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. Juan, an aspiring clarinet player, wants to determine the optimal amount of daily practice time that will most effectively help him learn new songs. He has identified ‘practice’ as a crucial component. To achieve his goal, he plans to systematically vary his practice duration (e.g., 30 minutes on Monday, 60 minutes on Tuesday, 90 minutes on Wednesday) over several weeks while keeping other practice elements (e.g., type of exercises, instrument condition) constant. He will then track his learning progress for each duration. What type of experimental analysis is Juan conducting?
A Parametric Analysis is an experimental design strategy used to evaluate the effects of different values or levels of an independent variable on behavior Its primary goal is to determine the optimal dosage or intensity of an intervention or a specific component of an intervention In Juans scenario practice is the component and he is systematically varying the amount of daily practice time eg 30 60 90 minutes to find the most effective dosage for learning new songs This directly aligns with the definition of a parametric analysis In contrast A Component Analysis aims to identify which specific elements or components of a multielement intervention are responsible for behavior change eg is it extinction reinforcement or both It asks which parts are effective not how much of a part is effective A Reversal Design ABAB involves repeatedly introducing and withdrawing an intervention to demonstrate its functional control over behavior An Alternating Treatments Design rapidly alternates between two or more distinct interventions or baseline and intervention to compare their effectiveness Since Juan is investigating varying amounts of practice a parametric analysis is the correct experimental approach
