Professor Program ...
I'd have 3 levels ... Grand Master Professor, Master Professor & Professor.
Each level can only be attained by being the previous level for a set period (Prof to Master 6 months, Master to Grand 1 year) & passing the exam with a higher pass mark required. The exam would be 100 questions & each pass level would be Prof 70%, Master 80% & Grand Master 90%.
Fail a level when trying to move up & you stay the your current level & can only try again after a stand down period (Prof 2 months, Master 4 months & Grand 8 months). Retesting would be every year on the aniversary of the level you are on. Fail to pass the requirements for your current level & you drop down to the next level, with the same conditions as the stand down periods (this is different to Magic which has no retesting).
I'm currently a Master prof & might fail to keep that status under this system, but this would create respect for the Professor Program (I'd be proud to make & retain any level). It would lead into rewards like ONLY Professors staffing / judging the Major events (Worlds being the obvious ... starting with PUI staff then Grand Master Profs, Master Profs & finally Profs until it's fully staffed).
Grand Masters could be included as part of the Rules Team & be consulted (via email if required) in any meetings of the team. Players would respect any rulings as they would know what it takes to become a professor of any level.
