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 BCBA is planning to implement an intervention to address a challenging behavior exhibited by a client. To demonstrate experimental control and evaluate the intervention’s effectiveness across various contexts, the BCBA decides to use a multiple baseline design. This design strategy is typically conducted across three or more specific elements simultaneously to show that the intervention is responsible for behavior change. Which of the following is NOT an element across which a multiple baseline design is typically implemented?
A multiple baseline design is a powerful singlesubject experimental design used to demonstrate experimental control by introducing an intervention at different times across multiple baselines The core idea is that the behavior should only change when the intervention is introduced to that specific baseline while behavior in other baselines remains unchanged These baselines can be established across 1 Behaviors Implementing the intervention sequentially for different but similar behaviors of the same individual 2 Participants Implementing the intervention sequentially for the same behavior across different individuals 3 Settings Implementing the intervention sequentially for the same behavior of the same individual across different environments or settings A multiple baseline design is NOT used to compare different treatments simultaneously Comparing different treatments is typically done using alternating treatments designs or multielement designs where different interventions are rapidly alternated within the same phase to assess their relative effectiveness
