What is a Functional Behavioral Assessment (FBA) and how does it inform Behavioral Intervention Plans (BIP)?

• A. FBA identifies antecedents, behaviors, and consequences to determine the function of behavior; it informs BIP by specifying evidence-based strategies and replacement behaviors to reduce challenging behaviors.
• B. FBA measures IQ scores; it informs BIP by ranking behaviors by severity.
• C. FBA is a parent survey about behavior; it informs BIP by setting punishment strategies.
• D. FBA is an academic achievement test; it informs BIP by identifying reading deficits.

Answer: (A)

The main idea is that a Functional Behavioral Assessment uses a structured analysis of what happens before, during, and after a behavior (the antecedents and consequences) to determine the function or purpose the behavior serves for the student. This functional picture then guides a Behavioral Intervention Plan by choosing evidence-based strategies and a replacement behavior that achieve the same function but with less disruption, along with prevention and reinforcement components to support the new behavior.

In practice, you collect data (through direct observation, ABC charts, or interviews) to form a functional hypothesis about why the behavior happens—common functions include seeking attention, escaping a task, obtaining a tangible item, or meeting a sensory need. With that function in mind, the BIP specifies concrete strategies: modify the environment to prevent triggers, teach and reinforce an appropriate replacement behavior that serves the same function, and use consistent consequences to reduce the challenging behavior while gradually fading supports as the student improves.

The other options don’t fit because an FBA is not about measuring IQ or ranking behaviors by severity, not a parent survey focused on punishment, and not an academic achievement test identifying reading deficits.
