This rubric can help schools or districts address success gaps that exist between groups of their students, such as gaps in test scores or graduation rates between students with disabilities and other students. The rubric allows a team of users from a school or district to systematically examine the root causes of a success gap by focusing on elements leading to equity, inclusion, and opportunity. The rubric has been updated and now includes considerations for children as young as preschool. A complementary white paper provides the research-based background that supported development of the rubric. State and local staff can contact their IDC [IDEA Data Center] state liaisons for information on how the rubric can be modified to meet their state-specific needs.
