TY - JOUR AU - Coburn, Cynthia E. AB - The issue of “scale” is a key challenge for school reform, yet it remains undertheorized in the literature. Definitions of scale have traditionally restricted its scope, focusing on the expanding number of schools reached by a reform. Such definitions mask the complex challenges of reaching out broadly while simultaneously cultivating the depth of change necessary to support and sustain consequential change. This article draws on a review of theoretical and empirical literature on scale, relevant research on reform implementation, and original research to synthesize and articulate a more multidimensional conceptualization. I develop a conception of scale that has four interrelated dimensions: depth, sustainability, spread, and shift in reform ownership. I then suggest implications of this conceptualization for reform strategy and research design.
