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.

Digital Credentials Initiatives Monitor
Try out the Version 0.5 of the new Digital Credentials Initiatives Monitor, a visualisation tool to explore the range of technology models offered around the world.
This platform provides information on the types of technology in use, the standards, the governance, and more. If you are interested in helping to grow this tool, please fill out our online survey. Your results will be uploaded to the database on a monthly basis.
Thanks are extended to the German Academic Exchange Service (DAAD), GDN and UNESCO which jointly initiated this visualisation and the German Foreign Office for providing project funding. Particular mention is extended to Alsino Skowronnek, who designed and programmed the tool.;
The platform was launched at the GDN 2022 meeting in Groningen, Netherlands. Watch the presentation at the GDN Annual Meeting here.
