BCBA Applications Common Mistakes
What trips up most candidates on the Applied Behavior Analysis, Behavior-Change Procedures section.
Selecting an intervention before identifying the function
The most common error in ABA practice and on the exam. If you choose a DRA procedure for escape-maintained behavior but reinforce an alternative that does not serve the escape function, the intervention will fail. Always conduct an FBA or functional analysis first.
Confusing DRA, DRI, DRO, and DRL
DRA reinforces any appropriate alternative behavior. DRI reinforces a behavior physically incompatible with the problem behavior. DRO reinforces the absence of the problem behavior for a specified time. DRL reinforces lower rates of the behavior. Know each definition and when to apply each.
Failing to plan for prompt fading
Using prompts without a fading plan creates prompt dependency. Always have a systematic plan for reducing prompts (e.g., most-to-least fading, time delay). The exam tests whether you know how to move from prompted to independent responding.
Ignoring extinction side effects
Extinction can produce extinction bursts, emotional responses, aggression, and spontaneous recovery. Failing to prepare for these side effects or failing to warn caregivers can undermine an intervention. The exam tests whether you understand these potential outcomes.
Not programming for generalization
A skill taught in one setting with one person using one set of materials may not generalize. Use multiple exemplars, vary training conditions, use natural reinforcers, and train in the natural environment whenever possible.
