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) instructs a Registered Behavior Technician (RBT) to collect partial interval data on a client’s screaming behavior. The interval duration is set at 25 seconds. During the observation, the client screams for 2 seconds at the 24-second mark within the first interval. In the second interval, the client screams briefly at the 15-second mark. In the third interval, the client emits a scream at the 5-second mark. For all three consecutive intervals, the behavior occurred at some point. Based on these observations, how many responses should the RBT record?

Not enough information to determine

Partial interval recording involves recording if the behavior occurs at any point during the designated interval regardless of its duration or how many times it occurs within that interval If the behavior occurs even once for a brief moment within an interval that interval is scored as an occurrence In this scenario the client screamed at some point during the first interval at 24 seconds the second interval at 15 seconds and the third interval at 5 seconds Since the behavior occurred in all three consecutive intervals the RBT should record 3 responses one for each interval where the behavior was observed The specific timing or duration within the interval does not change the scoring for partial interval recording only its presence or absence
