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 technician reports that a client, who typically enjoys playing with building blocks, refused to engage with them during their afternoon session. The technician noted that earlier in the day, the client had an exceptionally long free play session where they spent over three hours exclusively playing with the same set of building blocks. Based on this information, the extensive prior exposure to the building blocks likely functioned as what type of motivating operation in relation to the client’s current interest in the blocks?
This scenario describes the phenomenon of satiation which is a type of abolishing operation AO A Motivating Operation MO has two primary effects a valuealtering effect and a behavioraltering effect In this case the extensive prior exposure playing for three hours to the building blocks acted as an AO The valuealtering effect of this AO was to decrease the reinforcing effectiveness of playing with blocks making the blocks less desirable The behavioraltering effect specifically an abative effect was to decrease the current frequency of behaviors that had previously been reinforced by playing with blocks ie the client refused to engage with them An establishing operation EO would increase the effectiveness of the blocks as a reinforcer and increase the frequency of behaviors to obtain them A discriminative stimulus SD signals the availability of a reinforcer for a specific behavior not a change in the reinforcers value or the desire for it A reinforcing consequence is something that immediately follows a behavior and increases the future probability of that behavior which is the opposite of what is described here
