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. Lisa’s parents want her to ride in her car seat without screaming. They begin by praising her when she walks outside without screaming, then when she opens the car door without screaming, and finally for unbuckling the car seat without screaming. The ultimate goal is for Lisa to ride in the car seat calmly. Which behavior-change procedure are Lisa’s parents most likely implementing?
Shaping is a behaviorchange procedure used to teach new behaviors by differentially reinforcing successive approximations to a terminal behavior The parents in this scenario are systematically reinforcing behaviors that progressively get Lisa closer to the desired outcome of riding in her car seat calmly eg walking outside calmly opening the car door calmly unbuckling the car seat calmly Each step is an approximation to the terminal behavior of riding in the car seat without screaming Task analysis while also used for complex behaviors involves breaking down a behavior into a sequence of smaller discrete steps each of which is taught and performed in a specific order to complete the entire chain Here the focus is on gradually modifying a single response class not a chain of distinct steps to perform the car seat activity as a whole like getting in buckling staying put The text specifically notes that they are not conducting the task analysis but rather reinforcing approximations Furthermore the parents are using praise which is a form of positive reinforcement adding a desirable stimulus to increase future behavior not negative reinforcement removing an aversive stimulus or positive punishment adding an aversive stimulus
