RBT practice exam questions people ask

Is this RBT practice exam free?: Yes. You can play 3 five-question rounds a day without an account. A free account adds more practice sessions each month, progress tracking and a timed full-length mock.
How many questions are on the RBT exam?: The RBT exam (3rd edition outline) has 85 multiple-choice questions: 75 scored and 10 unscored pilot questions. You have 90 minutes. Check the BACB's RBT Handbook before you test, since details can change.
What is on the RBT exam?: Questions follow the BACB's RBT Test Content Outline: data collection and graphing, behavior assessment, behavior acquisition, behavior reduction, documentation and reporting, and ethics. Our questions are tagged to those same tasks.
How should I study for the RBT exam?: Practice applying concepts to real session scenarios, not just memorizing definitions. Read the feedback on every question you miss, revisit those topics, then try a timed mock exam closer to test day.
Are these real RBT exam questions?: No. These are original practice questions written to match the outline. Real exam questions are confidential.
Is there a full-length RBT mock exam?: Yes. With a free account, the Practice Lab has a timed RBT mock that matches the real question count and time limit, with results broken down by domain.

Practice only — not an official BACB result or competency determination. Questions are original practice items, not real exam questions.
