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.

#1. Martha, a BCBA, is developing a token economy system for her students. She has diligently conducted preference assessments to identify items and activities her students are interested in. Based on the results of these assessments, she has designed the physical tokens and selected a variety of potential backup stimuli. Considering these initial steps, what is the most crucial next step Martha needs to take to ensure her token economy is truly effective?
The text highlights a critical distinction in ABA Shes only done a preference assessment so she only knows what they like Does that mean its going to be reinforcing Absolutely not And tokens are only as powerful as their backup reinforcers So in order to make sure Marthurs economy is effective were going to need to start identifying some reinforcement A preference assessment identifies stimuli a learner prefers but it does not confirm that those stimuli will function as reinforcers ie increase future behavior To ensure the token economy is effective Martha must conduct reinforcer assessments eg invivo tests progressive ratio schedules to determine if the selected backup stimuli actually increase the desired behavior when delivered contingently While pairing tokens with praise option D is an excellent practice for establishing praise as a generalized conditioned reinforcer GCR and including a response cost option A is a common though not mandatory component of some token economies neither is as fundamental to the effectiveness of the entire system as ensuring the backup stimuli are true reinforcers Implementing a punishment procedure option B is not a necessary or inherent component for an effective token economy token economies primarily rely on positive reinforcement
