The Ed-Fi Unifying Data Model is the widely adopted, CEDS-aligned, open-source data standard developed by the educational community for the betterment of the community. The Unifying Data Model captures the meaning and inherent structure of the most important information in the K–12 education enterprise.

The Ed-Fi Unifying Data Model, along with the normative and non-normative guidance in the Ed-Fi Standards, serve as the foundation for enabling interoperability among secure data systems.
