BCBA Applications Exam Tips
Strategies for passing the Applied Behavior Analysis, Behavior-Change Procedures section of the BCBA exam.
Always identify the function first
Before selecting an intervention, identify the function of the behavior. The exam frequently presents a scenario and asks you to choose the best intervention. If you do not correctly identify the function (attention, escape, tangible, automatic), you will select the wrong intervention every time.
Know your differential reinforcement procedures
DRA, DRI, DRO, DRL, and DRH are heavily tested. For each, know the definition, how it works, when to use it, and potential limitations. DRA reinforces an alternative behavior. DRI reinforces an incompatible behavior. DRO reinforces the absence of behavior for a time period.
Understand prompting hierarchies and fading
Know both most-to-least and least-to-most prompting strategies, when each is appropriate, and how to systematically fade prompts. The goal is always to achieve independent responding. Failing to fade prompts is a common clinical mistake tested on the exam.
Study extinction procedures and side effects
Know that extinction must match the function of the behavior. Extinction for attention-maintained behavior looks different from extinction for escape-maintained behavior. Also study extinction bursts, spontaneous recovery, and emotional side effects of extinction.
Focus on generalization and maintenance programming
The exam frequently asks how to program for generalization and maintenance. Know strategies: train sufficient exemplars, use natural reinforcers, program common stimuli, train loosely, and use intermittent reinforcement. These topics appear across multiple question types.
