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.

Results

#1. A team of behavior technicians is tasked with tracking instances of a client’s aggressive behavior. After reviewing video recordings, two technicians independently record the number of aggressive incidents. Technician A records 15 incidents, while Technician B records 5 incidents during the same observation period. The supervisor notes that there is a significant discrepancy in their recordings, indicating a lack of agreement. The text provided discusses a similar scenario where students are not agreeing on who started a fight. Based on the information provided and the discussion in the text, what specific measurement quality is demonstrably lacking in the scenario with the behavior technicians?

Accuracy

Reliability

Validity

Inter-observer agreement

The scenario directly describes a situation where two independent observers technicians record different counts of the same behavior which is a clear indication of a lack of interobserver agreement IOA IOA is the degree to which two or more independent observers report the same observed values after measuring the same events The provided text explicitly states the only thing we know for certain it lacks is agreement okay these students are not agreeing theres no interobserver agreement on who actually started the fight While a lack of agreement can impact accuracy how well the measurement reflects the true value and reliability the consistency of measurement over time or across observers the direct observable deficit in this scenario as highlighted by the text is the agreement between observers Validity refers to measuring what is intended to be measured Without sufficient IOA it becomes difficult to confidently assess other aspects of measurement quality
