This document describes the FAB (Functionally Alert Behavior) Strategies approach to improving behavior in children and adolescents with complex behavioral challenges. FAB Strategies include environmental adaptations, sensory modulation techniques, positive behavioral support, and physical self-regulation strategies. They can be used by teachers, parents, and therapists to improve behavior in students with developmental, sensory processing, and mental health disorders. The strategies are individualized and aim to develop skills like attention, self-control, and functional communication to reduce aggression and interference with learning.
