Educational data is aggregated in various ways in EPASS, for example the number of validated assessments, checking of quantitative norms, an overview of the progress of the professional in all competency domains, but also overviews of narrative feedback that can be filtered on type and domain of feedback. These learning analytics contribute to the efficient use of an electronic portfolio system. Within the WATCHME project, several other learning analytics tools are added to EPASS. This project aims to improve workplace-based feedback and assessment and professional development by means of learning analytics. It solves the efficiency and quality problems of workplace-based feedback and assessment by means of an electronic portfolio system, that is enhanced with: a) student models that monitor the learners’ competency development, b) a Just-in-Time feedback module, c) visualisation tools that inform learners, teachers and institutes just in time as well as on an analytical level. Impact: Quality and efficiency of workplace-based feedback and assessment will increase, as well as the development of professional expertise throughout the domains.
