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 Board Certified Behavior Analyst (BCBA) conducted a functional analysis (FA) for a client’s severe self-injurious behavior (SIB). Data from the FA showed that SIB occurred at very low rates in the ‘Control’ (free play) and ‘Escape’ conditions. However, a significant increase in SIB frequency was observed consistently during the ‘Contingent Attention’ condition. Based on these functional analysis results, what is the most likely function of the client’s self-injurious behavior?
In a functional analysis the function of a behavior is identified by observing in which experimental condition the behavior occurs at a significantly higher rate compared to other conditions especially the control condition The scenario explicitly states that SIB barely happened in control and escape conditions but a significant increase in SIB frequency was observed consistently during the Contingent Attention condition This indicates a clear functional relationship between the delivery of attention following SIB and the subsequent increase in SIB Therefore the behavior is most likely maintained by attentionseeking Escape from demand would be indicated by high rates of SIB in the escape condition Automatic reinforcement would typically show high rates across all conditions or specifically in an aloneunstructured condition and is not directly tied to social contingencies like attention or escape Access to tangible items is typically evaluated in a tangible condition which was not identified as the maintaining condition for SIB in this text
