About the Collection: Educator Data System (EDS)
The Educator Data System (EDS) collects data on all Connecticut public school educators and all educators in approved private special education programs (APSEPS) for each of the roles that they hold. Educators to be reported include all certified staff and all staff who do not currently hold certification but are in roles that require certification. These data will be matched with the Connecticut Educator Certification System (CECS) and other data collected by the Department (e.g. TCS, DM, and others). The Certified Staff data are used for several purposes including:
- Federal and state reporting
- Public reporting
- Certification compliance and successful service validation
- Educator Equity Analyses
- Registration in the TEAM program
- Validation of Teacher-Course-Student (TCS) data
Important Dates*:
The EDS is a rolling data collection. Changes are expected to be reported throughout the school year as staff take leaves, are promoted and/or transferred, are hired and/or leave your district. As data are used at different times during the year, it is critical that the staff data be kept up-to-date. One of the uses that is of particular importance is the October 1 Reporting Extract. This file is used for both federal and state reporting and is often part of public data requests.
