The Bachelor of Interdisciplinary Studies is an individualized major program. The program allows students to design their majors, in an interdisciplinary area that does not exist as a current degree at the university. A BIS degree program may include an existing UMSL minor or certificate program, and may include 6 hours of professional, service or research internship.

Interdisciplinary Studies students have designed individualized majors in areas as varied as art therapy, gender studies, gerontology, international studies, nonprofit administration and more. A student plans his or her own area of intellectual focus (Area of Study) with the help of the BIS Advisor and approval from the Interdisciplinary Studies Committee. Applications are reviewed whenever they are received throughout the calendar year, and students may begin the program in fall, winter or summer semesters.
