Bachelor Students of International Studies (BASIS) is the study association for BA International Studies. BASIS was set up over the summer of 2012 by a group of prospective BA International Studies students, and has been steadily developing over the years. With around 600 members per year we are now one of the biggest study associations of Leiden University. Besides academic activities, we also aim to incorporate sports, music, arts, parties, and much more into our yearly planning. Discover what BASIS can offer you now!
