Allied Fields Two of the six courses in the Graduate Certificate must be in an "allied field," another discipline relevant to technical communication. These must be graduate courses taken in the last five years, and must be approved by the Director of Business and Technical Writing. Usually, the two courses are taken in the same discipline, although exceptions can be made. In some instances, students who wish to use the linguistics course in fulfilment of their language requirement may opt to use linguistics as their allied field, or linguistics may serve as one of the electives. The most important factor is that the courses expand and broaden the student's education in technical communication. M.A. students in English pursuing this certificate may choose to do a master's thesis in technical communication instead of the two allied field courses. Allied field courses have been approved in fields such as Linguistics, Management, Marketing, Psychology, Education, and Engineering Management.
