Functional Behavioral Assessment (FBA) and Behavior Intervention Plan (BIP): a parent guide

An FBA is generally used to understand the function or purpose of behavior so the team can design effective positive supports; a BIP uses that information to plan strategies and supports.

IDEA and Section 504 are federal laws, but states and school districts can have additional procedures, forms, timelines and protections. Check your state education agency and district notices.

Behavior is a required IEP consideration

When a child’s behavior impedes the child’s learning or that of others, IDEA requires the IEP Team to consider positive behavioral interventions and supports and other strategies. Supports may be reflected through goals, services, supplementary aids, program modifications or supports for school personnel.

What is an FBA?

Federal guidance describes an FBA as a process for identifying the reasons behind, or factors contributing to, behavior. IDEA does not prescribe one standard set of FBA components for every situation, so state rules and professional practice may add detail.

What is a BIP?

A behavior intervention plan is commonly developed from functional information to prevent or reduce behavior that interferes with learning and to teach or reinforce more effective skills and supports. The plan should be individualized and connected to the student’s needs.

FBA and BIP in the discipline context

If conduct is determined to be a manifestation of the child’s disability, IDEA requires the IEP Team to conduct an FBA and implement a BIP unless an FBA had already been conducted before the behavior, or to review and modify an existing BIP as necessary.

Useful questions for parents

Ask what behavior is being defined, what data are being collected, what patterns or triggers are being considered, what replacement skills will be taught, what adult supports are needed, and how the team will know whether the plan is working.
