Schools often struggle to determine whether a student’s difficulty stems from a lack of skill acquisition or inconsistent performance. Misidentifying the problem leads to ineffective interventions, frustration, and delayed student progress. This session provides educators with a practical framework for distinguishing acquisition versus performance issues within the Multi-Tiered System of Supports (MTSS). Participants will learn how to analyze data, ask the right diagnostic questions, and match interventions to student need. Through real-world examples and interactive case studies, attendees will leave with tools they can immediately apply during MTSS team meetings and classroom problem solving.
