MTSS (Multi-Tiered System of Supports) is a comprehensive framework for school improvement that integrates data-driven decision-making, evidence-based practices, and a tiered system of support to address the academic, behavioral, and social-emotional needs of all students. The goal of MTSS is to ensure that every student receives the right level of support at the right time through proactive and targeted interventions, continuous monitoring, and collaborative problem-solving among educators, families, and other stakeholders.
