This study examines the relationship between segregated education and school outcomes fbr African American adolescents in the Charlofte-Mecklenburg, North Carolina, school district (CMS), regarded as a model of successful desegregated public schooling. Using 1997 survey data, it investigates the effects of segregated elementary education and racially identifiable tracked secondary courses on the academic achievement of 640 African American high school seniors. Findings indicate that many CMS schools remain segregated at the building level; at the secondary level, all core academic classes were tracked and racially identifiable, with Black students disproportionately found in lower tracks. Both forms of segregated schooling had negative effects on academic outcomes. Importantly, desegregated learning environments benefited the academic performance of Black students who experienced them.
