Multi-Tiered System of Supports (MTSS) is a framework which promotes school improvement through engaging academic and behavior practices for all students, so that every student can achieve academic and life success. MTSS is a “whole child” approach that creates systems to improve student academic performance as well as behavior, attendance and social emotional learning. To create these systems, an MTSS must utilize four essential elements: screening, progress monitoring, a three-tiered instructional/intervention model, and data-based decision making.
