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. Susan is attempting to refine a recipe by identifying a specific seasoning she dislikes. She remakes the dish multiple times, each time removing one seasoning to determine which one is affecting the taste negatively. This systematic process of removing individual components of an intervention to identify which part is responsible for the overall effect is best described as which of the following analytical methods?

Component analysis

Parametric analysis

Multiple probe design

Withdrawal design

The text explicitly defines a component analysis as removing parts of the intervention to see which one is affecting it which one is working which one is not Susans method of removing one seasoning at a time from her recipe precisely matches this definition as she is isolating the specific component seasoning that is causing the disliked taste In contrast parametric analysis involves varying the amount or dosage of an intervention component not its presence or absence Multiple probe and withdrawal designs are types of singlesubject experimental designs used to evaluate the effectiveness of interventions not to isolate individual components within an intervention like a component analysis does
