Policy responses to disparities in education have proven to be largely inadequate in reducing persistent differences in academic outcomes, commonly referred to as the achievement gap. In this article, we identify some of the ways in which the fragmented nature of public policy generally, and education policy specifically, has contributed to the problem. We draw upon research from a variety of disciplines to argue that the most effective way to address the broad array of social and economic conditions impacting low-income children and their families is through the adoption of an ecological approach, similar to those used in public health. In order for education policies to promote equity in academic outcomes, they must explicitly address the ways in which race, class, language, and culture, as well as implementation processes, reproduce and reinforce disparities in academic achievement. We propose a new, comprehensive framework for equity-based education policy that makes it possible to respond to the social and economic factors that impact, and often undermine, efforts to improve academic outcomes. An analysis of California's Local Control Funding Formula (LCFF) and interviews with senior county leaders allows the authors to draw connections to the new policy framework, generating recommendations for strengthening education policies like LCFF.
