MTSS Tier 1 provides the high-quality instructional foundation that every student receives every day. At its core is effective whole-class instruction supported by research-based practices, including student engagement, formative assessment and feedback, scaffolding and interventions, depth and rigor, positive relationships and classroom climate, differentiation through flexible small groups, and effective classroom instruction. This instructional framework is strengthened by schoolwide systems such as attendance initiatives, culturally responsive practices, and PBIS, creating a safe, supportive, and equitable learning environment. Together, these elements establish a strong foundation that promotes success for all students before more intensive interventions are needed.
