The Mechanism of State Charter School Policy Adoption: The Case of American States

This article concentrates on charter school policy that is regarded as the fastest growing innovative policy in America. Its adoption is more impressive than other innovative policies in the public educational area. By 2008, 40 states among 50 American states have passed charter school law since Minnesota became the first pathfinder to create charter school law about two decades ago. However, 10 states have not adopted charter school law. Based on this dichotomous policy phenomenon, the primary research question of the study focuses on clarifying what factors drive American states to adopt charter school policy. To obtain answers for this research question, the study dedicates to analyzing main hypotheses from the regional diffusion model and state characteristics, using event history analysis. The results demonstrate that the three predictor variables—regional diffusion, similar innovation, and gubernatorial political tendency—positively have significant effects in explaining the adoption of American state charter school policy.
