here are various reasons that study abroad has become increasingly more popular and prominent, some of them can be associated with the human capital. For instance, studying abroad can directly or indirectly influence students’ career paths and potentially offers additional job opportunities. In Europe, a very important opportunity for study abroad is well known Erasmus student mobility programme. In the paper we defined a network of Erasmus student exchanges on the institutional level. Firstly, more important universities with the highest number of Erasmus student exchanges were identified. Majority of them are coming from four the most represented countries in the programme: Spain, Italy, France and Germany. With the help of an advanced network analytic method – the island approach – we were actually able to determine the groups of institutions in the network which collaborate most extensively inside of Erasmus student exchange programme. Moreover, important islands were identified and analysed. We also confirmed findings of other authors on the same topic although our research was conducted over longer period of time.
