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. A Board Certified Behavior Analyst (BCBA) is reviewing six-month data reports for clients under their supervision. They notice a consistent trend across several technicians during and immediately following the BCBA’s direct supervision sessions, client maladaptive behaviors tend to increase, and the duration of client engagement in preferred break time activities tends to decrease. Given this observation, what is the most likely and best explanation for these changes in client behavior?
Reactivity refers to the phenomenon where the act of observing or being observed changes the behavior of the individual being observed In this scenario the consistent change in client behavior increased maladaptive behavior decreased preferred activity engagement specifically during and right after the supervision sessions directly points to the supervisors presence as the influential factor The clients or potentially the technicians but the question focuses on client behavior are reacting to being observed by the BCBA Observer drift A relates to changes in how behavior is measured not necessarily changes in the behavior itself Treatment drift B refers to unintended changes in the implementation of an intervention by the technician which could be a factor but reactivity more broadly explains why the behavior changes in the presence of the observer encompassing client or technician responses to observation Random chance D is generally not the best explanation when a clear pattern related to a specific variable supervisors presence is observed
