Significant Disproportionality

December 2016, federal regulations regarding significant disproportionality were updated. States were required to update their policy and procedures to better understand the extent of disproportionality and promote consistency among states. This website will provide information on South Dakota’s Significant Disproportionality Methodology, federal documents and other information relevant to school districts.

Delay of implementation to July 1, 2020 (see federal regulation final rule)

Disproportionality exists when students in a racial or ethnic group are more likely to be:

  • identified as a student with a disability
  • identified as a student with a particular disability
  • placed in more restrictive settings
  • suspended or expelled
  •      ...than students in other racial or ethnic groups
