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. As a BCBA, you are designing a behavior intervention plan for a client who frequently engages in disruptive vocalizations during group activities. To accurately measure the temporal relationship between the onset of the group activity and the first vocalization, and also the time between successive vocalizations, which fundamental dimension of measurement should you focus on?

A) Repeatability

B) Temporal Extent

C) Temporal Locus

D) Duration

Temporal locus refers to the point in time at which a behavior occurs This dimension of measurement is concerned with when behavior occurs relative to other events The question specifically asks about the temporal relationship between the onset of the group activity and the first vocalization which is latency and the time between successive vocalizations which is interresponse time or IRT Both latency and IRT are measures derived from temporal locus Repeatability A refers to instances of a behavior occurring repeatedly over time from which count and frequency are derived Temporal Extent B refers to the time a behavior occupies from which duration is derived Duration D is a specific type of measurement under temporal extent measuring how long a behavior lasts which is not the focus of this question
