The last 5 years TEI of Athens has developed a prog ram of Functional Evaluation of student Mobility with the help of questionnaires . Three quarters of the responders were male; most of them participated in the Erasmus program for studies and one third of them for placements. From the statistical elaboration of the answered questionnaires, the most important issues that came to light were the language preparation and the information/support in matters of accommodation as well as the functionality of the ECTS system. Howev er, a great percentage of the responders feel “satisfied” with the recognition of the courses and half of them associate their participation to the program with t he extension of their studies’ period. Finding a solution to the aforementioned is sues demands of combined actions undertaken by the National Authorities and Agencies, the Higher Education Institutions and the relevant Departments, but the financial support of those actions remains always the “dark side” of this matter.
