Multi-Tiered System of Support (RtI, PBIS, SEL)

Multi-Tier System of Support (MTSS)

MTSS is the practice of systematically providing differing levels of intensity of support based on student responsiveness to instruction and intervention in academics and behavior. All students are supported through this structure of supports and instruction. Within WSD schools, the multi-level system of support is a three-tiered structure of support designed to maximize student achievement in the general education setting. 


Response to Intervention (RtI) is an organizational framework that guides implementation of a multi-level system of support to achieve academic and behavioral success for all. The RtI framework includes three essential elements:

  • high quality instruction (in academics and behavior)
  • balanced assessment
  • collaboration among staff and families

RtI is in the process of being implemented in WSD schools around literacymathematics and also in behavior through the PBIS framework which closely mirrors the traditional RtI framework for addressing student needs. 

Schools are encouraged to stay up-to-date with best practices and share success stories across the district from various schools.

These three essential elements, embedded with culturally responsive practices and family engagement, both supported by leadership and organizational/ team structures, interact within a multi-level system of support. 

RtI Framework Key Components & Useful Links 

The Response to Intervention Framework is designed to reach all students. In a healthy RtI framework for academics or behavior schools must consider: culturally responsive practices, English Language Learners, students and trauma, students with disabilities, gifted and talented in order to ensure reaching all students.
