This dimension (of digital assessment) intends to make the entire competence assessment program visible and comprehensible for all participants. For this reason, it is important that the students/learners are able to understand the fairness of their assessment, as precisely as their instructors, requiring them to have a complete knowledge of all assessment criteria and their relative weights. For this dimension four criteria were considered: democratisation, engagement, visibility and impact. (Tinoca 2014, p 22)
