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 behavior analyst is conducting a research study to evaluate the effectiveness of a new social skills intervention for adolescents with autism spectrum disorder. The analyst plans to systematically introduce, withdraw, and then reintroduce components of the intervention across different phases of the study to observe their impact on the participants’ social interaction behaviors. When the behavior analyst is engaging in the systematic process of adding, removing, or modifying these intervention components within the experimental design, what specific type of variable is the analyst manipulating to determine its effect on the target behavior?

A. Dependent Variables

B. Confounding Variables

C. Independent Variables

D. Extraneous Variables

In experimental design within Applied Behavior Analysis the independent variable IV is the environmental event or condition that the researcher systematically manipulates introduces or withdraws to determine its effect on the behavior of interest In this scenario the intervention components eg specific social skills teaching strategies prompts reinforcement contingencies are precisely what the behavior analyst is manipulating adding removing modifying The purpose of these manipulations is to observe whether changes in these interventions cause changes in the target behavior The dependent variable DV is the behavior being measured eg social interaction behaviors Confounding variables are uncontrolled factors that might inadvertently influence the dependent variable potentially obscuring the true effect of the IV Extraneous variables are all other environmental variables not directly controlled or measured in the experiment
