Multi-Tiered System of Support

Multi-tiered system of supports (MTSS) is a coherent continuum of system-wide, data-based problem solving practices supporting a rapid response to the academic and behavioral needs for all students. This comprehensive system of supports includes assessments (universal screening, diagnostic, progress monitoring, formative, and summative), research-based instruction, and interventions. This instruction/intervention is delivered across multiple tiers dependent on the individual student needs identified by student outcome data (ADE, 2022).
