Multi-Tiered System of Supports (MTSS) is a comprehensive, evidence-based prevention framework. Within MTSS, multiple levels of supports are provided to support the academic, social, emotional, and behavioral development of all students. Through it, all students are given access to inclusive and equitable educational practices that minimize opportunity gaps. Data is used to differentiate core instruction and select appropriate interventions for students who need supplementary support. The progress of all students is monitored to determine the effectiveness of the supports provided and to change course when necessary. MTSS also supports the development of staff and school systems through professional development and collaboration among cross-departmental teams of school staff and leadership.
