I3D Header Graphic - DUS


The Interdisciplinary Studies in Three Departments (IS3D) major at San Diego State University is a special major designed for students whose career goal or academic interest is not addressed by an existing SDSU major or major/minor pattern. Because three disciplines are involved, the program must have a clear focus and depth that make academic sense; the areas of study and the choice of courses within these departments must complement each other. Students are responsible for identifying the field they wish to pursue and must be able to defend their choice orally and in writing.

All students interested in the IS3D major should view the 17 minute informational podcast about the major and create an initial draft of a master plan BEFORE visiting the IS3D office for walk-in advising. Links to the podcast are below.
