Getting ready for your BCBA exam? You’re in the right place.

I created RBTExamPrep.com to give you the most realistic BCBA mock exam experience possible 185 questions designed to feel just like the real thing.

My goal isn’t just to help you pass, but to help you understand every concept deeply.
Whether you get a question right or wrong, you’ll see detailed feedback explaining why, so you’ll be ready for that type next time. I want you to walk into test day feeling confident, calm, and prepared.

Many students have shared that these questions felt almost identical to the real exam and that’s exactly what I was aiming for. I’d love to hear how you did please share your score in the comments below! It really helps encourage others who are preparing for the exam. 🙂

I built this site to keep high-quality BCBA prep resources free and accessible for everyone, which is why it’s supported by ads. If it helped you, it’d mean a lot if you shared it with your peers.

If you want to keep practicing, check out the BCBA section for more tests and study materials!

#1. A Board Certified Behavior Analyst (BCBA) is working with a new client and needs to establish a definitive hierarchy of the client’s preferred items to effectively structure reinforcement schedules. The BCBA has identified approximately 40 potential reinforcers. Which of the following preference assessment methods would be most effective and efficient for accurately establishing a clear, ranked order of these items from most to least preferred?

Single Stimulus Preference Assessment

Multiple Stimulus Without Replacement Preference Assessment

Paired Stimulus (Forced Choice) Preference Assessment

Multiple Stimulus With Replacement Preference Assessment

To establish a definitive hierarchy where each items preference level is directly compared against others the Paired Stimulus also known as Forced Choice preference assessment is the most effective method In this assessment every item is paired with every other item in a systematic manner allowing for a comprehensive comparison and a clear ranking of preferences Single stimulus assessments only identify whether an item is preferred or not without direct comparison Multiple stimulus with replacement and without replacement assessments can identify a top few preferred items or a general order of selection but they do not provide the exhaustive direct comparisons necessary for a robust detailed hierarchy in the same way Paired Stimulus does The text explicitly states if you want to establish an actual hierarchy the best way to do it is a paired Choice assessment
