RBT Practice Set: 25 Questions on the 2026 Outline

Why a 25-question practice set works

Big question banks are great, but they can also be paralyzing. A 1000-question bank is a library; a 25-question set is a workout. Twenty-five questions is long enough to touch every domain on the RBT exam and short enough to finish in one focused sitting, about 20 minutes if you work at real exam pace. That makes it the perfect daily rep: small enough that you actually do it, big enough that it tells you something real about where you stand.

Repetition with feedback is how the RBT exam is really passed. Reading notes feels productive, but the exam does not ask you to recite definitions. It gives you a scenario, like a client who just escalated, a supervisor who gave feedback, or a session note that needs a second look, and asks you what to do next. The only way to get good at those questions is to do lots of them, miss some, and read why. Every question below explains the correct answer and why the wrong answers are wrong, so each miss becomes a lesson instead of just a lost point.

This set is also mapped to the current exam. The BACB retired the 2nd edition RBT Task List on January 1, 2026, and the exam now follows the 3rd edition Test Content Outline. Older practice questions can drill outdated domain names, old weights, and ethics rules from the retired code. These 25 questions are built for the outline you will actually be tested on, so your study time points at the right target.

How to use this practice set

1. Answer honestly, like it is test day. Do not peek at the explanation before you commit to an answer. The point is to test your thinking, not to collect a perfect score.
2. Read every explanation, even for questions you got right. The explanations cover why the wrong answers are wrong, which is where the exam traps live. A right answer for the wrong reason is a question you will miss next time.
3. Watch your streak and your domain scores. The quiz tracks your streak as you answer and breaks down your accuracy by domain at the end. If one domain keeps sinking your score, that is your study assignment for tomorrow.
4. Download the PDF for offline reps. The printable version has all 25 questions with an answer key, which is handy for studying with a partner or for a no-screen review session.

Quick refresher: the 2026 RBT exam format

Here is what the real exam looks like, straight from the BACB RBT Handbook: 85 multiple-choice questions, 75 scored and 10 unscored pilot questions, with 90 minutes on the clock at a Pearson VUE testing center. You cannot tell the scored questions from the pilots, so every question counts. The exam is only offered in English, and results are reported as pass or fail at the testing center. The BACB does not publish a percentage cut score, so ignore the rumors and focus on covering the whole outline.

Before you can sit for the exam, you need to complete the 40-hour training, pass the Initial Competency Assessment with a qualified supervisor, and meet the rest of the eligibility requirements in the handbook. The practice below assumes you have that foundation. If you are still picking a training provider, start with our 40-hour training guide before you spend much time on practice questions.

The six domains covered in this set

The 3rd edition outline divides the 75 scored questions across six domains with published approximate weights. This practice set includes questions from all six, so your results map to the real blueprint:

• Behavior Acquisition (25%): reinforcement, prompting and fading, DTT, shaping, chaining, and generalization.
• Behavior Reduction (19%): functions of behavior, extinction, differential reinforcement, and antecedent interventions.
• Data Collection and Graphing (17%): continuous and discontinuous measurement systems and reading graphs.
• Ethics (15%): the RBT Ethics Code (2.0), boundaries, confidentiality, supervision, and scope of practice.
• Documentation and Reporting (13%): objective session notes, data reporting, and supervisor communication.
• Behavior Assessment (11%): ABC data, preference assessments, and assisting with functional behavior assessments.

You can read the official domain list on the BACB RBT page, which also links the current ethics code. When in doubt, the BACB documents win every argument.

How to read your score

Your score at the end is a snapshot, not a verdict. Aim for 80% or better on fresh practice material across several sets before you book the exam, because one good set can be luck. What matters more than the number is the pattern: if your misses cluster in one or two domains, those domains are your study plan for the next week. Retake this set after a few days of targeted review and watch the weak domains climb.
