Yes.
They are far apart in some areas, pretty close in others. PADI requires at least one skill that's never mentioned in NAUI's standards - no mask breathing.
I've yet to see where PADI's standards require the exam to be closed book. Where is that?
It's a joke, but at least it requires some swimming. PADI has a swimming option, but no swimming requirement.
Yes.
I've never found in the standards of either where it mentions open or closed book.
Actually, I believe you are mistaken. While it is up to the instructor to determine all requirements have been met, once a PADI instructor agrees that the student has met all requirements he has no option, he must certify the student according to PADI standards. Look in General Standards and Proceedures, you'll find in bold, "If you advertise a diver training course as a PADI course, you must conduct it following PADI training standards and issue a PADI certification to all divers who satisfactorily meet the performance requirements." Italics added.
Before or after NAUI revised their swimming requirements, that would be a violation of NAUI standards. On the other hand, that's been allowed under PADI standards since January 2000.
I do know the answer to the exam question. PADI does not permit open book or take home. NAUI allows either, but I would say that a take home test does not exhibit the same mastery of knowledge that a formal closed book test would. How do you really know that the student understands the information. There's a little risk management speaker in my head that says always side with the higher standard - cya - cover your ass.
As far as no mask breathing in NAUI, we do mask removal and replacement, so while the student has their mask off they're essentially 'no mask breathing' without it. And we could add in a time limit or blackout exercise or whatever if we felt necessary.
And for the swimming requirement, I dug out the manual for this one, 'Demonstrate novice level swim stroke proficiency in any of the following strokes: crawl, side, breast, elementary backstroke or backstroke....students shall complete at least 15 continuous stroke cycles...' So, my take is NAUI intructors can have their students swim as long as they need to be able to asses students have novice swimming skills. And that's what I do. Swim until I say stop.
Walter, I do agree with you regarding the standard if you advertise a padi course you must issue padi certification, but I do think there is a gray area here. Hold on, be patient with me while I explain myself here... All risk management says follow the standards (black and white) and use good judgement (very gray). What is good judgement. It's the hardest knowledge to impart on divers and instructors. There's always that term thrown around regarding skill assesment - "without undue stress" in place of the word 'comfortable' which can be vague. They have to be able to clear their mask "without undue stress", they have to be able to do alternate air sharing "without undue stress". So, I think you could catch yourself on the slate somewhere - noting 'diver not really comfortable' and that would be enough to hold back cert if you really wanted some solid evidence.
But morever, if I was having nightmare visions of runaway ascents and out of air situations from a diver that was exhibiting dangerous behaviour, I could not certify them. When making a decision (this may be quite morbit) I imagine that there's been a horrible accident, I'm in court and I have to defend my decisions and my actions. Imagine I said in front of a panel of experts, I feel in my best judgement that this person was not really qualified to dive but because they passed all the standards as I interpreted them I issued certification.....I'd be disciplined for sure, revoked, maybe worse.
