Free RBT Study Guide — Task List 3rd Edition

Six sections, one for each domain of the RBT Test Content Outline (3rd Edition). Each one covers the concepts the exam actually tests, names the mistakes that cost candidates marks, and ends with its own quiz so you can check whether it stuck. About 135 minutes of reading in total, free and with no sign-up.

Aligned to the RBT Task List 3rd Edition (effective 1 January 2026) · Last content review: August 2026 · How we write our questions

The six domains

Sections are ordered A–F. If you are short on time, the weight column tells you where the marks are: Behavior Acquisition alone is roughly a quarter of the exam.

How the exam is weighted

The RBT exam delivers 85 questions in 90 minutes, of which 75 are scored. Those 75 are distributed across the six domains as follows — worth knowing before you decide what to revise.

The real exam delivers 85 questions in 90 minutes: 75 scored plus 10 unscored pilot questions that do not count toward your result.

A study loop that works

  1. Take the 85-question exam in Exam Mode for a baseline and a per-domain breakdown.
  2. Read the study guide section for your weakest domain.
  3. Take that domain’s section quiz in Study Mode, reading every explanation.
  4. Take a different full-length version and compare the per-domain numbers.

Repeating that loop beats retaking the same exam, which measures how well you remember the questions rather than how well you know the content.

Frequently asked questions

What is the RBT Task List 3rd Edition, and what changed?
The BACB replaced the RBT Task List 2nd Edition with the RBT Test Content Outline (3rd Edition), effective for exams from 1 January 2026. Four of the six domain names changed — Measurement became Data Collection and Graphing, Skill Acquisition became Behavior Acquisition, Assessment became Behavior Assessment, and Professional Conduct and Scope of Practice became Ethics. The task count grew from 37 to 43, with new emphasis on data accuracy and on cultural humility. The weighting shifted too: the old Skill Acquisition domain was around 32% of the exam, while Behavior Acquisition is about 25%.
What score do you need to pass the RBT exam?
There is no fixed percentage. The BACB uses scaled scoring, which converts your raw score to a scaled score to account for small differences in difficulty between exam forms, and it does not publish a percentage pass mark. Many candidates use 80% on full-length practice exams as a personal readiness benchmark, but that is a study target people set for themselves — not the pass mark, and no practice site can tell you the number you need.
What is the difference between the RBT competency assessment and the RBT exam?
They are two separate requirements. The Initial Competency Assessment is conducted in person by a qualified assessor who watches you perform tasks with a client or a role-play participant, and it must be completed before you can sit the exam. The exam itself is a written multiple-choice test taken at a Pearson VUE centre. Passing one does not substitute for the other, and both must be completed for certification.
How should I use this site to prepare?
Take one full-length exam in Exam Mode first to get a baseline and a per-domain breakdown. Use the weakest-domain result to pick a section quiz and the matching study guide section, work through those, then take a different full-length version. Repeating that loop is more effective than taking the same exam repeatedly, which measures memory of the questions rather than knowledge of the content.
