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!

#1. A BCBA is reviewing a scatter plot of a client’s biting behavior, which records occurrences from 8 AM to 3 PM daily. The goal is to identify patterns and then conduct focused observations for antecedents and consequences. Based on the principle of effective observation using scatter plots, if the scatter plot shows very few or no instances of biting between 2 PM and 3 PM, while other periods (e.g., 8 AM – 10 AM, 11 AM – 1 PM) show frequent occurrences, which time period would be the LEAST effective for observing potential antecedents and consequences for biting?

8 AM – 10 AM

11 AM – 1 PM

2 PM – 3 PM

Any time period would be equally effective for observation

A scatter plot is a data display method that helps identify temporal patterns of behavior by showing the distribution of occurrences across specific time periods The primary purpose of observing antecedents and consequences is to gather information about the environmental events that reliably precede antecedents or follow consequences the target behavior which is crucial for conducting a functional assessment If the behavior rarely or never occurs during a specific time period as indicated by very few or no data points on the scatter plot for 2 PM 3 PM in this scenario there will be little to no opportunity to observe its antecedents and consequences Therefore this period would be the least effective for gathering relevant data for a functional assessment Conversely periods with higher rates of the target behavior eg 8 AM 10 AM 11 AM 1 PM would provide more frequent opportunities for observation and thus more data points to analyze the ABC contingencies
