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 has implemented a new behavior-change intervention for a client. After several weeks, a review of the collected data shows no significant progress in the target behavior, and in some areas, the behavior appears to be worsening. The BCBA is evaluating whether to continue or discontinue the intervention. According to behavior-analytic principles regarding intervention fluidity and client outcomes, what is the most appropriate time to discontinue an intervention?

After at least two weeks of collecting data, as this provides a standard minimum period for evaluation.

Once at least three full sessions of data have been collected, to ensure a minimum sample size regardless of session length.

Whenever the collected data clearly and sufficiently indicates that the intervention is unsuccessful in achieving the desired, socially valid outcomes.

Only as a last resort, as discontinuing interventions too frequently can disrupt client routine and reduce the consistency of treatment.

The text highlights that in ABA your treatments are fluid theyre organic we dont get married to a treatment The primary concern is optimal outcomes for our client Therefore the most appropriate time to discontinue an intervention is whenever theres enough data to indicate that the intervention is unsuccessful The text explicitly rejects arbitrary fixed timelines like at least two weeks or at least three sessions because session lengths and consistency can vary significantly making such rules imprecise and potentially ineffective Furthermore it firmly states you should try to avoid discontinuing interventions whenever possible absolutely not emphasizing that behavior analysts should move quickly and be prepared to adjust intervention after intervention until one that works is found aligning with the goal of socially valid and meaningful outcomes
