Differentiation is essential—but too often, it feels overwhelming or inconsistent across classrooms. This session reframes differentiation as efficient, strategic, and sustainable by integrating the use of proficiency scales—a foundational component of Dr. Robert Marzano’s High Reliability Schools (HRS) framework. Participants will explore how proficiency scales bring clarity to learning goals, support student agency, and streamline differentiation to ensure every student progresses—regardless of where they begin. Through a blend of research-based practices and real-world examples, attendees will leave with tools and strategies they can immediately use to strengthen instruction and equity on their campuses.
