Credential Engine is clarifying the diverse marketplace of certificates by providing more extensive credential type definitions, in order to help people make informed decisions. We need your expertise and feedback to confirm the proposed additions to the Credential Transparency Description Language (CTDL). 

The CTDL Certificates Task Group, which included experts from education, government, licensing, certification, training and other arenas, worked in collaboration with the Credential Engine CTDL team to introduce new certificate types, definitions, and usage guidance as part of the CTDL. Certificates play a pivotal role in learn and work ecosystems, and this proposal seeks to enhance the definition of certificates for greater clarity and transparency.

This proposal complements the existing capability to describe a wide range of credentials, learning opportunities, competencies, assessments, jobs, pathways, and more. The CTDL Certificates Terms Proposal takes this a step further by refining the granularity of valuable certificate data. 

You can provide feedback by reviewing the CTDL Certificates Proposal and adding your comments or by reviewing the proposal and emailing  You can also learn more and engage with the Credential Engine team in our webinar on this topic.
