PBIS - A Three-Tiered Model:
PBIS schools organize their evidence-based behavioral practices and systems into an integrated collection or continuum in which students experience supports based on their behavioral responsiveness to intervention. A three-tiered prevention logic requires that all students receive supports at the universal or primary tier. If the behavior of some students is not responsive, more intensive behavioral supports are provided, in the form of a group contingency (selected or secondary tier) or a highly individualized plan (intensive or tertiary tier).
