February CTDL Release

Dear CTI/Credential Engine Technical Advisory Committee and Partners,

A Credential Transparency Description Language (CTDL) release will occur on Friday, February 24, 2017. This release follows the initial release on November 11, 2016. Following the CTDL release policy, all updates for the February release are now available for TAC and partner review via the CTDL Pending page. This web page shows all of the CTDL classes, properties and concept schemes that are ”Stable”, “Unstable” and “Pending.” All items with a status of “Pending” are scheduled for release on Feb. 24th and will change to a status of “Stable.”

To filter to see only “Pending” items:

  1. Go to
  2. In the footer at the bottom of the window, select to filter by clicking on “Show Pending.”
  3. Scroll down the page to see all classes, properties and concept schemes with a status of Pending.
  4. To see the details of each pending item, click on the term’s panel. This will open the panel to show all of the related information.

If you have any comments about the CTDL schema items marked as “Pending” please either use the TAC Google Group or email Comments need to be submitted by Wednesday, February 22, 2017.

This same process will be followed for all subsequent releases. Also, on the day of the release, a History page on the website will be updated to show all updates from “Pending” to “Stable” as well as other updates such as deprecations. The team will send an email and update the Google group on the day of the release to include direct links to the information about the CTDL release such as the change history. The CTI/Credential Engine (CE) team appreciates your review and comments.


Sincerely, CTI/CE Technical Team

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.

Learn More


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.
