Multi-Tiered System of Supports (MTSS)

  •  Students are sitting on a carpet facing a teacher who is sitting next to a white board pointing at a chart.       Often referred to as the “way we do business" in schools, MTSS is an organizational framework intended to improve outcomes through the effective collaboration of adults.

    The framework utilizes high quality evidence-based practices to provide the level of support needed for each educational stakeholder and for the whole system (i.e., classroom, school, program, or district). With MTSS, schools and districts integrate and align academic standards, behavioral expectations, and adult activities. Because MTSS is a comprehensive, continuous-improvement framework, data-based problem solving and decision-making is practiced across all levels - by each and every stakeholder within the system.  


    Within Colorado, the evolution of responsive learning frameworks has led to the current understanding of MTSS. An important guiding principle is the focus on prevention. By setting up systems and structures that reduce or remove learning challenges or operational barriers, MTSS enables each stakeholder to benefit from a safe and supportive environment. The Thompson School District (TSD) aligns its implementation of MTSS with the description from the state.

    The Colorado Department of Education (CDE) defines MTSS 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. (CDE, 2016)

    This definition asks that the district functions as one system, with many sub-systems and many supports included. That means that a school district's resources, personnel, and operations should help ensure success within each school. The schools, then, are able to direct and coordinate all of its resources and strategies to secure access, opportunity, and educational benefit in each learning experience.

    In TSD, the plan is to implement MTSS with fidelity and to sustain it over time. That priority has been named in Strive 2025 (the TSD strategic plan), and that belief will help shape the approaches that are adopted for use within the district. Through the effective application of implementation science and the active engagement of each stakeholder, TSD will prepare students for any pathway - for college, career, and life


    Because there have been different understandings about MTSS, some confusions exist about what MTSS is and what value it can offer to educational  systems. For example, MTSS has been described as replacing Response to Intervention (RtI) or Positive Behavioral Interventions and Supports  (PBIS), or serving as the combination of the two - without clarity about what that means or how things are connected. In actuality, both RtI and PBIS have identities within the MTSS framework, but there is more to MTSS than that.

    And in many ways, it is simple and clear; MTSS is the what and the how.
    It is the WHAT - as in, it is a batch of puzzle pieces, each with its own curves, colors, and connectors
    ...and MTSS is also the HOW - as in, MTSS helps make sense of each puzzle piece, linking them all together in a pattern where each piece contributes to a complete picture

    MTSS is the parts AND the whole!
