Many districts have adopted high-quality instructional materials (HQIM) for mathematics, but strong materials alone do not guarantee strong implementation. District leaders need coherent systems, shared measures, and a common language to help principals, coaches, and teachers turn new curricula into consistent classroom practice.

This brief from WestEd draws on interviews with math leaders in 11 districts across seven states to show how they are building those systems for middle school HQIM. It surfaces what is working, including materials that support overstretched teachers and shift classrooms toward conceptual understanding, along with the implementation data, pacing supports, and curriculum-anchored professional development that make practice visible and aligned. District and system leaders will find practical guidance and shared measures for stronger implementation.
