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. When an applied behavior analyst systematically adds and removes interventions or treatments during a study, what is the primary variable they are attempting to control or influence, and whose changes they are observing?

The independent variables (IVs)

The dependent variables (DVs)

Confounding variables

Extraneous variables

In experimental design interventions or treatments are considered the independent variables IVs because they are systematically manipulated by the experimenter The behavior that is being measured and is expected to change as a direct result of these manipulations is the dependent variable DV The primary goal when adding and removing IVs is to establish experimental or functional control which means demonstrating that the observed changes in the dependent variable are indeed caused by the manipulations of the independent variable rather than by other factors While confounds and extraneous variables are important to identify and control they are threats to experimental control that we aim to minimize the direct target of control and observation through IV manipulation is the DV
