This session introduces K–5 classroom teachers, special education teachers, and instructional coaches to the core concepts of how to use data from different assessments to make instructional decisions. Participants will explore the essential components of a Balanced Assessment System and develop a clearer understanding of how different types of assessments work together to support student learning within a Multi-Tiered System of Supports (MTSS). During this session, educators will examine the purpose of key assessment types (e.g., screening, formative, and progress monitoring) and how each answers critical instructional questions. Participants will engage in brief reflection activities to consider how assessment data is currently used in their classrooms or systems and identify opportunities to strengthen alignment and decision-making practices. This session is designed to build foundational awareness with an overview of using data to make instructional decisions.
