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 driver is traveling significantly above the posted speed limit on a highway. As the driver approaches an exit, they observe a police car parked on the shoulder with its lights off. Upon seeing the police car, the driver immediately reduces their speed to below the legal limit. In this specific scenario, what does the presence of the police car primarily function as for the driver’s speeding behavior?

An S-delta (S) for speeding.

A discriminative stimulus (SD) for reinforcement of slowing down.

A discriminative stimulus (SD) for punishment.

A punisher.

A discriminative stimulus SD for punishment is an antecedent stimulus that signals that a particular behavior if emitted will be followed by a punishing consequence In this example the police car serves as an SD for punishment because its presence signals that speeding the behavior is now highly likely to be followed by an aversive consequence such as a traffic ticket or other legal penalties This increased likelihood of punishment is what causes the driver to reduce their speed It is not an Sdelta A because an Sdelta signals that reinforcement or punishment is unavailable While slowing down might lead to avoiding punishment which is a form of negative reinforcement the police cars direct function related to the speeding behavior is to signal the availability of punishment C not primarily to signal reinforcement for slowing down B Furthermore the police car is an antecedent stimulus not a consequence so it cannot be a punisher D
