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. Sam orders lobster (Stimulus A) at a restaurant and states, ‘This is delicious’ (Stimulus B). The next evening, Sam’s son orders steak (Stimulus C) and similarly states, ‘This is delicious’ (Stimulus B). Later that week, someone asks Sam if he has had anything ‘delicious’ (Stimulus B) recently, and Sam promptly replies, ‘I ate steak’ (Stimulus C) the other night. According to the principles of stimulus equivalence, what specific type of derived, untrained stimulus-stimulus relation is demonstrated by Sam’s final statement, ‘I ate steak,’ in response to the question about ‘delicious’ food?
To analyze this lets map out the given and derived relations 1 Trained Relation 1 Sam orders lobster A and calls it delicious B So A B Lobster is Delicious 2 Trained Relation 2 Sams son orders steak C and calls it delicious B So C B Steak is Delicious The question specifically asks about the last statement When asked about delicious B Sam replies I ate steak C This demonstrates the relation B C Delicious is Steak Lets review the types of stimulus equivalence relations Reflexivity AA The stimulus is matched to itself eg Lobster Lobster This is not demonstrated here Symmetry If AB then BA If a stimulus is equivalent to another the reverse is also true In our scenario we have the trained relation C B Steak is Delicious Sams derived response B C Delicious is Steak perfectly illustrates symmetry The listener presented the stimulus B delicious and Sam responded with C steak Transitivity If AB and BC then AC This is a derived relation where if A is related to B and B is related to C then A is also related to C While A lobster and C steak are both related to B delicious the final statement BC is a direct reversal of CB making it an example of symmetry rather than the full AC transitive relation Generalization while related to stimulus control is not one of the defined stimulus equivalence relations
