Multi-Tiered System of Support (MTSS)

Pennsylvania’s Multi-Tiered System of Support (MTSS) is a standards-aligned, comprehensive school improvement FRAMEWORK for enhancing all students' academic, behavioral, and social-emotional outcomes. Response to Intervention (RTI) refers to the methodology that is used to determine how slow is slow (rate of growth) and how low is low (student’s level of performance) as an alternative to ability-achievement discrepancy within the Specific Learning Disability (SDI) Determination process.

Cross-disciplinary teams at the district, school, grade, and individual levels use a problem-solving process to integrate evidence-based academic, behavioral, and social-emotional practices matched to student needs and with the fidelity of implementation. A continuum of support and services exists at all Tiers. It is undergirded by high-quality professional learning, cultural responsivity, partnership and meaningful family involvement, and dynamic decision-making that rests on reliable and valid data sources. Sustainability (transformational change) is the ultimate implementation goal of a Multi-Tiered System of Support (MTSS) and is very much contingent upon Leadership, Organization, and Competency.
