In this presentation, Stephanie Dehghani explores how schools can develop and implement an effective Multi-Tiered System of Support (MTSS). Drawing on research and her experience at Templestowe Heights Primary School, Stephanie examines the importance of strong Tier 1 instruction, alignment across all three tiers, and using data-informed decision-making to support student learning. The presentation challenges common misconceptions about MTSS and shares practical insights into building a coherent, evidence-informed approach to supporting all students.
