Persistent achievement gaps by race and class in U.S. public schools are educationally and ethically deplorable and, thus, need to be eliminated. Based on their research on schools and districts that haven arrowed these gaps, the authors have developed a simplified reconceptualization of equity auditing, a concept with a respected history in civil rights, in curriculum auditing, and in some state accountability systems. This reconceptualized equity auditing is a leadership tool that can be used to uncover, understand, and change inequities that are internal to schools and districts in three areas--teacher quality, educational programs, and student achievement.
