While an extended stay abroad is generally assumed to be a valuable experience, some students are reluctant to take up the opportunity. To understand this phenomenon better, this study looks at students' concerns before they embark on their time abroad (to undertake a study placement, work placement, or a language assistantship) and looks at returning students' perceptions, to see the extent to which their initial concerns materialised. The research is based on two questionnaires distributed to over 800 participants at two universities (one in the UK, one in Germany). Besides quantitative data, qualitative responses give additional insights into the students' perceptions. The results show marked differences between the two cohorts and also produce evidence of a considerable shift in students' perceptions after their return: a high percentage of students noted that their anticipated concerns were not realised. The results of this study are useful in shedding some light on students' concerns and can inform student support and Year Abroad (YA) preparation.
