Multi-Tiered System of Supports (MTSS)

About MTSS

MTSS is a framework applied at the state, district, and school level that uses implementation science to create one integrated system. This system is designed to support the needs of all students. MTSS is defined as a prevention-based framework of team-driven data-based problem solving for improving the outcomes of every student through family, school, and community partnering and a layered continuum of evidence-based practices applied at the classroom, school, district, region, and state level.


MTSS Essential Components

MTSS consists of 5 essential components. Please click on each link below for more information on each component:

  1. Team-Driven Shared Leadership
  2. Data-Based Problem Solving and Decision-Making
  3. Family, School, and Community Partnering
  4. Layered Continuum of Supports
  5. Evidence-Based Practices

At the district or regional level, leadership teams build infrastructure that supports the implementation of the 5 components of MTSS. The building of this infrastructure includes (1) identifying and aligning key priorities, (2) securing funding, resources, and time to implement those priorities, (3) developing training and coaching structures to support personnel with implementation, and (4) gathering data to evaluate the implementation and impact of the key priorities.

At the school level, building teams implement their identified priorities and build a tiered system that fits their respective context. School teams identify the fidelity and student outcomes they wish to achieve and then identify the data needed to monitor progress toward those outcomes. They also outline the practices used at each tier, as well as the systems that enable staff to both implement the identified practices and to gather the required data.
