In this article I seek to answer the question, “When are racial disparities in education the result of racial discrimination?” To answer it I synthesize the social science research on racially correlated disparities in education. My review draws from the sociology, anthropology, political science, psychology, history, and education literatures. I organize explanations into six categories: biological determinism, social structure, school organization and opportunities to learn, family background, culture, and the state. I arrive at three answers. The first is a definition: Racial discrimination in education arises from actions of institutions or individual state actors, their attitudes and ideologies, or processes that systematically treat students from different racial/ethnic groups disparately or inequitably. The second answer is that while distinguishing racial discrimination from disparities may be an interesting intellectual, legal, and statistical challenge, the conclusion probably is less meaningful than social scientists and policy makers might hope. The third answer follows from the first two. I propose the following reformulation of the original question: “When are racial disparities in education not due to discrimination?” I argue that the reformulated question is more likely to bring solutions to the race gap than the original one. Even if we conclude that discrimination does not cause racial disparities in education, we should not conclude that schools have no role in addressing them. If public schools do not address educational disparities, then who or what institution will?
