Technical Services and Advisory Group
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.
CTDL Advisory Group
The CTDL Advisory Group 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, LER Guide, and other resources for using CTDL on this site.
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.
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.

Credential Engine follows a clearly defined, open process to make significant updates to develop the Credential Transparency Description Language (CTDL). This process includes subject matter and technical experts forming short-term task groups to provide valuable input, typically through six online meetings over approximately 12 weeks. You are invited to join our new CTDL Certificates Task Group.
The CTDL already supports rich descriptions of numerous types of credentials including some types of certificates. Credential Engine has been asked by a number of United States-based partners to consider expanding the types of certificates that are described and included in the CTDL. Consequently, additional types of industry, vocational, career, technical, secondary, and postsecondary certificates that are embedded in programs or require successful passing of assessments need to be explored to determine if/how they should be defined within the CTDL. The CTDL Certificates Task Group will revisit the definition and framing of the term “certificate” and sub-classes of that term in order to accurately represent ecosystems’ needs. This specific Task Group will focus on U.S. based issuance of certificates but is open to any interested persons globally. See the current list of types of credentials including certificates.
The chartered Certificates Task Group (CTG) will generate use cases and determine a CTDL model and terms proposal for additional types of certificates and terms for describing them and their relationships to competencies, assessments, jobs, other types of credentials and other relevant entities can be integrated into CTDL. This information is also available via the Credential Engine Website.
Who: Prior knowledge of CTDL is appreciated but not required. Credential Engine encourages subject matter and technical experts from education, training, industry and business to join the CTG regardless of where in the world they work. Examples of the knowledge and experience we seek include:
- subject matter experts with knowledge or experience of developing, implementing, and/or approving industry, vocational, career, technical, secondary or postsecondary certificates and related programs;
- subject matter experts in the use of industry, vocational, career, technical, secondary or postsecondary certificates;
- subject matter experts in designing or implementing education and career pathways that include industry, vocational, career, technical, secondary or postsecondary certificates;
- technical experts with knowledge of existing standards or technical implementations for industry, vocational, career, technical, secondary or postsecondary certificate and related areas such as competencies, learning opportunities, and assessments.
When and Where: The Certificates Task Group is anticipated to begin on Wednesday September 27 , 2023, hold approximately six, one-hour bi-weekly meetings on the following dates at 11:00 am ET. See the World Clock for your time zone. All meetings will be recorded and materials will be shared with all SSTG members.

Resources: Credential Engine will create and provide all resources needed for this work, based on CTG input, and share them for ongoing feedback between meetings. All feedback and materials are transparently available following an open development process.
Outcomes: The final products of this work include the expanded use cases, real-world data examples, and relevant CTDL domain model and terms with definition, and data standards mapping. All outputs from the process are all public information made available under open licenses.
Processes: The process utilized to ensure timely and usable outcomes from Task Groups is well established and successful. The resultant outputs will be reviewed via an open webinar for Credential Engines’ advisory group members and other stakeholders followed by a public comment period. This efficient process ensures orderly changes that support and expand the durable, persistent value of CTDL Linked Open Data. Once this process is completed, the CTDL family of standards and Handbook will be updated along with the Credential Registry publishing and consuming tools. The Registry and related tools and resources are freely available for publishing data to the Credential Registry.

Credential Engine is extending an invitation to you to join the CTDL Rubric Terms Proposal Webinar.
In collaboration with the CTDL team, the CTDL Rubrics Task Group (RTG) has crafted a proposal introducing CTDL rubric terms. Rubrics hold the key to unlocking a deeper comprehension of competencies within the context of credentials and job roles. By defining observable behaviors that indicate varying levels of proficiency, rubrics empower us to assess learning outcomes, gauge task performance, and more.
Already proficient in describing credentials, competencies, assessments, and tasks, CTDL is poised to take its capabilities to the next level by incorporating CTDL rubric terms. With the Task Group's work now complete, we are excited to present the CTDL Rubrics Term Proposal to stakeholders like you and eagerly await your invaluable feedback. At the heart of CTDL's evolution lies community engagement and feedback. This is your chance to delve into the RTG's efforts, review the proposal, and contribute your insights.
