8.80.12 A temporary course may be offered no more than twice and only during a two-year period following its approval. A temporary course must meet one or more of the following criteria: a) it is experimental in nature. It is innovative, using unconventional devices or pedagogical methods, course materials, approach to course content or student-teacher relationships; b) it is being tried out on a temporary basis so that its value and effectiveness can be tested before it is added to a department's permanent curriculum; c) it is intended for a limited duration, such as in the case of employing a visiting specialist temporarily available or to satisfy temporary needs and interests of students or to deal with timely issues.
