This TA guide addresses the more common methods for calculating racial/ethnic disproportionality in special education. IDC revised the guide, which the Data Accountability Center (DAC) originally published in October 2011, because of a change in SPP/APR Indicators 9 and 10 to remove underrepresentation from the measure.
The TA guide can be used by state agency staff who make decisions regarding their state's disproportionality analyses and those who analyze disproportionality data or interpret the results of those analyses. Many methods for calculating disproportionality exist. Each method answers a somewhat different question about racial/ethnic disproportionality in special education. The TA guide describes some of the more common methods, summarizes the question each method answers, provides step-by-step examples of how disproportionality is calculated, and offers brief discussions of how to interpret the method and some considerations.

Format: PresentationsEquity, Inclusion, and Opportunity: Addressing Success Gaps via the SSIP Process
Presenters introduced a research-based guidance document and self-assessment rubric designed by OSEP's Disproportionality Priority Team to help districts and schools identify the root causes of "success gaps" for some groups of students, thereby helping to improve and equalize results for all students. As an example, presenters used Georgia's SSIP process, focused on graduation for students with disabilities.

The presentation introduces a research-based guidance document and self-assessment rubric designed to help districts and schools identify the root causes of "success gaps" (for example, in test scores, suspension or graduation rates, or course credits) for some groups of students, thereby helping schools to improve and equalize results for all students.
Format: Guides and BriefsSuccess Gaps Rubric: Addressing Equity, Inclusion, and Opportunity
This rubric allows a team of users from a district or school to systematically examine the root causes of success gaps among groups of students by focusing on equity, inclusion, and opportunity. The recently updated rubric now includes considerations for children as young as preschool age. A complementary white paper provided the research-based background that supported development of the rubric.
Format: Guides, Papers, and ReportsEquity, Inclusion, and Opportunity: Addressing Success Gaps, White Paper
This white paper focuses on elements of equity, inclusion, and opportunity that can minimize or eliminate success gaps among different groups of students. It provides the research-based background that guided development of a complementary rubric that schools or districts can use to systematically examine the root causes of success gaps among groups of their students. The white paper has been updated recently and now includes considerations for children as young as preschool.
