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 behavior analyst is observing a client who frequently searches for a specific comfort item (a weighted blanket) in various locations around their home. On one occasion, the client checks their bedroom closet, which they have previously found the blanket in, but the blanket is not there. The client then moves on to search another room. Based on this specific instance, regarding the availability of the weighted blanket as positive reinforcement, what stimulus function does the bedroom closet most accurately serve in this moment?

An SD for positive reinforcement

An S-Delta for positive reinforcement

An SD for negative reinforcement

An S-Delta for punishment

The provided text defines an SDelta S as a stimulus that signals that reinforcement is not available for a particular response In this scenario the client searches the closet a response for the weighted blanket positive reinforcement When the blanket is not found the closet ceases to signal the availability of that reinforcement and instead signals its unavailability Therefore the closet functions as an SDelta for positive reinforcement It is not an SD for positive reinforcement because the reinforcement blanket was not present It is not an SD for negative reinforcement as its not signaling the availability of the removal of an aversive stimulus There is insufficient information to determine if its an SDelta for punishment as punishments availability or unavailability is not the primary focus of the clients search behavior in this context
