The underlying goal of Goethe-University is to be perceived as an international university. Thus the internationalization of programmes of study, research, teaching and administration has become a high priority and lead to the development of an official concept for the internationalization of Goethe University. It lists measures such as intensifying and selective extension of cooperations to increase the mobility numbers of students and teaching and administrative university staff members, the increase of English-taught courses and degree programs, and an as much as possible bilingual administration. The implementation of student, teaching and administrative staff mobility within the ERASMUS+ Program enables us to reach our strategic goals in the medium and long term and to use synergy effects in the cooperation with our partner institutions. In the academic year 2014/15 a total of 449 students of ours studied at one of our partner universities for an average of 5 months, continuing the trend for one semester stays. The sponsorship of study abroad periods within the three study cycles aims at the improvement of language skills, promotes intercultural competence and allows an insight into different study methods. In addition within the framework of our membership in the consortium for EU-internships we are able to sponsor internships of students and recent alumni, who get an insight into foreign work structures and improve career entry chances. In 2014/15 we counted twenty-six teaching staff mobilities with a duration of approximately 8 days on average. These provide the chance for knowledge transfer and internationalization of teaching, research and campus and promote the exchange of teaching methods, the establishment of new networks and the intensification of existing cooperations. Four of our administrative staff members used the chance for advanced vocational training and professional development within a staff mobility exchange, two of these at our strategic partner universities in Prague and Birmingham. These mobilities support multilingualism and intercultural competence of administrative staff, which is required in many fields of counseling and advising international students and teaching staff. In addition Goethe-University and our partners profit from the exchange of best-practice methods by optimizing administrative practices.
