This page explains how the practice questions on Free RBT Practice are built, what they are based on, and where their limits are. Last updated October 3, 2026.
Content alignment
The questions are organized around the BACB RBT Test Content Outline (3rd edition), the official document the exam is built from. The outline has six content areas and 43 tasks. Each question here is tagged to the task it practices, so you can see which parts of the outline a question covers. For a plain-language walkthrough of the outline, see our RBT test content outline guide.
The question bank
The bank contains 300 questions, 50 in each of the six content areas. Each question is multiple choice with four options, a difficulty label (easy, medium or hard), and a written explanation of the correct answer. The questions were written for this site. They are not copied from the BACB, from the real exam, or from other websites.
How the full practice exam is built
The 85-question practice exam draws questions from each content area in the same proportions as the official outline, then randomizes the questions within each area. The answer options are also balanced so that the correct answer is not more likely to appear in any one position.
| Content area | Share of exam | Scored questions on exam | Our bank |
|---|---|---|---|
| Data Collection and Graphing | 17% | 13 | 55 tagged, 50 total |
| Behavior Assessment | 11% | 8 | 46 tagged, 50 total |
| Behavior Acquisition | 25% | 19 | 44 tagged, 50 total |
| Behavior Reduction | 19% | 14 | 48 tagged, 50 total |
| Documentation and Reporting | 13% | 10 | 42 tagged, 50 total |
| Ethics | 15% | 11 | 60 tagged, 50 total |
The real exam has 85 questions, of which 75 are scored. The scored counts above are from the BACB outline.
Coverage by task
This table shows how many questions practice each task. Coverage is not perfectly even: some tasks, such as conditioned reinforcers (C.2), have only a few questions, while others, such as functional assessment (B.3) and objective session notes (E.4), have many more. A small number of vocabulary questions, such as defining a mand or a tact, support the tasks but are not tied to one specific task. We are adding questions to the thinner tasks over time.

Difficulty and explanations
Easy questions test recall of a definition or a basic procedure. Medium questions ask you to apply a concept in a short scenario. Hard questions ask you to choose between options that are all plausible on their face. Every question has an explanation so you can learn why the answer is correct, not just whether you got it right.
Limits and disclaimers
Free RBT Practice is not affiliated with or endorsed by the BACB. The questions are practice aids, not official exam content, and they have not been reviewed by a Board Certified Behavior Analyst. Passing the practice questions does not guarantee a passing result on the real exam. Certification requirements and exam content can change, so always check the current BACB RBT requirements before you apply or test. See also our editorial policy.
