About RBT Mock Exams

How the questions are written

Every question tests one of the 43 tasks in the BACB's RBT Test Content Outline (3rd ed.), the outline the exam has followed since 1 January 2026, and each one is tagged with its task. The questions use the exam's format: a short scenario or definition, four options and one correct answer. Ethics questions follow the RBT Ethics Code (2.0).

Each question is written for this site and then checked in a separate review pass against the outline and the Ethics Code: that the keyed answer is the single best one, that every other option is wrong for a clear reason, and that the explanation matches.

How the exams are built

The 85-question practice exam and the75-question mock exam give each of the 6 domains the same share of questions as the real exam, drawn fresh from the whole bank on every attempt. The domain quizzes draw 20 questions from one domain at a time.
