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.

#1. Joe, an RBT, is assigned to collect frequency data on a client’s elopement behavior. On Monday, he meticulously records six instances of the client eloping from the workspace. On Tuesday, however, he records five instances of the client engaging in crying. On Wednesday, he records four instances of the client displaying aggressive behaviors. Considering his supervisor’s original instruction to track elopement, what crucial aspect is most evidently compromised in Joe’s overall data collection efforts?
Joes data collection most clearly lacks validity Validity in measurement refers to the extent to which a measurement procedure actually measures what it is intended or supposed to measure Joe was instructed to measure elopement and while he did so on Monday on subsequent days he shifted to measuring crying and aggression Therefore his data from Tuesday and Wednesday are not valid measures of elopement which was his assigned target behavior Accuracy refers to whether the observed data accurately reflect the true values or actual occurrences of the behavior The question states Joe meticulously records the instances suggesting that for the behaviors he chose to record the counts might be accurate The issue isnt necessarily that his counts are wrong but that hes counting the wrong thing Reliability refers to the extent to which a measurement procedure yields the same value when repeatedly measuring the same event We do not have sufficient information to assess the reliability of Joes measurements as we only have one data point for each type of behavior on different days Consistency is a general term describing uniformity or agreement While Joes data collection is inconsistent hes not consistently measuring elopement validity is the precise and most appropriate technical term from ABAs fundamental dimensions of measurement that describes the failure to measure the intended behavior
