The Excel spreadsheet application and user's guide are tools to aid states in their assessment of racial/ ethnic disproportionality. The spreadsheet application calculates several disproportionality measures, including risk, risk ratio, weighted risk ratio, alternate risk ratio, risk difference, composition, difference in composition, relative difference in composition, the E-formula, and variations of several of these measures for total disciplinary removals. The user’s guide includes an overview of the spreadsheet application; discussions on data requirements such as data formats, district identifiers, missing data, and state totals; and instructions for using the spreadsheet application including opening the spreadsheet application, entering data, running the spreadsheet, and reviewing results. The final section of the user’s guide addresses how to handle questions or problems.
IDC ’s technical assistance document, Methods for Assessing Racial/Ethnic Disproportionality in Special Education: A Technical Assistance Guide (Revised) provides more information about the measures calculated by the spreadsheet, including step-by-step instructions on how to calculate them, discussions of how to interpret each, and considerations.

Format: Guides and BriefsMethods for Assessing Racial/Ethnic Disproportionality in Special Education
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.
