The Ateneo has international linkages with several universities, institutions, and organizations, particularly in Asia, Australasia, North and South America, and Europe. Through these cooperative efforts, the university hosts visiting faculty and research fellows from institutions abroad, and in turn, Ateneo faculty members also engage in teaching, research, and study in institutions abroad. International cooperation also includes active student exchange through Philippine immersion programs for a month or two for small groups of 15–18 students or full study programs wherein students from partner institutions abroad take regular courses.
