Achievement data of African American, Hispanic American, and Caucasian students from racially segregated and racially integrated settings in an urban, Midwestern school district were analyzed to determine the effect of racial isolation on achievement within each racial group. In the district studied, achievement of students from segregated schools was not significantly different from the achievement of same race students from integrated schools. The study's results should encourage district officials and instructional leaders to look at those factors that have a positive impact on student achievement regardless of the level of racial isolation.
