About the Collection: ED166


Welcome to the ED166 Student Disciplinary Offense Data Collection Help Site. Each year public school districts are required to submit specific incidents to CSDE. CSDE then uses this data to satisfy various federal mandates such as the Individuals with Disabilities Education Act, the Safe and Drug Free School Report, the Gun Free Report, Special Education Reporting, and various other data requests. The aggregate data is publicly available on EdSight

If you are a parent or other member of the community looking for discipline data, bullying, or other disciplinary information visit the Links page for helpful information as this site is intended for ED166 Application Managers.
This site contains the information needed to successfully submit ED166 Data. If there is any additional information you need or would like to see on this site, use the Contact Information provided to connect with CSDE.
