A key strategy to realizing the vision of closing opportunity gaps in Washington is a comprehensive Multi-Tiered System of Supports (MTSS) framework. A framework for enhancing the adoption and implementation of a continuum of evidence-based practices to achieve important outcomes for all students.
The components of the MTSS framework represent the combination of Response to Intervention (RtI) and Positive Behavioral Interventions and Supports (PBIS). Implementation science guides the strategic application of MTSS.
