Different types of media such as video, audio, or images are increasingly used for the assessment of students’ competences. However, as they allow for a large variation in performance between students, the process of grading is rather difficult. The online tool D-PAC aims to support educators in the assessment of video and images. In D-PAC, students can easily upload their work in any media type (text, audio, image, video), after which the work is presented in randomly selected pairs to the assessors. The only task for assessors is to choose which one of the two is best, using their own expertise. Assessors find it easy to make such comparative judgements because they are not forced to score each work on a (long) list of criteria. Each work is presented multiple times to multiple assessors, resulting in a scale in which students’ worked is ranked according to its quality.
‘Working with D-PAC was really easy and fast.’

Recently, D-PAC has been used in a Bachelor Multimedia and Communication Technology for the assessment of students’ animation skills. Students received an audio fragment of the radio play by ‘Het Geluidshuis’ and had to accompany it with animation. A group of 9 assessors evaluated the quality of the animations. The assessors differed in background and expertise: 3 people from Het Geluidshuis, 2 expert animators, 2 alumni students, and 2 teachers.
