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. A newly certified BCBA is overseeing an RBT who is collecting skill acquisition data for a client. The BCBA wants to ensure the RBT’s data collection is accurate and reliable. The BCBA has been conducting interobserver agreement (IOA) checks for 10 of the RBT’s sessions. According to best practice and the ‘gold standard’ in Applied Behavior Analysis, what is the recommended frequency for conducting IOA checks, and why is this level of frequency important?

10 of sessions because it is sufficient to catch major errors and maintain a reasonable schedule.

25-33 of sessions to ensure the data is accurate, reliable, and valid, and that measurement is consistent across observers.

50 of sessions to guarantee complete agreement between observers and prevent any data discrepancies.

Whenever a new RBT starts to establish baseline accuracy, and then the frequency can be significantly reduced or eliminated.

The provided text explicitly states that the gold standard for Interobserver Agreement IOA is to take it during 25 to 33 percent of sessions It emphasizes that this frequency is crucial to really determine okay am I taking the right data is my measurement correct are we measuring the same thing is my data accurate is it reliable is it valid The text further clarifies that taking IOA for only 10 of sessions its just not going to be useful enough as error alone could make that invalid highlighting the necessity of the higher frequency for robust data quality and ensuring the integrity of the collected information
