How Our RBT Practice Questions Are Made
Free does not have to mean careless. Here is what goes into every quiz and exam on this site.
Every question is written for a task in the BACB RBT Test Content Outline (3rd ed.), and the full exam covers all six domains.
Most questions are short situations from ABA sessions, because that is how the real exam asks them. Plain definitions alone will not prepare you.
You see your score and every correct answer after you finish, not while you answer, so each RBT practice exam feels like test day.
Rules on supervision, retakes and exam format are checked against the RBT Handbook. Pages are reviewed whenever the BACB updates its requirements.
RBT Exam Prep FAQs
Quick answers before you start.
Is this RBT practice exam really free?
Yes. The 85-question RBT practice exam, the 75-question scored set, all six domain quizzes and every study guide are free, with no sign-up.
How many questions are on the RBT exam in 2026?
85 multiple-choice questions in 90 minutes. 75 are scored and 10 are unscored pilot questions that look exactly like the others, so treat every question as if it counts.
Should I start with the full exam or the domain quizzes?
If the material is still new, start with the RBT study guide and one domain quiz at a time. If your test is close, take the full exam first to find your weak domains, then practice those.
Are these questions updated for the 3rd edition outline?
Yes. All quizzes, exams and guides follow the RBT Test Content Outline (3rd ed.), which the BACB uses for every RBT exam taken on or after January 1, 2026, including the new Data Collection and Graphing and expanded Ethics tasks.
When do I see the correct answers?
After you finish. Like a real test center, nothing is marked while you answer. Your results page then shows your score, each correct answer and what to study next.
Ready to see your score?
One full timed run tells you more than ten short quizzes.
