BT Exam Practice

The RBT exam is getting close, the study guide is read, and what you really want is to sit down with questions and find out where you stand. BT Exam Practice puts a full 85-question mock exam, six domain quizzes and a 20-question quick check on the open web with no sign-up. The mock has an optional 90-minute timer, and every question explains why the right answer is right and why each wrong option is wrong.

The questions follow the 2026 Test Content Outline. According to the about page, there are 1,016 original questions, written with AI from the site's own concept library, answered blind by three other AI models and human-verified before they go live. None uses real exam content.

The RBT competency assessment isn't a written test. An assessor watches you perform the tasks on the BACB's form and signs off. The site's checklist page turns that into a 20-item preparation list, organised by the six domains of the outline. It also covers where the assessment sits in the timeline and how renewal works in 2026.

The page is careful about its limits, which is good to see. It treats the official BACB form as the source of truth, and calls its own checklist a plain-language list for practice and not a copy of that form.

The Study plan costs $49 one time and adds drills by domain and more full-length mocks. The site says it's fully refunded if you finish at least one of the plan's mocks and don't pass.

The plan includes an AI coach. Under the privacy policy, last updated November 10, 2026, the coach sends the practice question and your messages to Anthropic and OpenAI, which delete them within 30 days. The policy warns you not to type client names or health details, and that's advice worth following.

The operator is Tianshu Labs LLC, a Wyoming company. BT Exam Practice is independent and not affiliated with the BACB, so a good practice score is a study signal and nothing more. If you're preparing for the RBT exam, the free mock is an easy first evening of study.
