How many questions are on the RBT exam and how long do I get?

85 multiple-choice questions in 90 minutes. 75 are scored and 10 are unscored pilot questions mixed in. You will not know which are which, so answer every one as if it counts.

Do I find out if I passed right away?

You usually leave the center knowing how it went, and the official result is posted to your BACB account shortly after. The score you get is pass or fail, not a percentage.

Can I take the RBT exam online from home?

No. The BACB ended remote testing in September 2023. The exam is delivered in person only, at a Pearson VUE testing center, so you book a seat at a location near you.

The format, so there are no surprises

The exam is 85 multiple-choice questions and you get 90 minutes. Of those 85, only 75 are scored. The other 10 are pilot questions the BACB is trying out for future versions, and they are scattered in without any label. The practical takeaway is simple: treat every question as real, because you cannot tell the difference anyway.

Ninety minutes for 85 questions works out to a little over a minute each. That is a steady pace, not a relaxed one. You have time to read carefully, but not time to agonize. If a question stalls you, flag it and move on. Coming back with fresh eyes beats burning four minutes on one item.

The content follows the BACB RBT Test Content Outline (3rd edition), organized into six domains. If you have been practicing against that outline, nothing on the screen should feel like it came from nowhere.

It is in person, at a test center

This trips people up, so it is worth being plain about: there is no at-home option. The BACB ended remote testing in September 2023, so the exam is delivered only at Pearson VUE testing centers. You book a seat at one near you when the BACB authorizes you to schedule.

Look up your test center ahead of time. Know how long the drive is, where you park, and how check-in works at that location. Plan to arrive early. Showing up rushed is a bad way to start a timed exam, and arriving too late can cost you the appointment entirely.

What to bring, and what to leave

Bring a valid, government-issued photo ID. The name on it has to match the name on your BACB registration, so check that the day before, not in the parking lot. If they do not match, you can be turned away.

Leave everything else in the car or expect to lock it up. Test centers do not let you bring phones, notes, smartwatches, bags, or food to your seat. Most provide a small locker for your belongings. You will typically go through a quick check-in: ID verification, a photo, sometimes a palm scan, and a signature. It is routine. Thousands of people do it every week.

The center provides whatever you are allowed to use for scratch work, usually a small whiteboard or laminated sheet. You do not bring your own paper.

During the exam

You start with a short on-screen tutorial that does not count against your 90 minutes, so use it to get comfortable with the interface: how to flag a question, how to move forward and back, how to review flagged items at the end.

Then it is just you and the questions. Read each one fully before looking at the answers. The RBT exam likes to test whether you can apply a concept to a short scenario, not just define it, so the right answer is often the one that fits what a technician would actually do in that situation. When two options look close, the distinction is usually in the details of the question stem. Slow down and reread it.

Watch the clock, but do not let it run you. A good rhythm is to check your progress around the halfway mark. If you are roughly through 40 questions at the 45-minute point, you are fine.

When you find out

This is the part people most want to know, and the news is good: you usually do not wait long. Most candidates leave the center with an unofficial result, and the official outcome posts to your BACB account shortly after. The result is pass or fail. There is no percentage score to interpret and nothing to read into beyond the outcome.

If you pass, you move on to the rest of the credentialing process and your supervised work. If you do not, you are allowed to retake it, and you will have a much better sense of where you stand the second time.

The night before

Do not cram. By exam day the studying is either done or it is not, and a panicked late-night review tends to shake your confidence more than it helps. Get your ID out, confirm the address, set out what you are bringing, and sleep. A rested brain reads scenario questions far better than a tired one that crammed until midnight.
