This chapter in an edited book focuses on the work of two improvement network hubs in California as they tried to support participating districts and schools to improve the proportion of students “on-track” for post-secondary success. California has a particular stake in figuring out how to support districts in consistently using continuous improvement (CI) to achieve measurable gains in student outcomes because state policy (e.g., Local Control Funding Formula, California’s Every Student Succeeds Act Plan) prescribes CI as the approach to improvement in its accountability system.

This study uses qualitative case study methods to explore how educators establish system-wide continuous improvement capabilities and coherence for implementation, taking into consideration the local contexts. Educators use two bridging approaches to crafting coherence: weaving and stacking. The study contributes to understanding how leaders create shared meaning and practice in complex and dynamic educational systems. The implications for both research and practice are discussed.
