Digital Credentials Consortium (DCC)
VisionCreate an education landscape that increases learner agency andpromotes more equitable learning and career pathways

MissionCreate a trusted, distributed, and shared infrastructure that is
the standard for issuing, storing, displaying, and verifying digitalcredentials

What’s a Digital Credential?
● A “digital credential” — a data-based digital representation of a
diploma, degree, program certificate, workshop certificate

Name of credential, name of recipient, university
name, date issued, perhaps a description

Guiding Principles | ValuesLearners - Commitment to learner agency and participation● Learners retain primary control over their credentials
Issuers - Commitment to issuer control of the design of the credential● Issuers control to whom they issue credentials, the particularachievement that the credential represents, and which credential
options are available to the learner
Trust - Commitment to open processes, open standards, and software● Credentials can be verified without consulting original issuer

How does DCC do its work?
● Develops open standards, open source reference libraries, core
infrastructure services○○○○
