IDEA Section 618(d) requires States to annually examine whether significant disproportionality based on race and ethnicity exists in their LEAs (in Colorado, Administrative Units). Having significant disproportionality means that students of a particular race/ethnicity are significantly more likely than their other-race peers to be identified as children with disabilities, identified with a particular disability category (e.g., Autism, Intellectual Disability), placed in a particular educational setting (e.g., separate classroom), or suspended/expelled as a disciplinary measure.

What happens after an AU is identified as significantly disproportionate?
When an AU is identified as significantly disproportionate, it must 1) identify the factors contributing to the significant disproportionality, 2) review, and if appropriate, revise policies, procedures, and practices contributing to the significant disproportionality, and 3) Set aside 15% of its IDEA Part B allocation for comprehensive coordinated early intervening services (CCEIS). The resources listed below address the required activities in more detail:
- Mandatory Comprehensive Coordinated Early Intervening Services (CCEIS) – Q&A and Allowable Usage of CCEIS Funds (PDF)
- Coordinated Early Intervening Services (CEIS) – Resources Step By Step (Center for IDEA Fiscal Reporting (Will open a new webpage))
- Available resources include a template for reporting students who received CEIS services and the File Layout and Definitions
- Review the 2022 Significant Disproportionality Workbook reference document (PDF)
