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. During a training session, three RBT trainees are instructed to record the number of times a client engages in ‘off-task behavior,’ defined as disengaging from the assigned worksheet for more than 10 consecutive seconds. After observing the same video recording of the client, Trainee 1 reports 4 instances, Trainee 2 reports 3 instances, and Trainee 3 reports 2 instances. Given this information, what specific aspect of their measurement is most clearly lacking?

Accuracy

Validity

Inter-observer agreement (IOA)

Reliability

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 three different trainees observed the exact same behavior but reported three different counts 4 3 and 2 This discrepancy directly indicates a lack of IOA as their measurements do not match While a lack of IOA can sometimes suggest issues with accuracy measuring what actually occurred or reliability consistency over repeated measurements the immediate and most direct observation from the provided data is the disagreement between observers Validity measuring what you intended to measure seems to be in place as they are all attempting to measure offtask behavior as defined
