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.

#1. During a differential reinforcement of alternative behavior (DRA) procedure, a BCBA is training a replacement behavior to compete with an interfering behavior. The intervention plan dictates that the replacement behavior will receive reinforcement. Assuming the DRA procedure is implemented perfectly and the chosen reinforcer is effective, what factor is generally considered most crucial for the long-term success of the intervention regarding the reinforcement for the replacement behavior?
While the magnitude of a reinforcer can play a role the text emphasizes that consistent delivery and control of reinforcement is more important For a differential reinforcement procedure like DRA to be effective it is paramount that the replacement behavior is reliably and consistently reinforced whenever it occurs and that access to the reinforcer is controlled This prevents bootleg reinforcement where the individual obtains the reinforcer through means outside of the planned intervention which can undermine the procedure Consistency ensures that the contingency between the replacement behavior and reinforcement is strong and predictable making the replacement behavior more likely to occur in the future Novelty is not a primary consistently crucial factor an effective reinforcer might be the same one used repeatedly if it continues to maintain its reinforcing properties Immediate availability in all relevant settings not just where interfering behavior occurred and generalization across settings are also important but the core issue of consistent controlled delivery is highlighted as paramount for the effectiveness of the reinforcer itself within the intervention
