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. During a family gathering, a behavior analyst observes a client’s father, Abe, immediately reacting to trash being discarded on the floor. Specifically, Abe’s wife throws a piece of wrapping paper on the ground, and within 4 seconds, Abe bends down to pick it up. The behavior analyst is interested in the time elapsed between the wrapping paper hitting the ground (as a discriminative stimulus) and Abe initiating the action of picking it up (as the response). What dimension of behavior is the behavior analyst measuring in this scenario?

Duration

Rate

Latency

Interresponse Time (IRT)

Latency is defined as the measure of the time elapsed between the onset of a stimulus SD and the initiation of a response In this scenario the SD is the wrapping paper hitting the ground and the response is Abe beginning to pick it up The 4second interval precisely fits the definition of latency as it is the time from the signal trash on the ground to the start of the action Duration would measure how long Abe spends picking up the trash or how long the behavior itself lasts from start to finish Rate or frequency would measure the number of times Abe picks up trash within a specific observation period Interresponse Time IRT would measure the time between the end of one response and the beginning of the next identical response eg the time between Abe finishing picking up one piece of trash and starting to pick up another piece Since the scenario focuses on the time from stimulus onset to response initiation latency is the correct dimension of behavior being measured
