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 10-year-old client, who has no documented history of physical aggression or self-injurious behavior, begins to frequently elope from the classroom. To address this, the teacher, under the guidance of a consultant, implements a response cost procedure where the client loses 5 minutes of recess for each instance of elopement. After approximately one week of this intervention, the client begins hitting peers during unstructured play times, a behavior that was never observed prior to the implementation of the response cost. What is the most parsimonious explanation for the client’s newly observed aggressive behavior?
The scenario presents a clear case where a new undesirable behavior hitting peers emerges directly after the implementation of a punishment procedure response cost for a different target behavior elopement in a client with no prior history of the new behavior Punishmentinduced aggression is a welldocumented side effect of punishment procedures where an individual may react aggressively to the aversive stimulus or the procedure itself Given the clients lack of prior aggression this explanation is the most parsimonious simplest and most likely and directly aligns with the observed sequence of events Option A is less likely as theres no information to suggest negative reinforcement is maintaining the aggression especially as its a novel behavior Option B speculates about the increase of elopement for which we have no data and resistance is not a primary behavioral explanation for the emergence of a new behavior Option D spontaneous recovery refers to the reemergence of an extinguished behavior but the text explicitly states the client had no documented history of aggression meaning it was not a previously extinguished behavior
