Under Michigan's Dyslexia Legislation, the Multi-Tiered System of Support (MTSS) serves as the comprehensive framework for identifying and supporting students who exhibit characteristics of dyslexia or experience difficulty reading. The law requires that these systemic supports be whole-child oriented, aligning with the MiMTSS model's focus on integrating academic, behavioral, and social-emotional needs within a unified structure. Specifically, the legislation mandates a three-tiered delivery system where Tier 1 provides evidence-based, code emphasis instruction grounded in the science of reading for all learners, while Tier 2 and Tier 3 offer increasingly intensive, data-driven interventions for those needing specialized support. By the 2027-2028 school year, districts must ensure their MTSS infrastructure includes professional learning for staff on dyslexia and the use of valid screening assessments to inform continuous, team-based decision-making.
