About the Collection: ED166

Welcome to the new ED166 Help Site. The ED166 is the Student Disciplinary Offense Data Collection. Each year districts are required to submit 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, the No Child Left Behind: Unsafe School Choice Option, Special Education Reporting and various other data requests.
This site contains all the information you need to successfully submit your districts ED166 Data. If there is any additional information you need or would like to see on this site please contact me and I am happy to help you. This site contains information for LEA's on how to report discipline data.
