The law does not square with people’s experiences of segregation and diversity. An empirical look at the legal system’s effectiveness in addressing school segregation reveals, from a practical perspective, that segregation persists and even surpasses levels before the civil rights movement. Yet, the legal system continues as though segregation is a thing of the past. Even more bizarre, the negative effects of racial and ethnic disparities in schooling are well documented, and the legal system compels itself to ignore much of them. To exacerbate matters, legal analysts increasingly interpret the law as a system that operates in a different world than the one documented by researchers who describe disparities and what could be done about them. For their part, researchers pervasively continue to document experiences without considering the legal system’s basic concerns. This book details the source of these gaps, evaluates their empirical and legal foundation, explains why they persist, and reveals what can be done about them.
