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.

#1. Jenny needs to gather information on how frequently her son’s daycare takes him to the bathroom throughout each day. She wants to identify the most useful and specific dimensional quantity to accurately track this behavior over time, allowing for comparisons across different days or weeks. Considering the core dimensional quantities of behavior, which measure would be most appropriate for Jenny’s objective?
Jennys objective is to determine how often her son goes to the bathroom each day which inherently includes a temporal component While frequency a simple count of occurrences is a measure of repeatability rate is a more precise and often more useful dimensional quantity when a specific time component is involved Rate is defined as the number of responses or occurrences of a behavior per unit of time eg responses per minute per hour or per day By expressing the bathroom trips as times per day Jenny obtains a rate This measure is superior to simple frequency in this context because it standardizes the count by the observation period allowing for meaningful comparisons eg he went 6 times per day on Monday but 4 times per day on Tuesday Without the time component frequency alone eg six times would lack context Duration measures the total time an event occurs and latency measures the time between a stimulus and the onset of a response neither of these directly addresses how often per day within a specified period
