Why study Interdisciplinary Studies online through OSU?

The online Master of Science in Interdisciplinary Studies is for students who wish to increase their competence in a particular thematic area by taking a series of courses in several disciplines. This multidisciplinary approach provides educational opportunities leading to a variety of careers. The Master of Science in Interdisciplinary Studies requires a minimum of two separate fields of study. The advisory committee will assist the student in formulating the Plan of Study.


Courses are delivered through Canvas, OSU’s online learning platform. Courses are taught asynchronously so students can fit them into their schedules.  From lectures to discussions to submitting assignments, all course interaction can be completed entirely online.



Students work with the Graduate College advisor and the advisory committee to specify the courses. The course of study must include at least 21 credit hours at the graduate level (5000 or above). Up to nine graduate hours can be transferred from a regionally-accredited graduate program with consent of the advisory committee. The student chooses one of the following master's degree plans:


  1. a 30 hour plan, including a six-hour research thesis;
  2. a 32-hour plan, which may include no more than three hours of research with a grade of "SR." May include a culminating experience (e.g., final report, internship, practicum, comprehensive exam, and portfolio or capstone project).


An undergraduate grade-point average of 3.00 is required for unqualified admission. Students with a grade-point average between 2.50 and 3.00 may be admitted on a probationary basis.

To apply for the program: 

  • Include a cover letter indicating the personal goals and professional objectives to be obtained from the program
  • transcripts from all schools previously attended
  • three letters of recommendation from persons who can describe abilities, interest, and motivation as a student
  • a proposed course of study with an endorsement from an OSU faculty adviser.



Students enrolled in the Interdisciplinary Studies (thesis option) master's program will complete 30 credit hours during the course of their studies.
