Questions about practice tests
How many questions are on the RBT exam?

A free account includes one 20-question sample test. The Practice plan includes 20-, 50-, and 85-question tests, with 4 practice tests each month. The 40-hour course includes 30 days of Practice after you finish.
Can I take a test without a timer?
Yes. Use untimed mode while you’re learning and timed mode when you want to practice your pace.
Does my practice test score predict my real exam score?
No. It’s a practice result to help you decide what to review. It isn’t an official BACB score or a guarantee that you’ll pass.
