ISDSI works with a large number of schools, on both short term and semester programs. We have have had over 500 students from over 30 schools and 40+ different majors.
ISDSI does no paid advertising, and sends out announcements through our own email list of faculty and friends. Most of our growth has come by word of mouth by students and faculty. We limit enrollment to approximately 30 students a semester, generally with higher enrollment in the fall semester and smaller enrollment in the spring semester. Short courses are generally by request from colleges and universities in the United States, as well as other programs (such as gap-year programs) on occasion.
