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 tracking a client’s engagement in manding (requesting) behavior during a 30-minute play session each day. Over five consecutive days, the client’s manding frequency was recorded as follows Day 1 8 mands, Day 2 12 mands, Day 3 10 mands, Day 4 9 mands, Day 5 11 mands. What was the client’s average daily frequency of manding over these five days?

A) 9 mands per day

B) 10 mands per day

C) 10.5 mands per day

D) 11 mands per day

To calculate the average frequency you must first sum all the recorded frequencies and then divide the total by the number of observation periods in this case the number of days 1 Sum the frequencies 8 mands 12 mands 10 mands 9 mands 11 mands 50 mands 2 Count the number of observation periods There are 5 days of data 3 Divide the total frequency by the number of periods 50 mands 5 days 10 mands per day This calculation aligns with the method demonstrated in the text for calculating averages where individual frequency counts are added together to get a total before averaging The most important step is to correctly add the frequencies and then divide by the correct number of data points
