Undergraduate student mobility in Europe, which is seen as a desirable objective by the European communities, is examined in this study. The idea of mobility includes a term or year of study in a foreign country as well as stays of a month or two resulting from inter-university agreements or twinning schemes, or even periods of training that round off the requirements for certain diplomas. This report deals with: the motivations underlying undergraduate student exchange; the less-than-satisfactory level of student exchange; obstacles to the free circulation of students; and organized mobility. A pragmatic policy is proposed, including the development of a practical guide for students containing information on admission requirements; a summary of the university systems; courses, grades, and diplomas; cases of equivalence; scholarships; and advisory agencies. Included are draft proposals for: establishment of a consultative committee; improvement of relevant statistical information; the level of British enrollment fees for other EEC students; equality of access to higher education for the children of migrant workers; and time allowances for periods spent abroad for purposes of study.
