To differentiate instruction is to act on the belief that all kids deserve access to the richest, most compelling learning experiences and to provide the scaffolding they need to seize that opportunity. While a handful of teachers in a school might be using differentiation to great success, it takes a collaborative, schoolwide approach to maximize differentiation's effectiveness and improve outcomes for all students. Leading for Differentiation lays out the reflective thinking and action-oriented steps necessary to launch a system of continuous professional learning, culture building, and program assessment that will allow differentiation to take root and flourish in every classroom.
