Expert answer
A multi-tiered system of supports (MTSS) is a proactive and preventative framework that integrates data and instruction to maximize student achievement and support students social, emotional, and behavior needs from a strengths-based perspective.
MTSS offers a framework for educators to engage in data-based decision making related to program improvement, high-quality instruction and intervention, social and emotional learning, and positive behavioral supports necessary to ensure positive outcomes for districts, schools, teachers, and students. Depending on state law, MTSS data may also support identification of students with learning or other disabilities.
The MTSS framework is comprised of four essential components: screening, progress monitoring, multi-level prevention system, and data-based decision. Learn more about each of the essential components of MTSS at the Center on Multi-Tiered System of Support .
