According to McIntosh & Goodman (2015), a multi-tiered system of support (MTSS) is an integration of a number of multi-tiered systems into a single, coherent, strategically integrated system to address multiple domains in education (behavior, social-emotional, academic). MTSS is a decision-making framework used to guide the selection and implementation of best practices for improving academic and behavioral outcomes. Through this framework, leadership teams across all implementation levels (state, district, and school) use core implementation elements to improve the learning environment for all students.

SSD's MTSS Facilitators have created the following foundational guide for installing and maintaining MTSS within your district or building. It's intended purpose is to support district and school-level teams, coaches, and staff on the rationale and best practices to build and sustain MTSS focusing on behavior and social emotional learning.
