Research Fellow Joost van Kordelaar (FMG, former FNWI) researched rubrics as an assessment tool within the theme of (Formative) assessment and feedback. The psychometric properties of rubrics and assessor satisfaction formed the core of his project. He developed a dashboard that allows assessors to analyze psychometric properties, such as validity and reliability, of their rubrics. In addition, he examined assessor satisfaction of rubrics with a questionnaire survey.
