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 Board Certified Behavior Analyst (BCBA) is overseeing an intervention designed to decrease a client’s elopement behavior during community outings. The intervention has been in place for a few days, and while the frequency of elopement has slightly decreased, the behavior continues to occur at socially unacceptable rates, posing safety concerns. After reviewing the collected data, the BCBA notes no clear downward trend, and the intervention’s effectiveness appears questionable. According to best practice in Applied Behavior Analysis, when should the BCBA consider discontinuing or significantly modifying this intervention?

After a minimum of two weeks of implementation to ensure sufficient data collection and allow the intervention to ‘settle in’.

Once at least three consecutive therapy sessions have been completed, irrespective of the varied duration or intensity of those sessions.

As soon as the systematically collected data reliably indicates that the intervention is not producing the desired, socially significant outcomes.

Only as a last resort, after all possible minor adjustments to the current intervention have been exhausted, to avoid frequent changes.

In Applied Behavior Analysis intervention decisions are strictly datadriven and focused on achieving socially significant outcomes efficiently The text emphasizes that there is no fixed timeline like two weeks or session count like three sessions for evaluating an interventions effectiveness as session length and context can vary greatly making such rules arbitrary and imprecise The core principle is to discontinue or adjust an intervention as soon as the data demonstrates it is unsuccessful Holding onto an ineffective intervention out of a reluctance to change or a belief that it will eventually work ie marrying interventions is counterproductive and unethical as it delays effective treatment for the client The goal is to move quickly and adjust interventions as needed to find the most effective path toward meaningful outcomes
