Legacy EPDM Extension Versions
The pages in this section document the EPDM extension versions that existed prior to Ed-Fi Data Standard v6. Starting with Data Standard v6 (November 2025), the Educator Preparation Data Model is fully integrated into the Ed-Fi core standard and is no longer a separate extension.
For current documentation, see:
Background
Before Data Standard v6, EPDM was distributed as two separate ODS/API extensions:
- EPDM Community — The full-featured extension supporting broad use cases, including statewide implementations. Versioned independently from the core ODS/API.
- EPDM Core — A streamlined subset of foundational entities bundled directly with the ODS/API platform.
These extension versions are preserved here for reference by organizations maintaining older implementations or performing historical comparisons.
