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 Board Certified Behavior Analyst (BCBA) has determined that a differential reinforcement of alternative behavior (DRA) procedure is effective in reducing a child’s disruptive classroom behaviors. The BCBA now wants to optimize the DRA by determining the most effective schedule of reinforcement for the alternative behavior (e.g., reinforcing every 1 minute, every 3 minutes, or every 5 minutes). Which type of experimental analysis would be most appropriate for the BCBA to conduct to determine the optimal schedule or ‘dosage’ of reinforcement?

Comparative analysis

Component analysis

Parametric analysis

Task analysis

A parametric analysis is an experimental design used to evaluate the effects of varying the amount intensity or value of a single independent variable on behavior In this case the independent variable is the schedule of reinforcement within the DRA procedure The BCBA is not comparing entirely different interventions comparative analysis nor are they breaking down an intervention package into its individual parts component analysis They are also not identifying the steps in a complex skill task analysis Instead they are systematically manipulating a specific parameter the interval of the reinforcement schedule of an already chosen intervention to find the most effective dosage which is the hallmark of a parametric analysis
