The general aim of the guidelines is to ease current barriers to mobility and to increase the participation of underrepresented student groups in physical credit mobility at European higher education institutions. The guidelines will allow International Relations Officers (IROs) and Higher Education Institutions (HEIs) to better understand the differences in the student population at local level and the characteristics of the currently underrepresented student groups in international student mobility. The “Social Inclusion and Engagement in Mobility” (SIEM) project aimed to make the Erasmus+ programme more inclusive and to increase the interaction between international students and local communities.
