Significant Disproportionality

Regulation CRF 34 §300.646 of the Individuals with Disabilities Education Act (IDEA) requires each state receiving assistance under Part B of the IDEA provide for the collection and examination of data to determine whether significant disproportionality based on race and ethnicity is occurring in the local education agencies (LEA) of the state with respect to:

  • Special education identification
  • Discipline
  • Educational placement

In Michigan, an LEA is the intermediate school district (ISD). The Michigan Department of Education Office of Special Education identifies ISDs each spring based on data from the previous two school years. Identification is based on the aggregate data of the member districts within the ISD.
