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. Chad plays baseball for his local men’s league team. For one game, the entire team is required to wear colored wristbands provided by a sponsor. Chad finds wearing the wristband to be highly unpleasant due to its texture and tightness. During the game, he repeatedly pulls off and removes the wristband from his wrist. Each time he removes the wristband, he experiences an immediate sensation of relief from the discomfort. Consequently, Chad’s behavior of removing the wristband during games increases in frequency, as he is motivated to escape or avoid the unpleasant sensation. In this scenario, what is the most appropriate description of the wristband’s function relative to Chad’s behavior of removing it?
This scenario perfectly illustrates negative reinforcement Negative reinforcement occurs when the removal or avoidance of an aversive unpleasant stimulus following a behavior leads to an increase in the future probability of that behavior 1 Behavior Chad removing the wristband 2 Aversive Stimulus The unpleasant sensation caused by wearing the wristband 3 RemovalEscape By removing the wristband Chad escapes the unpleasant sensation 4 Effect on Behavior The frequency of Chad removing the wristband increases Therefore the wristband functions as an aversive stimulus whose removal negatively reinforces the behavior of taking it off Option A is incorrect because the behavior removing the wristband is increasing not decreasing which rules out punishment While the wristband is an antecedent to Chads behavior option B is too general and doesnt capture the reinforcement contingency Option D is incorrect because a discriminative stimulus Sd signals the availability of reinforcement for a particular behavior here the wristband itself is the aversive event that occasions the escape behavior not a signal for positive reinforcement
