Decades after the Brown v. Board of Education ruling banned mandatory race-based separation of students to different schools, school segregation, and inequality in the United States are rapidly increasing. In this research synthesis, I propose a model for explaining how segregation and inequality are formed in urban and suburban school systems and exacerbated even in the absence of formal segregation policy. The model describes segregation as a component in a triangle of discriminatory education policy processes: segregation, discrimination, and signaling. Connecting these three seemingly distinct policy practices could provide a better explanation for the growing inequality in the U.S. school system.

在 Brown v. Board of Education 裁决禁止基于种族的强制性将学生分到不同学校后的几十年里，美国的学校隔离和不平等正在迅速增加。在本研究综合中，我提出了一个模型来解释隔离和不平等如何在城市和郊区学校系统中形成，并在没有正式隔离政策的情况下加剧。该模型将隔离描述为歧视性教育政策过程三角中的一个组成部分：隔离、歧视和信号。将这三种看似截然不同的政策实践联系起来，可以更好地解释美国学校系统中日益严重的不平等现象。
