The document discusses the Multi-Tiered System of Supports (MTSS) framework. It explains that MTSS aims to provide an integrated systemic approach to meeting the needs of all students using resources efficiently. MTSS involves reviewing current practices, addressing gaps, and replacing ineffective approaches with evidence-based practices. The framework provides different tiers or levels of support including core instruction for all students, supplemental instruction for some students, and intensive interventions for few students.
