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 BCBA is designing a data collection system for a client’s repetitive vocal stereotypy. They are considering various continuous measurement procedures that directly capture the quantifiable dimensions of behavior. Based on the fundamental properties of behavior, which of the following is NOT considered a direct measure of repeatability?

A) Count

B) Rate

C) Acceleration

D) Interresponse Time (IRT)

The three fundamental dimensional quantities of behavior that can be measured directly are repeatability temporal extent and temporal locus Repeatability refers to the fact that behavior can be counted and reoccur Measures of repeatability include count the number of occurrences of a behavior rate count per unit of time and acceleration the change in rate over time Temporal extent refers to the duration of a behavior or how long it occurs Temporal locus refers to when a behavior occurs in relation to other events and its measures include latency the time from a stimulus to the onset of a behavior and interresponse time IRT the time between two consecutive instances of a response The text clearly distinguishes these stating repeatability has to do with things like frequency rate count and of course acceleration and temporal locus has to do with irt and latency Therefore IRT is a measure of temporal locus not repeatability
