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 behavior analyst is designing an intervention to reduce a client’s reliance on continuous reinforcement (CRF) and move towards an intermittent schedule to promote stronger, more durable behavior. The analyst understands the importance of avoiding ratio strain. Which of the following strategies is most appropriate to prevent ratio strain when thinning a reinforcement schedule?

Implement large, abrupt increases in the response requirement for reinforcement.

Maintain continuous reinforcement for an extended period to ensure maximum behavior strength before fading.

Significantly reduce the frequency of reinforcement in a single step to quickly transition to an intermittent schedule.

Systematically and gradually fade the reinforcement schedule based on the individual client’s performance and needs.

Ratio strain occurs when the response requirement for reinforcement is increased too rapidly or too abruptly leading to a decrease in responding cessation of behavior or even aggression and avoidance To prevent ratio strain reinforcement schedules should be thinned systematically and gradually This involves making small incremental increases in the response requirement eg moving from FR1 to FR2 then FR3 etc while carefully monitoring the clients behavior The pace of thinning should always be individualized and based on the clients current performance ensuring that the client continues to emit the target behavior at an acceptable rate Making large abrupt increases significantly reducing reinforcement in a single step or maintaining CRF for too long which makes it much harder to fade are all strategies that are likely to induce ratio strain rather than prevent it
