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. During RBT training, Linda shows her trainees a video of a client working on a worksheet. She provides a clear operational definition for ‘off-task behavior’ as ‘doing something other than working on the worksheet for more than 10 seconds straight’ and instructs the trainees to record the number of times this behavior occurs. After viewing, Trainee 1 records 4 instances, Trainee 2 records 3 instances, and Trainee 3 records 2 instances. Given these discrepancies, what crucial quality of the measurement collected by the trainees is inherently lacking?
Interobserver Agreement IOA refers to the degree to which two or more independent observers report the same observed values after measuring the same events In this scenario multiple observers trainees witnessed the same event the video of the client and were instructed to measure the same behavior offtask behavior using the same operational definition However their recorded frequencies differ significantly 4 3 and 2 instances This inconsistency directly indicates a lack of Interobserver Agreement While a lack of IOA often suggests potential issues with the measurements accuracy or the operational definition IOA itself is a direct measure of the reliability or consistency of the measurement procedure and observer performance Poor IOA means that the data collected may not be reliable or trustworthy making it difficult to confidently make decisions based on it Accuracy refers to how close the measured value is to the true value without a true value established by an expert we cant definitively determine accuracy though its likely impacted by poor IOA Validity refers to whether the measurement system actually measures what it purports to measure Reactivity refers to the phenomenon where the act of observing influences the behavior being observed which is not applicable to observers recording from a video
