Reminds me of the way Japanese martisl arts masters and Zen masters sanction their students to teach. This (theoretically) results in unbroken lineages that ensure that all "Masters" skills have been verified in certain ways. I dream of a similar system being used in other expert subjects. A mentor/mentee work together for a long time until the mentee gets the blessing. It would be good for things like rollercoaster building, where an exam may be too difficult to design to cover all levels of understanding required,and the knowledge is held by a few "old timers."
