The Inter-D Program (Interdisciplinary Studies) graduate program at USask allows students to design their own graduate program with oversight by the CGPS' Interdisciplinary team to bring together qualified faculty from different disciplines. Because there are no constraints on which fields are brought together, there are virtually no two students in the same subfield.

Interdisciplinarity suggests establishing connections across, or the hybridization of techniques, tools, or theories from, different disciplines in order to advance understanding beyond the scope of a single discipline. It can also suggest creating “undisciplined” spaces between disciplines or working to transcend disciplinary boundaries altogether. Interdisciplinary approaches take on issues, problems, or creative projects that cannot be adequately addressed within a single discipline, or even multi-disciplines.

To be considered "interdisciplinary" individual programs will integrate course work and research that crosses two or more disciplines into a concise program that is not available within the traditional academic setting. InterD students create their individualized program of studies with their supervisor and Student Advisory Committee.
