Hey shippy, seems a shame nobody’s replied to this, but here’s the status (as of 2015 at NPTU Ballston Spa, S8G prototype):
The position is now called EOOW Training Assistant, almost always spoken ETA and is usually filled in each section by a CPO. The position mostly handles scheduling and manning final watch boards and oral boards for JOs. It is not nearly as well defined a position as Training Coordinator or Leading Crew Chief these days, it seems the program has shifted more toward the KAPL civilians handling most of the EOOW qualification admin. As a side note, E-6 and E-7s qualifying EOOW is relatively commonplace these days, there were always at least 4 or 5 E-6s qualified plant wide during my time. Hope this answers your question.
