"As an external resource, the registry would help our employees find the kind of training they need that uses the modality that helps them learn best. It would be a win-win, for our employees and AT&T."
- Eric V. Mitchell, Assistant Vice President - Talent Optimization, AT&T

About Us


Credential Engine is a 501C3 non-profit organization whose mission is to improve transparency in the credentialing marketplace. Credential Engine pursues this mission by maintaining the open-licensed Credential Registry (CR) and Credential Transparency Description Language (CTDL), and promoting an open applications marketplace.


Credential Engine grew out of the Credential Transparency Initiative (CTI), which began in 2013. Supported by Lumina Foundation, CTI was led by the George Washington University’s Institute of Public Policy (GWIPP), Workcred – an affiliate of the American National Standards Institute, and Southern Illinois University (SIU) Carbondale’s Center for Workforce Development. CTI worked closely with an Executive Committee, a Technical Advisory Committee, and hundreds of diverse stakeholders in credentialing that provided feedback focused on three components: (1) development of the Credential Transparency Description Language (CTDL), (2) development of a prototype Credential Registry, and (3) development of a prototype app built on the registry (WorkitTM).

Collaborating and Harmonizing

Credential Engine connects with and complements other credentialing initiatives currently underway to improve the credentialing marketplace. Connecting Credentials is one example with close alignment. Our technical work also promotes collaboration and harmonization of standardization initiatives to identify, document, and openly share solutions supporting the comparability of credentials and competencies.
