Integrated Multi-Tiered System of Supports (I-MTSS)

Pennsylvania’s Integrated Tiered System of Supports is a framework that unifies general and special education services across Tiers 1, 2, and 3 to ensure equitable access to high‑quality instruction and timely support for every student’s learning, behavior, and well‑being. The system emphasizes prevention, early intervention, and data‑informed decision making. Schools collaborate by sharing responsibility, using evidence‑based practices, partnering with families, and working as a team to create coherent, aligned supports that prepare students for success in school, work, and life.
