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 Board Certified Behavior Analyst (BCBA) is working with a client who frequently engages in repetitive hand-flapping. The BCBA is primarily concerned with understanding the onset of these behaviors in relation to specific environmental triggers. Therefore, the BCBA decides to record the time from the presentation of a trigger (e.g., a novel stimulus) to the initiation of hand-flapping. Which fundamental dimensional quantity of behavior is the BCBA primarily focused on measuring in this scenario?

Repeatability

Temporal Extent

Temporal Locus

Rate

Temporal Locus is one of the three fundamental dimensional quantities of behavior along with repeatability and temporal extent It refers to the point in time at which a behavior occurs Derivatives of temporal locus include latency the time from the onset of a stimulus to the initiation of a response which is precisely what the BCBA is measuring here and interresponse time IRT the time between two consecutive responses Repeatability refers to the fact that a behavior can be counted or occurs repeatedly over time eg frequency count rate Temporal extent refers to the duration of a behavior how long it lasts Rate is a derivative of repeatability specifically count per unit of time not a fundamental dimensional quantity itself
