This rubrics and glossary can be used to assess competence and proficiency in the skills identified in the Profile of the Data Practioner. The rubrics provide examples of what the work responsibilities of a Data Practitioner (middle-skilled data worker) “look like” when performed at four different levels of proficiency. They are built from simple, contextualized examples of a Data Practitioner’s work activities, then scaffolded to illustrate increasing skill mastery. The rubric tables can be used as a framework for faculty, students, and employers to assess the extent to which data worker skills have been mastered.
