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 Board Certified Behavior Analyst (BCBA) is planning to use a changing criterion design to increase a client’s independent work duration. Considering the principles of this design, which of the following statements is FALSE regarding the changing criterion design?

The behavior targeted must already be in the client’s repertoire.

The criterion for reinforcement should be systematically changed in a stepwise fashion.

A stable baseline is typically required before implementing the intervention.

To demonstrate a functional relation, the criterion should be occasionally changed back to a previous level.

The changing criterion design is a singlesubject experimental design primarily used to evaluate the effects of an intervention on a behavior that is already in the clients repertoire and can be gradually increased or decreased Unlike some other singlesubject designs eg ABAB reversal designs a stable baseline is not a prerequisite for the changing criterion design The design demonstrates experimental control by showing that changes in the target behavior closely track the changes in the performance criterion To strengthen the demonstration of functional control the criterion may be temporarily returned to a previous level reversal to see if the behavior reverts or changed to a new different level The systematic stepwise changes in the criterion are what allow for the demonstration of experimental control
