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.

If you want to keep practicing, check out the BCBA section for more tests and study materials!

 

Results

#1. A BCBA is reviewing a student’s data on a graph for the frequency of out-of-seat behavior across four consecutive school days. The data points plotted for Day 1, Day 2, Day 3, and Day 4 consistently show a clear and substantial downward slope. Based on this visual analysis, how would the trend of the data be most accurately described?

An increasing trend

A decreasing trend

A stable trend

A variable trend

Visual analysis of graphed data is a fundamental skill in Applied Behavior Analysis for interpreting intervention effectiveness When data points on a graph consistently show a clear and substantial downward slope from one measurement point to the next eg from Day 1 to Day 4 it indicates a decreasing trend This means the rate frequency or magnitude of the behavior is generally reducing over time An increasing trend would show an upward slope indicating the behavior is increasing A stable trend would show data points clustering around a relatively consistent level with minimal variability A variable trend would show significant fluctuations and a lack of a clear consistent direction neither consistently increasing nor decreasing
