Multi-Tiered System of Supports (MTSS) is a framework for integrating levels (or tiers) of academic and behavior support to promote the success of all students. Sometimes referred to as RTI, or response to intervention. The ultimate goal of a MTSS is to provide high-quality instruction and the degree of support each student needs to be successful. MTSS is not a special program, class, or intervention, but rather a way of organizing instruction and intervention to help all students and promote early identification of students needing additional academic or behavioral support to be successful. MTSS is also used to help identify students who may need special education.
