Schools and districts continue to grapple with problems related to effectively addressing equity. Part of Center for Education Equity's (CEE's) "Exploring Equity Issues" series, this paper provides an overview of how education leaders collect and use data to address questions related to equity, identify the root causes of their problems, and make decisions to implement change. Finally, there is a discussion on the need to examine how school district's policies and practices may limit the access and opportunities for some students, particularly students of color and those living in poverty.
