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!

 

Results

#1. A BCBA is implementing an intervention for a client who engages in repetitive hand-flapping, which is interfering with their participation in learning activities. To address this, the BCBA places their hand gently but firmly in front of the client’s hand each time the client initiates the hand-flapping motion, physically preventing the behavior from occurring. The BCBA ensures that the client is not harmed and that the intervention is implemented consistently. This procedure aims to decrease the frequency of hand-flapping. What type of behavioral intervention does this best represent?

Extinction

Negative Reinforcement

Positive Punishment

Negative Punishment

Response blocking is a procedure where a physical intervention restraint or force is used to prevent the occurrence of a target behavior By physically blocking the handflapping something is added to the environment the BCBAs handphysical impedance immediately following the initiation of the behavior with the goal of decreasing the future likelihood of that behavior This fits the definition of positive punishment adding a stimulus to decrease behavior It is not extinction because extinction involves withholding reinforcement for a previously reinforced behavior which requires the behavior to occur response blocking prevents the behavior from occurring It is not negative reinforcement which increases behavior by removing an aversive stimulus nor negative punishment which decreases behavior by removing a desired stimulus
