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. During a playground observation, a teacher asks two students to describe who started a fight. One student reports, The first boy punched the other, while the second student states, The second boy initiated the conflict. Given these conflicting accounts, which characteristic of good data is most certainly lacking in this observation?
Interobserver Agreement IOA refers to the degree to which two or more independent observers report the same observed values after measuring the same events In this scenario two different students observed the same event the start of the fight but provided conflicting reports indicating that they did not agree on what occurred Therefore the observation most certainly lacks Interobserver Agreement While the observation might also lack accuracy we dont know the true start of the fight or reliability we dont know if these students would consistently report the same information if they observed similar events again we cannot state these are certainly lacking based solely on the provided information Validity on the other hand refers to the extent to which data collection measures what it purports to measure In this case the students were asked to observe who started the fight making their observation valid in its intent even if their reports conflict or are inaccurate
