In order to capture the experiences of students and trainees across Europe regarding the impact of COVID-19 on their mobility experience, the Erasmus Student Network (ESN) has written a research report on the topic. It builds on a survey in which 22,000 international students and trainees in Europe provided information about their experiences. The report aims to support policy-makers to make evidence-based decisions and alter communication in order to answer the major challenges students face during their exchange in foreign countries.
