Pretty much what you said, you aren't allowed to weight students before you put them underwater on SCUBA. That pretty much eliminates doing anything on SCUBA correctly during CW 1.
Not at all.
In CW2, you are evaluating the student's ability to do a buoyancy check. That doesn't preclude you from getting the student diver correctly weighted by talking them through how to do a buoyancy check and evaluating the amount of weight they need prior to that.
There is, even with in PADI instructors, a real lack of understanding of what you can and can't do. It's not surprising that non-PADI instructors don't understand it either.
Why in the world is that? If I became an instructor I would want to set a minimum level of skill that I would want every one of my students to complete to earn my certification. How is it that an agency can force you to lower your standards?
The intent of this is quite simple. These are the skills that PADI believe are required to be a capable open water diver. The student must be able to do those skills to level of performance specified in the standards. That doesn't mean that you can't add additional skills - but it does mean that you can't mess with the objective standards. For example, the performance requirement for the hover is confined water is (paraphrased) "hover motionless without kicking and sculling for 30 seconds". You can get your students to hover for five minutes if you like, but any student who can hover for 30s is deemed to have performed the skill. You can't "fail" a student because they don't hover for five minutes.
It is intended to maintain consistency (though some would say at a low level) across many instructors. I'm being picky in terms of language, but if you really think that you would teach such that "every one of my students to complete to earn
my certification" then PADI is not the right agency for you. It is a PADI course, not a bjjman course.
That's not to say that PADI courses are inflexible, far from it.
That is correct, good PADI Instructors all have to become masters of "elaboration," the PADI term for those things that may be added, but not tested.
Correct, that results in what PADI Instructors denigrate as, "know-it-all" classes.
I agree with your first comment, Thal. To teach effectively in the PADI system you need to be aware about what you are allowed and expected to do. But it's not rocket science to do that.
Your second comment, however, is a gross generalisation and makes it sound like all PADI instructors have issues with NAUI courses. That's simply not the case.
