Technical Services and Advisory Group

Technical Services

We specialize in helping organizations define, implement, and derive value from general open data strategies as well as from the Credential Registry and other Credential Engine services. Our areas of focus include credentials, skills and competencies, education and career pathways, transfer value, and quality assurance.

Advisory Group

The TAG is open to anyone interested in participating with feedback on development of the CTDL and other Credential Engine technologies and services and with supporting alignment with other standards.


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 systems that communicate all virtually all aspects of credentials.

Use the CTDL Schemas

The Credential Transparency Description Language (CTDL) is available to use with data design, with interoperable learner/worker records, and for publishing information as linked data.

Explore the CTDL Handbook, Terms, Serializations, ILWR Guide, and other resources for using CTDL on this site.

Publishing Options

Credential Engine offers the following options for publishing to the Credential Registry:

  • Registry Assistant Publishing API
  • Manual Entry
  • Bulk Upload

For more information on setting up your account and getting started with any of the publishing methods, click here.

Search Options

Credential Engine offers a robust search API to enable developers to leverage the wealth of data contained in the registry, using the CTDL and CTDL-ASN schemas.

Credential Engine offers a way for non-technical participants to enable a credential search on their own website. The Credential Finder Widget can be customized to match your site's theme and your preferences for automatic filtering, so that the results it shows can be more closely tailored to your site's purposes.

As you know, the CTDL is a continuously evolving language to meet new needs and use cases; as partners and experts in your field, we look to you to provide input and feedback as we consider new terms, definitions, and concepts. While we already have a Financial Assistance Profile, we have a proposal to update and organize it here.

Please review and provide feedback on the proposal no later than Friday, August 7, 2020. In particular, we are looking for input on:

Join new Credential Engine Task Groups
Posted on 6/30/2020

Credential Engine follows a process to make significant updates to develop the Credential Transparency Description Language (CTDL). This process includes subject matter and technical experts forming task groups to provide valuable input. You are invited to join one or both new task groups for Transfer Value or Education and Training to Jobs. These groups are open to anyone interested in contributing their subject matter expertise on these topics. You do not need to have technical experience with the CTDL to participate.

Each group will hold 3-5 separate meetings online and use Google Docs and Groups between meetings to provide input. Additional meetings may be added if the task groups determine them needed. The meetings will begin in July and conclude in September. Once you join a group, you'll receive an email concerning meeting dates.

The task groups are to develop the CTDL terms for:

  • Transfer Value
    • Now more than ever, people need to combine education and training from multiple sources in order to continuously re-skill and upskill in rapidly changing careers. Unfortunately, most people do not get the full benefit of transferring their learning achievements to apply to further education and career advancement.
    • This group will help develop the CTDL Transfer Value Profile terms that can be used by all types of organizations to signal value across all types of learning programs and credentials. The group needs participants to provide transfer value use cases and recommendations for how CTDL can support valuable transfer value “currency.” The group will provide required community review, validation, and feedback before making this new profile a permanent part of CTDL.

  • Education & Training-to-Jobs
    • With our rapidly changing economy, it’s critical to address the need to improve linking of education & training to jobs.
    • This group will help develop the CTDL job terms to be used to show the connections between education and training to credentials to jobs. Currently the CTDL can provide rich descriptions of connections to occupation classifications such as O*NET, but as our ever-changing economy has proven, we must also have explicit connections to jobs. This is not intended to describe resumes or Human Resource system content, but it will enable linking skills, competencies, credentials, learning opportunities, assessments and other opportunities to jobs. This means that credentialing organizations can better show connections to jobs and employers can better signal the credentials, skills, and competencies for jobs both in the Registry and on the Web.
