Dana Do’s: How to Navigate Performance-Based BCBA® Exam Questions

Dana Do's: How to Navigate Staff Performance-Based BCBA® Exam Questions

TCO domain item I.6 asks us to use a function-based approach such as performance diagnostics to assess and improve supervise behavior. This is a clue about how to navigate performance-based exam questions.

When a question is related to staff performance problems, most people look for solutions rather than thinking about the function. So what does that mean for you on exam day? Well, don’t choose the intervention before you know the variable responsible for the performance problem.

Let’s explore an example. An RBT is not implementing a procedure correctly and the question asks, “What should the supervisor do first?” There may be answer choices like “provide more training,” “give feedback, increase reinforcement,” or “conduct a performance diagnostic.”

Before you start looking for the solution, it is important that you ask yourself whether the scenario tells you why there is a performance problem? Maybe the RBT can’t do it. They were not properly trained or they do not understand the procedure. That would point toward a skill deficit, and so more training may be an appropriate solution. But maybe they can do it, but they just are not. They have demonstrated the skill before, but now the materials are not available. The procedure takes too much effort, expectations are not clear, or there is little reinforcement for doing it correctly. In this case, may be looking at a performance deficit and so more training is not necessarily going to fix that.

So on exam questions, if there is evidence that the supervisee lacks the skill, then that is a good sign it may be correct to choose a training strategy. But, if the cause is unknown, then look for the option that points to assessing the variables that are affecting performance.

The takeaway for Domain I.6 questions: If they cannot do it, think: skill deficit. If they can do it, but are not, think: performance deficit. If you don’t know which one, then assess.
