The definition of MTSS can vary, especially as states develop and define their own MTSS processes to comply with the Every Students Succeeds Act. By and large, MTSS is a framework for identifying students who need support, making data-driven decisions, implementing research-based interventions aligned to needs, monitoring student progress, and involving stakeholders. In other words, there are many overlapping elements with Response to Intervention (RtI).

MTSS Overview
What is MTSS?
The multi-tiered system of supports (MTSS) framework can be considered the umbrella for other support systems, such as data-based individualization (DBI), response to intervention (RTI), and positive behavior intervention and supports (PBIS). MTSS encompasses academic, behavioral, and mental health supports for all students.
Students in general education and those receiving special education and related services can participate in MTSS. MTSS is not used to delay or deny a child’s right to an initial evaluation for special education and related services.
A primary component of MTSS is using assessment data to drive differentiated instruction and decision making for all students. Through MTSS, schools identify students in need of additional support and provide these students with evidence-based intervention to reduce academic and behavioral gaps.
MTSS promotes collaboration among teachers—both general education and special education—and support specialists. MTSS also helps schools effectively communicate student progress to caregivers.
