Avoca District 37 Multi-Tiered System of Support (MTSS) Definition:
Multi-Tiered System of Support (MTSS) is a whole-school, prevention-based framework that is focused on improving learning outcomes for every student through a layered continuum of evidence-based practices and systems that provides access to increasingly intense levels of instruction & interventions.

At full implementation, a robust multi-tiered system of support (MTSS) should be a system of stakeholders collaborating regularly to:
- Identify and respond to diverse student behavioral and learning needs
- Empower students to learn in the least restrictive environment possible
- Empower staff to deliver high quality instruction in the least restrictive environment for students.
