On this very rare occasion I'm going to have to disagree with you Crowley.
There are a lot of standards, yes, hence why we have the manual and all instructors (and future DM's) are required to have it. There is no excuse for not knowing a standard.
And we should all make the effort to refresh our memories on a regular basis. I always run through core courses when a new manual comes out so as to check that nothing mega has happened e.g removing the fin pivot.
Although it does amaze me how people can fail the standards exams in the I.E
It's open book ferrchrissakes!!!!!!!
No worries mate, it would be a dull life if we all agreed and if we did, Scubaboard would probably have gone offline about a week after it started!
We could test each other on standards knowledge and I bet we could all dig out a few surprises here and there as in the "ooh I didn't know that" etc. but I think it's okay to not remember everything, although I would take issue with somebody not reviewing standards prior to teaching an unfamiliar course.
Part of the reason I sympathise with the OP is that I wasn't certain of the depth standard for juniors when it came to teach my first junior diver - which was actually a few years into my career. I had to review them prior to teaching, along with all the junior diving paperwork, and yes, I found myself thinking : "I'm sure I was told it was 12m for all juniors..."
I don't think this means you can't trust an instructor who cannot immediately come up with a standard with which they are not familiar. I doubt there are many instructors who could recite, verbatim, every standard in their agency handbook.
I generally don't teach kids, it's as rare for me as teaching DPV spec., of which I have taught two in 6 years, and nope, sorry, I can't remember all of the DPV spec. standards.
What I DO know, on the other hand, are all the standard safety standards, and therefore what I need to review is the standards specific to that course. Just like a junior diver - the depth restriction I know, but I can't repeat every standard pertaining to juniors off the top of my head and would have to refer to the manual - and I doubt anybody could give me the entire DPV outline without having to look it up a bit.
In terms of the depth restrictions, if an instructor mis-interprets "junior" as "limited to 12m" then yes, this is incorrect, but if something goes wrong underwater is a lawyer really going to say in court: "you are a bad instructor. you violated standards. you restricted a junior diver to a depth lesser than to which their certification entitled them to dive. that is why the accident happened. you are bad."? If that's an honest mistake, so be it.
I think that, overall - in terms of the amount of other standards that we have to abide by when teaching diving in general - not knowing this particular standard is forgiveable, on the assumption that all other standards were adhered to, and that "not knowing" a standard does not imply that the error was not subsequently discovered whilst the instructor was reviewing course standards prior to teaching something a bit different.
Would somebody please pass the popcorn?
Safe diving all - but please, not too shallow, okay!?
