AUTISM GLOSSARY
Functional Behavioral Assessment (FBA)
DEFINITION
An FBA is a systematic process for identifying the function — the 'why' — of a specific behavior. Understanding what need a behavior meets allows for the development of supports that address that need more effectively.
WHY IT MATTERS
Addressing the function of a behavior (communication, sensory regulation, escape, attention) leads to lasting change. Punishing behavior without understanding its function is likely to fail or displace the behavior to something else.
COMMON MISCONCEPTION
An FBA is not about proving a child is misbehaving. It is about understanding what need they are meeting and finding better ways to meet it. It should lead to support, not punishment.
