A Multi-tiered System of Supports (MTSS) is a “tiered system of supports that integrates assessment and intervention within a school-wide, multi-level prevention system to maximize student achievement and reduce behavioral problems. MTSS promotes systems alignment to increase efficiency and effectiveness of resources” (Adopted from National Center on Response to Intervention, 2010).
