The Four Tier Intervention Pyramid provides a framework for schools to ensure collaborative responses to student needs beyond classroom instruction. It establishes four tiers of intervention with Tier 1 being foundational classroom instruction, Tier 2 being interventions provided by the classroom teacher, Tier 3 being supports from other professionals, and Tier 4 being individualized intensive interventions that may include outside resources and diagnostic testing. The pyramid is intended to articulate differentiated strategies across classrooms and support inclusive practices.
