Mark - you are definitely on the right track - as I've commented before, not only are our WWII brothers dying off, we are also losing DBFers from post-WWII at an alarming rate. PAMPANITO has been working to recruit nuke submariners as well as truly interested civilians to start coming into the docent pipeline. If we don't, we'll be out of qualified docents in a few more years. Thus, setting up some form of docent exam accomplishes many positive things -- plus, it helps some of our DBFers keep the facts straight as well.
PAMPANITO doesn't have an exam per-se at this point, but we are developing a series of detailed, illustrated manuals for such evolutions as reballasting the boat, starting an engine, raising a scope, as well as several others. Plus we have an extensive docent manual that gives PAMPANITO's history from construction thru becoming a museum boat and provides lots of detailed info on most of the systems.
What we really lack at this point is much detail to answer "what was it like" questions. Our audio tour (iPod based) uses actual WWII crewmembers to narrate each compartment that adds a lot of "color" to the tour because to some extent, they describe conditions on a war patrol. This audio tour is available at our website if you want to give it a listen.
