This Success Gaps Rubric: Addressing Equity, Inclusion, and Opportunity, hereafter referred to as Success Gaps Rubric, is designed to help any school district or school identify the root causes for success gaps, which are gaps in performance between groups of children in a district or school. The rubric uses the term children because, although the children may range in age from preschoolers through students at the end of secondary school, addressing the success gaps is the responsibility of the adult professionals in the district or school, not the children. The rubric is part of the larger Success Gaps Toolkit: Addressing Equity, Inclusion, and Opportunity, hereafter referred to as Success Gaps Toolkit, located on the IDEA Data Center (IDC) website.
