Examining Representation and Identification: Over, Under, or Both?

Significant disproportionality with regard to identifying children as children with disabilities or as children with specific disabilities is, by definition, overrepresentation. This resource clarifies what the term overrepresentation means and defines three related terms: over-identification, under-identification, and underrepresentation. This resource also provides several scenarios and initial guiding questions that show how the four terms are related. States can use their answers to the guiding questions, in conjunction with the Success Gaps Toolkit, to help identify and address the factors contributing to significant disproportionality (i.e., overrepresentation) within school districts.
