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. In a behavioral intervention program, a Board Certified Behavior Analyst (BCBA) designs a study to address a client’s challenges with independent task completion. The BCBA introduces various schedules of reinforcement and punishment, carefully observing their impact on the client’s ability to complete tasks without prompts. Which component in this experimental design represents the dependent variable?

The specific schedules of reinforcement and punishment implemented

The BCBA’s systematic manipulation of the intervention

The client’s rate of independent task completion

The observed functional relation between the intervention and task completion

The dependent variable DV in an experimental design is the specific behavior or outcome that is being measured and is expected to change as a result of the intervention It is dependent on the changes made to the independent variable In this scenario the BCBA is manipulating the schedules of reinforcement and punishment these are the independent variables or IVs to see if they can alter the clients rate of independent task completion Therefore the clients rate of independent task completion is the behavior that is being measured and is hypothesized to be affected by the intervention making it the dependent variable Options A and B describe elements of the independent variable which is what is being manipulated Option D the functional relation describes the ultimate goal or finding of the experiment that a change in the IV caused a change in the DV rather than the dependent variable itself
