Niles Elementary School District 71 uses a Multi-Tiered System of Support (MTSS), which the National Center on Response to Intervention defines as a prevention framework that organizes building-level resources to address each individual student’s academic and/or behavioral needs within intervention tiers that vary in intensity. MTSS allows for the early identification of learning and behavioral challenges and timely intervention for students who are at risk for poor learning outcomes. It also may be referred to as a multilevel prevention system. The increasingly intense tiers (Tier 1, Tier 2, Tier 3), sometimes referred to as levels of prevention (i.e., primary, secondary, intensive), represent a continuum of supports. Response to Intervention (RTI) and Positive Behavioral Interventions and Supports (PBIS) are examples of MTSS.
