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. Two weeks after an intervention plan has been initiated for a client with severe challenging behaviors, a Board Certified Behavior Analyst (BCBA) conducts a full observation session. During this session, the BCBA requests the Registered Behavior Technician (RBT) to specifically run various intervention procedures as outlined in the client’s behavior plan. While observing, the BCBA meticulously collects data on whether the RBT is correctly following each step of the intervention protocols. What is the BCBA primarily assessing in this scenario?
The scenario describes the BCBA observing the RBT and collecting data on how the intervention is being carried out and whether they are correctly following each step of the intervention protocols This directly refers to the concept of treatment integrity also known as procedural fidelity Treatment integrity is the extent to which an independent variable ie the intervention is implemented as planned Ensuring high treatment integrity is crucial because an interventions effectiveness cannot be accurately evaluated if it is not implemented consistently and correctly Interobserver Agreement IOA Option A involves two or more independent observers collecting data on the clients behavior and comparing their agreement not a supervisor assessing an RBTs implementation accuracy External validity Option B refers to the generalizability of an interventions effects to other settings populations or behaviors which is not the focus of this observation within the learning environment Internal validity Option D refers to the extent to which an intervention is truly responsible for a behavior change establishing a functional relationship while important the BCBA in this specific scenario is focused on how the intervention is being delivered which is a prerequisite for establishing internal validity but not internal validity itself
