Educational segregation is the systematic separation of students into distinct educational settings or tracks based on demographic characteristics such as race, socioeconomic status, disability, or language proficiency. This concept, as a field of academic inquiry, investigates the historical and contemporary patterns, structural causes, mechanisms of reproduction, and multifaceted consequences of such separation, including its impact on resource distribution, educational quality, student outcomes, and social stratification. Its significance lies in illuminating persistent inequalities within educational systems and informing efforts toward equity and desegregation.
