As the charter school sector expands rapidly with federal support amid on-going diversification and growing segregation among traditional public school students, this article examines existing patterns of segregation in charter schools. Prior research has demonstrated that charter schools are substantially more segregated than our already stratified public school system. This article uses national data from 2007-08 and finds that charter schools are indeed more segregated for students of all races. We pay particular attention to these trends in suburban areas and at the metropolitan level where charter schools could be institutions that create diversity across city-suburban or intra-suburban boundary lines. It concludes with a discussion of why these patterns may exist and what could be done to remedy segregation. (Contains 5 footnotes.)
