Credential Engine is pleased to announce the release of new terms in the Credential Transparency Description Language (CTDL) to facilitate the publishing of Rubric information. This development is the result of collaboration with experts and partners in the Rubrics Task Group in accordance with our Significant Managed CTDL Specification Updates Process which ensures the enduring value of CTDL Linked Open Data. 

Rubrics are vital for understanding competencies in relation to credentials and jobs, outlining observable behaviors indicating a person’s competence level. These rubrics support various processes, such as assessing learning outcomes or job task performance. CTDL, which was already capable of describing credentials, competencies, assessments, and tasks, now includes rubrics. This addition enhances transparency regarding required competencies in specific contexts and their assessment methods. Moreover, the CTDL model for rubrics has broad applicability, extending beyond individuals and competences to appraise organizational capabilities and assess product quality or suitability.

At this time, the Credential Registry Publishing System is being updated to support publishing Rubric data to the Credential Registry, and an implementation webinar is scheduled for November 2023.
