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.

Results

#1. Following a successful functional analysis, a BCBA determined that differential reinforcement of other behavior (DRO) is an effective intervention for reducing a client’s repetitive vocalizations. Now, the BCBA wants to fine-tune the intervention. Specifically, they are interested in finding the most efficient and effective interval for the DRO schedule (e.g., DRO 30 seconds, DRO 60 seconds, DRO 120 seconds) that yields the greatest reduction in vocalizations while still being practical to implement. What type of analysis is the BCBA planning to conduct to answer this question?

Comparative analysis

Component analysis

Parametric analysis

Multiple baseline design

The text explains parametric analysis as now when you get the parametric analysis youve identified your component and now youre going to ask yourself how much do I need its basically the dosage if youve identified the medicine that works for you then you need to identify how much medicine do you need In this scenario the BCBA has already identified DRO as an effective intervention the medicine that works The question is now about optimizing the dosage or specific parameter of that intervention in this case the interval for the DRO schedule This directly aligns with the definition and purpose of a parametric analysis Comparative analysis A is for comparing entirely separate interventions Component analysis B is for breaking down a multicomponent treatment package A multiple baseline design D is an experimental design not a type of analysis focused on dosage
