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. Two researchers are independently collecting frequency data on a client’s manding behavior during four consecutive observation intervals. Their recorded frequencies for each interval are as follows Researcher 1 Interval 1 3, Interval 2 4, Interval 3 3, Interval 4 2 Researcher 2 Interval 1 3, Interval 2 3, Interval 3 4, Interval 4 2 Using the exact count per interval Interobserver Agreement (IOA) method, what is the calculated IOA for this dataset?

100

Exact count per interval IOA is calculated by determining the number of intervals in which both observers recorded the exact same frequency dividing that by the total number of intervals and then multiplying by 100 Lets compare interval by interval Interval 1 Researcher 1 3 Researcher 2 3 Agreement Interval 2 Researcher 1 4 Researcher 2 3 No Agreement Interval 3 Researcher 1 3 Researcher 2 4 No Agreement Interval 4 Researcher 1 2 Researcher 2 2 Agreement There are 2 intervals with exact agreement out of a total of 4 intervals IOA Number of agreements Total number of intervals 100 IOA 2 4 100 050 100 50 The texts example precisely illustrates this calculation first interval three three is their ioa yes were one for one second interval four three is their ioa no so one for two three four ioa no three two two ioa yes two for four divide two by four you get fifty percent
