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. Timothy developed a conditioned reflex where a car alarm (conditioned stimulus) now reliably elicits sneezing (conditioned reflex), previously only associated with black pepper (unconditioned stimulus). As a Board Certified Behavior Analyst (BCBA), how would you systematically implement respondent extinction to eliminate Timothy’s sneezing in response to the car alarm?

A) Identify the automatic function of sneezing and withhold all sensory stimulation reinforcement.

B) Withhold the car alarm while presenting the black pepper until sneezing no longer occurs.

C) Repeatedly present the car alarm without the presence of black pepper until sneezing no longer occurs.

D) Present the black pepper and the car alarm simultaneously until the sneezing habituates.

Respondent extinction is a procedure used to eliminate a conditioned reflex CR by repeatedly presenting the conditioned stimulus CS in the absence of the unconditioned stimulus US In this scenario the car alarm is the CS and the black pepper is the US Timothys sneezing is the CR Therefore to extinguish the sneezing in response to the car alarm the car alarm must be presented over and over again without the presence of black pepper until sneezing no longer occurs Options A and D incorrectly apply operant conditioning concepts like functions and reinforcement or describe an incorrect procedure for extinction Option B describes the opposite process attempting to remove the CS while presenting the US which would not lead to respondent extinction
