Don't forget we're talking about training
users here, not biomeds.

And on the "dumbing down" issue ... any course that I was in charge of have would
always have a few failures. Why? Just to encourage the rest!
That is, if high standards aren't set ... what value is the training? In fact, why bother at all?
Sorry if people get fed up with me mentioning the army (heck, why should I apologise?) ... but on some courses,
no-one passed. And there were many courses where only one or two (out of many who started out) passed muster. I remember a case where two guys were booted off in the last month of an 18-month course (that certainly made the rest of us buck up a bit)! Standards were never dropped just because the raw material was lacking in some regard. That's what maintaining high standards is all about! How's
that for a Quality System?
Of course, that sort of thing flies in the face of official policy in our wonderful Nanny State; where no-one fails, and even the dumbest of the dumb, and the obviously ill-suited, can strive on to several levels of magnitude beyond their natural competence.
Pathetic is the word that comes to mind!
