About Credential Registry

Credential Registry allows users to see what various credentials represent in terms of competencies, transfer value, assessment rigor, third-party approval status, and much more.

The open and voluntary registry will include all kinds of credentials, from education degrees and certificates to industry certifications, occupational licenses, and micro-credentials. Each credential will describe its name, type, level, competencies, assessments, accreditation, labor market value, and so on.

The goals are transparency and clarity, and to help align credentials with the needs of students, job seekers, workers, and employers.

Get Started Now


The Credential Engine project’s technical team (TT) provides credentialing pilot site partners with a set of services beneficial to each organization’s short- and long-term technology planning.

Through each phase of the Credential Engine project, the TT provides assistance, including non-technical and technical materials for administrators and technical staff.

Throughout the process, partners provide information and access needed to co-engineer the Credential Registry, Credential Directory, and other potential apps. Pilot site partners are also discovering the benefits of linked data, and providing iterative feedback on the process and outcomes.

Developers are able to leverage the the Credential Registry API to build applications that can read or publish as much or as little information about credentials as they need to.

The Credential Engine project's developers are using Dublin Core Application Profiles process to create sytems that communicate all virtually all aspects of credentials.

Technical Advisory Committee

The Technical Advisory Committee (TAC) promotes collaboration across, and harmonization of, standardization initiatives that are developing data models, vocabularies, and schemas for credentials and competency frameworks, and related competency information such as criticality ratings and assessment data typically captured with a wide variety of systems.

The goal is to identify, document and openly share solutions that support comparability of credentials and competencies across industries/sectors, human resource systems, education, and government systems.
