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 Registered Behavior Technician (RBT) observes a client, Sarah, repeatedly engaging in a hand-flapping behavior. When asked why Sarah flaps her hands, the RBT states, ‘She does it because she is anxious.’ Which of the following statements most accurately describes the RBT’s explanation in the context of Applied Behavior Analysis?

It is a valid functional explanation of the behavior.

It is an explanatory fiction, attributing the behavior to an unobservable internal state.

It is a descriptive statement, simply labeling the behavior.

It is a hypothetical construct that requires further scientific investigation.

An explanatory fiction occurs when a fictitious or hypothetical construct like anxiety in this case is offered as the cause of a behavior rather than identifying an observable manipulable environmental variable While Sarah might indeed feel anxious stating that she does it because she is anxious does not provide an explanation that allows for direct intervention In ABA we seek to identify environmental antecedents and consequences that occasion and maintain behavior rather than attributing it to internal states which are often simply other behaviors or descriptions of states The text illustrates this when it says were saying she likes the fireplace because of her nerves not because of the consequence of the past that is an explanatory fiction
