form of mobility that includes student, academic or administrative staff between separate institutions. It is based on academic cooperation and might be short term (e.g. summer, intensive or cultural exchange programmes) or long term (more than 3 months). Student exchange is carried out under an exchange programme or other agreement, usually established bilaterally. Types of exchange include physical, remote (e.g. virtual) and blended mobility. Students who move to the host institution are treated according to the conditions established by the respective programme or the corresponding agreement. Staff exchange includes teaching and/or training activities. The costs related to this kind of initiatives are determined by the exchange program or the institutions involved.
