Medical students need to become fluent in the native language of the country they will be working in before entering their work environment at the hospital. For this purpose, third-year students in the international track medicine (ITM) at Maastricht University attended the interactive online medical-Dutch language course. In this study, the aim is to provide more insight into the perceived value of the role of peer-feedback in achieving language proficiency and communication skills. Therefore, the study focused on peer-feedback and its value for development of communication skills and language proficiency. After the course, students completed a brief survey and participated in semi-structured individual interviews. The data were analyzed and main themes related to factors that influence the peer-feedback process were extracted. According to the results, students have perceived that peer-feedback is beneficial for medical communication skills training and language proficiency. Nevertheless, the presence of clearly defined goals and instructions (Rubric), native-peers, and guidance from teachers or facilitators are also crucial factors to consider.
