Questions about tests & quizzes
Clear answers before you begin.
How many questions are on the RBT exam?
The BACB RBT exam has 85 multiple-choice questions and a 90-minute limit. Of those questions, 75 are scored and 10 are unscored. Our full-length practice forms also contain 85 questions and offer a 90-minute timer.
Is the full RBT mock exam free?
A free account includes one 20-question sample test. The paid Practice plan includes 20-, 50-, and 85-question tests, with four test attempts per monthly billing period. No purchase is required to create a free account.
Can I take a test without a timer?
Yes. Timed and untimed modes support different goals: pacing rehearsal or slower learning and review.
Is a MeridianBx test score an official prediction?
No. It is a practice result intended to guide review, not an official BACB score or a guarantee of passing.
