The Data Center for Addressing Significant Disproportionality

The Data Center for Addressing Significant Disproportionality (we pronounce it DEE-KAS-DEE) is dedicated to working with state and local education agencies to help build their capacity to identify and address significant disproportionality by more accurately collecting, reporting, analyzing, and using their IDEA data.

What Is Significant Disproportionality?

Significant disproportionality is a term used to describe a pattern where students from one or more racial and ethnic groups are identified for special education, placed in more restrictive educational settings, or disciplined at higher rates than their peers. Since 2004, the federal government has required states to collect and report data on significant disproportionality in special education by race and ethnicity.
