The Equity in IDEA regulations require states to determine annually if local education agencies (LEAs) are identified with significant disproportionality. The regulations outline specific requirements related to methods for identifying LEAs and activities the LEAs must complete after they are identified. These significant disproportionality resources can assist states with implementing these requirements and supporting LEAs through the process of meeting the requirements.
