Methodology
Content alignment
Every question and study guide is built around the BACB RBT Test Content Outline (3rd ed., 2026), the official outline the BACB tests against, updated for the 2026 (3rd edition) exam. Each question carries a competency field (e.g. A-01, F-02) so you can study by domain and identify weak spots.
Question bank
The full bank contains 851 questions, and it's the heart of the study pack and the book:
- Topic question sets: focused, domain-by-domain practice (566 questions across 6 content areas)
- Quick reviews: three short mixed sets (30 questions) to run between content areas, each spanning all 6 domains
- Full practice exams: 3 simulations of 85 questions each (255 questions)
- A free 25-question sampler is on the site so you can try the question style before you buy.
Every question maps to one of the 43 official tasks on the BACB RBT Test Content Outline (3rd ed.), so the bank covers the whole blueprint.
The study guides are held to the same map. Each guide declares the tasks it teaches, and an automated check fails our build if the bank asks about a task no guide covers. That means the questions can't quietly drift ahead of the material, which is a real failure mode: it is how a study guide ends up asking you to thin a reinforcement schedule it never explained.
Difficulty calibration
Each question carries two labels, and they are separate things.
Difficulty is basic, intermediate, or advanced. Basic questions test recall of a definition or a procedure. Intermediate questions ask you to apply a concept in a clear context. Advanced questions ask you to choose between options that are all defensible on their face, which is where the real exam does most of its work.
Scenario is a separate flag: 355 of the 851 questions describe a realistic client interaction instead of asking you directly. Scenario questions run across all three difficulty levels, so a short case can still be a recall question and a hard question can still be asked plainly. The free sampler is drawn entirely from scenario questions, because that is the format the exam leans on hardest.
Explanations
Every question includes a substantive explanation, not just an answer letter. Explanations teach the underlying concept and call out why each distractor is wrong, so you learn from mistakes rather than just memorize answers.
Updates
Study guides show their last-updated date. This content is AI-assisted and cross-checked against standard ABA and the current BACB outline; it has not been formally reviewed by a board-certified analyst, and we say so plainly in our editorial policy.

Limitations and disclaimers
This site is a study resource, not a substitute for supervised practice or a BACB-approved 40-hour training program. Use it alongside official preparation. Passing our practice exams does not guarantee you will pass the real exam.
