading
• Stimulus control transfer
• Antecedent interventions
• Differential reinforcement
• Extinction procedures

Documentation & Reporting

• Writing objective session notes

Professional Conduct

• Maintaining client dignity
• Setting and respecting professional boundaries

Supervision

• Understanding BACB supervision expectations
• Identifying when to contact your supervisor for direction

Some of this you’ll do with a real client; some you’ll role-play or just explain.

But the goal is the same it is to show that you’re ready to handle the basics in a safe, ethical, and competent way.

Step-by-Step Guide to the RBT Competency Assessment

1. Finish Your 40-Hour RBT Training

Your coursework gives you the foundation for everything on the assessment. Review your notes and make sure you understand the basics — these skills will show up again on assessment day.

Don’t stress, cause nobody remembers every detail the first time.

Rewatch a video, reread a module, whatever helps. You’re not supposed to be perfect yet, just solid on the basics.

2. Choose a Qualified Assessor

Only an active BCBA or BCaBA can administer and sign off on your assessment. Most candidates complete this step through their employer, training provider, or supervisor.

If you’re unsure, just ask, totally normal question. No one expects you to magically know who’s certified.

3. Learn How the Assessment Works

It’s usually a mix of:

• Observation (performing skills with a client)
• Role-play (simulated scenarios with your assessor)
• Interview (verbal explanations of procedures and ethics)

Once you understand that it’s not some mysterious exam hiding in the shadows, the nerves drop way down.

It’s really just someone making sure you’re not winging it.

4. Review Each Task on the RBT Task List

Go domain by domain. Don’t just skim it, actually practice.

Run mock sessions, pretend you’re collecting data on your roommate’s habits (kidding… sort of), or walk yourself through scenarios out loud.

It doesn’t need to be fancy, just hands-on enough that you feel comfortable.

5. Complete the Competency Assessment

When you’re actually doing it:

• breathe
• follow the client’s plan
• don’t rush
• Ask for clarification if you need it. It’s not a trap
• Use professional language (translation: don’t say things like “yeah, so the kid freaked out”)

Your assessor genuinely wants you to pass. If something isn’t perfect, they’ll guide you, not punish you. The whole thing is way more “supportive supervisor checking your skills” than “terrifying final boss.”

You totally got this. It’s way less scary once you walk through it step by step.

What to Expect on Assessment Day

1. Format

This isn’t a sit-down-and-fill-in-bubbles kind of thing, it’s hands-on.

You’ll actually be doing ABA skills you’ve learned, not guessing answers.

And honestly? That’s a good thing.

Most people find it way easier to show what they can do than to remember exact wording from a textbook. You’ve practiced this, trust yourself.

The evaluation is hands-on. You’ll be demonstrating real ABA skills, not answering test questions.

2. Time Commitment

Most assessments take 1–3 hours, depending on the setting and the number of tasks completed with a client.

It goes by faster than you’d think.

Take your time, breathe, and remember: no one’s rushing you.

Your assessor wants you to feel comfortable, not pressured.

3. Location

You might do your assessment:

• in a clinic,
• in a client’s home,
• in a school,
• or even over live video (totally legit if approved).

Wherever it takes place, your assessor will make sure you know what’s going on and what’s expected.

You’re not walking into anything blind; they want you to feel prepared.

4. Client Involvement

At least three of the tasks need to be done with an actual client.

Don’t worry, your assessor will set everything up and tell you exactly what you’ll be doing.

If you feel nervous, that’s completely normal. Everyone does.

Just remember that you’re not being judged on perfection, you’re being guided and supported.

Passing Criteria

You need to show you can competently do all 20 tasks.

If you don’t nail something the first time, that’s okay.

Anything marked “needs more work” can be retaken later. No penalties, no shame, no limit on attempts.

Seriously, so many RBTs needed a redo on one or two tasks. It doesn’t mean you’re failing; it means you’re learning. You’re absolutely capable of this, and your assessor is there to help you succeed, not to catch you messing up.

How to Study for the RBT Competency Assessment

1. Use the Official BACB Materials

Honestly, the BACB stuff is your North Star here.

The RBT Task List, the Competency Assessment Packet, the Handbook, and your training notes?

That’s literally the exact blueprint your assessor will follow. Don’t waste time Googling random “study guides” and none of them were as clean or accurate as the real BACB documents.

Stick to the source; it helps so much.

Your best study guides are:

• RBT Task List
• RBT Competency Assessment Packet
• RBT Handbook
• Notes from your 40-hour training

2. Practice Actively

Don’t just read about DTT, run a quick mock trial. Don’t just review data types, actually practice interval recording using a 30-second clip from YouTube.

I even dragged my roommate into helping me role-play ethical scenarios (they took it way too seriously, but hey, I passed).

Point is: your muscle memory kicks in on assessment day, which is HUGE for calming nerves.

Instead of just reading:

• Try running a mock DTT trial
• Practice collecting interval data on a short video clip
• Set up a sample preference assessment
• Write mock session notes
• Role-play ethical scenarios

3. Get Comfortable with Documentation

This one catches a lot of people off guard.

Writing objective session notes sounds simple… until you try to do it without slipping into “he seemed upset” or “she looked bored.”

Practice writing in pure observable language:

• “The client cried for 45 seconds.”
• “Client independently completed 3/5 trials.”

Stuff like that. Your assessor will love you for it.

4. Work Through Challenging Skills

No shame here, chaining, prompting, and differential reinforcement tripped me up at first, too. If something still feels fuzzy, ask your supervisor for one more walkthrough.

They expect questions. They want you to get it right.

And honestly, the more comfortable you are explaining why you’re using a prompt or when you’d use DRA vs DRO, the smoother your assessment will feel.

5. Prepare Mentally

I promise: nerves are 100% normal.

Everybody walks in thinking they’re going to forget everything.

But once you start the first task, you get into a groove.

My Personal Take on RBT Competency Assessment?

Here’s my two cents: it’s really not as scary as it sounds.

The whole point is just to make sure you can do the stuff you’ve been learning safely and correctly. If you’ve done your 40-hour training and practiced even a little, you’re already way ahead.

Honestly, nerves are normal. I was sweating a bit, too, but your assessor isn’t there to fail you. They literally want you to succeed.

Take your time, ask questions if something’s unclear, and remember, if a task doesn’t go perfectly, it’s not the end of the world. You can retake anything marked “needs more work.”

So yeah, breathe, trust yourself, and go show off the skills you’ve been working on. You’ve got this.

Seriously.
