Introducing the GDN T.R.U.S.T. Hub

Are you wondering who the GDN Signatories are? Are you wondering if a  credentialing platform or depository is part of the GDN network?  Have a look at the map below.

The GDN is proud of its ability to identify trusted entities through its Signatory process. Signatories are required to sign and demonstrate their commitment to the GDN Ethical Principles for data exchange to support learner and social mobility. Any organization’s application for  signatory status requires review and approval by the GDN Board of Directors. The criteria for becoming a Signatory are available here.

By using this map, you will get an overview of the GDN Digital Learner Data Ecosystem where the Signatories, including credential depositories, are located, and how to contact them for more information.

Network Credential Depositories

Each of the organizations identified in the T.R.U.S.T. Hub is a GDN Signatory. Those identified as credential depositories have been sanctioned by the primary data source (an issuing institution) or a government authority. If you engage with a GDN Signatory credential depository, you can be sure it is trusted.

The Groningen Declaration Network reserves the right of final approval for publication of information and the right to make any changes as necessary including removing information from the GDN Trust Hub.
