This article focuses on how parental school choices affect the degree of racial and academic segregation in charter schools. The research design allows for a direct comparison of the racial and academic conditions of the district schools students exited to the charter schools they entered. Parents choose to leave more racially integrated district schools to attend more racially segregated charter schools. Simultaneously, parents enroll their students into charter schools with at least the same degree of academic integration as the district schools that students exited. The academic and racial segregation results are then used to test the extent to which students congregate into specialized charter schools according to hypothesized patterns. The findings call into question the assertion of charter school advocates that segregated conditions in charter schools are the result of students self-selecting into specialized charter schools.
