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. A client is looking for their wireless headphones. They typically keep them in a specific drawer in their desk. When the client opens the drawer, they discover the headphones are not there. Assuming the client’s behavior of opening the drawer is part of a chain to obtain the headphones (a reinforcer), what environmental role does the open, empty drawer now play in relation to finding the headphones?

An SD (Discriminative Stimulus) for the availability of the headphones.

An S-Delta (S) for the unavailability of the headphones.

An SD for negative reinforcement, signaling the removal of a search-related aversive stimulus.

An S-Delta (S) for punishment, signaling that punishment is not available.

An SDelta S is a stimulus that signals that a particular behavior will NOT be reinforced in its presence In this scenario the clients behavior of opening the drawer is typically reinforced by finding the headphones However upon opening the drawer and finding it empty the drawer as a stimulus now signals that the reinforcement the headphones is not available Therefore the open empty drawer functions as an SDelta for the reinforcement of finding the headphones An SD in contrast would signal the availability of reinforcement The situation does not primarily describe negative reinforcement or punishment availability but rather the absence of a desired positive reinforcer
