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. A Board Certified Behavior Analyst (BCBA) is reviewing a client’s data on a line graph. The data path for a target behavior shows a clear pattern of deceleration, indicating a consistent decrease in the occurrence of the behavior over observation periods. When analyzing this graphical display, what specific dimension of behavior is the BCBA primarily describing?
Deceleration like acceleration refers to the overall direction or trajectory of the data path on a line graph When a data path is decelerating it indicates a decrease in the rate frequency or magnitude of the behavior over time thus describing the trend of the behavior Trend is the general direction of the data path whether increasing decreasing or zero flat Level refers to the value on the vertical axis around which a series of data points converge indicating the magnitude of the behavior Variability refers to the degree to which data points are dispersed around the trend line or their average value reflecting how consistent or inconsistent the behavior is Celeration is a specific type of trend that quantifies the change in rate over time often expressed as a multiplier eg rate doubled or halved per unit of time While deceleration can be thought of as a negative celeration trend is the more fundamental and encompassing descriptor of the overall direction of the data path which includes the concept of deceleration
