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!

 

Results

#1. Prior to a two-week Christmas break, several students in a classroom setting consistently stopped requesting to play with Legos during their free time, despite Legos being a previously highly preferred item. Upon returning from vacation, all of the students immediately began requesting the Legos for break time once again. Considering this sequence of events, what change in motivating operations (MOs) most likely occurred during the vacation period regarding the Legos?

Satiation

Reinforcement of Lego play

Punishment for Lego play

Deprivation

Before the Christmas break the students likely experienced satiation A with Legos meaning prolonged exposure or access to Legos decreased their reinforcing effectiveness and thus reduced the likelihood of requesting them During the twoweek vacation the students were likely deprived D of Legos meaning their access to Legos was restricted or absent Deprivation is an establishing operation EO that increases the current effectiveness of a stimulus as a reinforcer and increases the frequency of all behavior that has been reinforced by that stimulus When they returned from vacation the value of Legos as a reinforcer had increased due to this period of deprivation leading them to request Legos once again Reinforcement B or punishment C cannot be determined without specific information about the consequences of their behavior during the break the question specifically asks what occurred during vacation to change the motivating operation for Legos
