I think Game Management Skills increase with wisdom.

While most anyone can be taught to remember rules, situation control and the like, every facet of communication (verbal, non-verbal) has a large impact on how your game management skills are perceived by others.

In short, an "Exceptional Official" will be one [everything else being equal] who has a thorough understanding of communications skills and has extensive practice in their execution.
A "Good Official" will be one [everything else being equal] that has effective communication skills but has limited experience executing those.
