MTSS & Intervention Services
Multi-Tiered Systems of Support (MTSS) is a process that aids students' educational development by including universal screening of all students, multiple tiers of instruction, support services, and an integrated data collection and assessment system. The Intervention Services Team seeks to provide high-quality support to students who have experienced difficulties with learning, are at risk of dropping out, and have a physical or mental impairment.
