Multi-Tiered System of Support (MTSS)

Multi-Tiered System of Support (MTSS) - a term related to Response to Intervention. Sometimes the terms are used interchangeably, but the approaches differ in several ways. Among several distinctions between the two approaches is that MTSS emphasizes a system-wide responsibility for student support at all grade levels and throughout the district or state. Meanwhile, RtI can be implemented at any level (classroom, grade, or school, district).
