The M.A. and Ph.D. programs require coursework outside the department, either as a formal minor or “supporting program.” These courses (at least 6 credits for the M.A. and 12 credits for the Ph.D.) are intended to complement your R&STC program. You need an outside member on your exams; if you have a formal minor, that person must be on its faculty.
The current Graduate School Catalog describes minors in many departments (in each department’s “Degree Program” section), as well as several free-standing interdepartmental or intercollegiate minor programs.
Minors popular with students in Writing Studies include
Other departments – not all have both Masters and Doctoral level minors
Other free-standing minors
Unlike minors, a supporting program does not have to meet the formal requirements of another department. A set of complementary courses from one or more departments—but not Department of Writing Studies courses, and approved by your advisor—constitutes a supporting program.
