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 BCBA is explaining basic behavioral principles to a new Registered Behavior Technician (RBT). They use an analogy ‘Each night, you like to enjoy a cup of tea before bed. You grab your electric kettle, add water, and set it to boil. After a few minutes, the water is ready, and the kettle beeps. Upon hearing the beep, you immediately pour the hot water over your tea leaves.’ In this scenario, what does the kettle’s beep primarily represent?

A motivating operation (MO) for pouring water

A consequence for grabbing the kettle

A discriminative stimulus (SD) for pouring water

An antecedent for drinking the tea

A discriminative stimulus SD is an antecedent stimulus that signals that a particular response if emitted will be reinforced In this example the kettles beep signals that the water is ready and therefore the response of pouring the water over the tea leaves will lead to the desired outcome making tea The motivation to drink tea the value of the reinforcer is established by a motivating operation MO which increases the effectiveness of the reinforcer and evokes behavior that has been reinforced by that reinforcer in the past However the beep itself does not increase the value of the tea or evoke the desire for tea it simply indicates that the necessary condition for obtaining the tea hot water is met and the response pouring will now be effective The beep is not a consequence for grabbing the kettle as grabbing the kettle occurred earlier While the beep is an antecedent to pouring the water pouring the water itself is the more direct antecedent to drinking the tea
