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. Dr. Ramirez is conducting an experiment to evaluate the effectiveness of a new teaching procedure on a client’s acquisition of novel vocabulary words. Each day, after implementing the procedure, Dr. Ramirez records the total number of new words the client correctly identifies. She adds this cumulative total to a graph, resulting in a data path that consistently increases over time, never decreasing or remaining flat unless no new words are learned. What type of data display is Dr. Ramirez most likely using?
The text directly addresses this Bob records how many times the mouse gets through the Maze and added that number to a data path that is continually increasing what is Bob using his cumulative record has Skinner recorded his data it was a data path that continually increased went up up up up up endlessly why does that happen because were accumulative recording our data think about typical line graphs that we see right the data paths can go up they can go down they can go all over the place they can be variable cumulative records They just continually go up and up and up forever so if we have a data path that is continually increasing well the cumulative is just a cumulative record A cumulative record is a type of graph on which the cumulative number of responses emitted is represented on the vertical axis The steeper the slope of the data path the greater the response rate The defining characteristic is that the data path never decreases it can only increase or stay flat reflecting the total accumulated responses over time This contrasts with a standard line graph where data paths can fluctuate up and down Scatterplots are used to show the relationship between two variables Bar graphs are typically used for discrete data categories or comparing different conditions rather than tracking continuous changes over time in an accumulative manner
