A functional behavior assessment is used to study a behavior and figure out what is causing the behavior to occur. The behavior must first be defined, as specifically and objectively as possible. Then data is gathered and analyzed to determine if their are trends, and focused on the antecedents and consequences. Ultimately the FBA is used to determine the driving force/purpose behind the behavior. Situations where an FBA can be used are when students are engaging in disruptive or withdrawn behavior.
