form of mobility whereby students and academic staff in higher education move to another institution inside or outside the country of their home institution to study, teach or carry out research for a limited time. Mobility can be broadly divided into structured (where institutions agree on activities during the mobility) and free initiative/self-initiated (when mobile participants go on mobility on their own initiative). There are several types of mobility and some of them, depending on the situation, might be attributed to both structured and self-initiated.
