**In short:** A systematic process to understand why a student engages in challenging behavior by identifying triggers and maintaining factors.
A **Functional Behavior Assessment (FBA)** is a systematic process used to understand why a student engages in challenging behavior. The FBA identifies environmental factors that trigger and maintain behaviors, helping teams develop effective intervention strategies.

## FBA Process

FBAs typically include record review, interviews with teachers and parents, direct observation, and data analysis. The assessment identifies antecedents (triggers), behaviors of concern, and consequences that may reinforce behaviors. Results inform development of a Behavior Intervention Plan.

## When FBAs Are Required

IDEA requires FBAs when a student with a disability faces disciplinary removal that constitutes a change of placement, if behavior is related to the disability. FBAs are also best practice for any student with persistent behavioral challenges.

## Frequently asked questions

FBAs should be conducted by professionals trained in behavior analysis, often school psychologists or behavior specialists, with input from teachers and parents.
