MTSS stands for
multi-tiered system of supports. It’s a framework many schools use to give targeted support to struggling students. You may also hear it called the MTSS framework, the MTSS process, or the MTSS model.
MTSS is designed to help schools identify struggling students early and intervene quickly. It focuses on the “whole child.” That means it supports academic growth, but many other areas, too. These include behavior, social and emotional needs, and absenteeism (not attending school).
