A functional Behavior Assessment (FBA) is an approach school teams use in order to figure out what may be causing a student to act in a certain way. It's purpose is to allow school teams to understand what may be causing a certain behavior so they can find ways to change the behavior by developing a plan to implement. Often an FBA is used as part of the school evaluation for special education if a student's behavior is impacting their learning. It can also be used if a student already has a 504 plan or an IEP but new behaviors are arising impacting the student academic learning. Another situation that a FBA would be used is if a student has a major discipline or has to be removed from school due to their behavior.
