Thank you, @DrTerriC, for your reply!
The way I've been brainstorming would be to create course templates for each iteration of candidate (4-year Union/non-Union, 2-year, etc.), then each year, create a "live tenure course", enroll the Provost as the Instructor, then perhaps the committee members as Observers, as I imagine the committee members would vary based on the department/college each candidate were applying under. Each part of the submission portfolio could be set up as distinct assignments that would be not graded, but marked as Complete or Incomplete. They could have their deadlines, and the instructions for each would be embedded in the assignment instructions.
Anyway, again, just getting started, but that's what I'm currently chewing on. I also considered doing it as a cross-listed course with a parent and a child/children courses, but I'm not sure that will work if they have distinctive assignments that don't mirror the parent course.
