Student-run hospital wards (SHW) are institutionalised learning arrangements in which nursing students are fully responsible for the planning, organisation, and implementation of patient care within a real-existing hospital ward for a limited time frame of usually two to four weeks during their initial nursing training. This contribution investigates a particular SHW using a theoretically-grounded research design employing research diaries, both pre-and post-test questionnaires, and interviews developed to get insights about why and how nursing students learn during their time in SHWs and what competences are developed.
