It is well-documented that students of color, and other historically underserved students, have had less access to an equitable and supportive learning environment, perpetuating school failure and, too often, a school-to-prison pipeline that is difficult to escape. This report shows how a number of states are taking advantage of opportunities in the federal Every Student Succeeds Act (ESSA) to address these disparities, make schools more inclusive, and help all students succeed. It provides information on which states have committed in their ESSA accountability plans and school improvement efforts to use one or more of five measures (or "indicators") to diagnose and address sources of inequity and school failure and to support the success of all students. They are: (1) suspension rates; (2) school climate; (3) chronic absenteeism; (4) extended-year graduation rate; and (5) access to a college- and career-ready curriculum. The report explains how the data can be used to inform efforts to improve schools, highlights selected state approaches, and is accompanied by a series of online interactive maps that show which states are using which indicators and how they are measuring student performance on that indicator. "Making ESSA's Equity Promise Real" provides resources to help policymakers, educators, community members, and others effectively use the information from these indicators to identify policies and practices that can close gaps in opportunity and outcomes.
