...All of the main-player agencies instructors have been teaching from the knees for decades. NAUI also has plenty of kneeling photos. CMAS/FFESSM teaches from the knees also IME. SSI the same. PADI seems to be the first to announce a substantial change in 'the way the world learns to dive'. I expect the other equivalent agencies (SSI, NAUI) to follow suit....again.
I think that we can look at this through different perspectives:
1. What does the Agency stipulate? ... A discussion about Agencies
2. How do Instructors teach? ... A discussion about Instructors
If the discussion is about Agencies, in all fairness I see a difference between:
1. PADI: In CW1 this is what you teach and the Instructor must not deviate from the program (content); and
2. NAUI, CMAS (and other Agencies): These are the "Minimum Requirements" for certification; but the Instructor should add whatever knowledge and skill-sets that the Instructor feels required as a condition of certification.
PADI specifically quantifies and restricts what can be taught in an OW program and specifies when it is to be taught. This certainly puts the Agency in control of what the PADI OW course looks like. It is designed to be the same program anywhere on the planet. Other Agencies
specifically do not make such a requirement.
As you have mentioned NAUI and CMAS, neither of these organization (at no time) in their Standards mentions "the bottom" at all, or makes
any suggestion in
any instructional materials that
any skill must be undertaken on or near the bottom.
Like you, I've seen photos showing kneeling. I interpret this as how one particular Instructor chooses to teach (opposed to what the Agency requires to be taught). Again the when and how is not an element for most Agencies.
It's worth mentioning that Agencies do make a requirement for certification which states (quoting from the NAUI Instructor's Manual): "Environmental Skills - Dive using skills that have a minimal impact on the environment and promote conservation."
A similar statement is made in Section 7 of the CMAS requirements for certification. So it would be a breach of NAUI and CMAS Standards to do otherwise in OW. The Student's can't be on their knees in OW. So the Instructor has no other reasonable option than to teach them in neutral buoyancy.
I don't understand why anyone would suggest that if PADI made changes the other Agencies would follow suit??? There are NO CHANGES that are required (in NAUI and CMAS at least). It's left up to the Instructor how s/he wishes to fulfill his/her training program and meet or exceed the "Minimum Requirements" for certification. This has
always been the case.
PADI placed all sorts of restrictions on their Instructors in the early 90's. They moved into a teach-by-numbers approach. It would seem that they felt it the best way to manage a huge number of Instructors and develop their brand. No doubt they've been successful. This necessitated the development of a "this is what you teach and when formula."
No other Agency (that I'm aware of) operates in this manner. If PADI makes changes, it will only affect PADI. Many (if not all) the other Agencies have left it up to their Instructors to decide how they will instruct their students to meet the minimum requirements.
I've been teaching "off-the-knees" since the early 70's. Should we elect to do so, myself and tens of thousands of other Instructors are insured to teach in this manner. How they elect to teach, is another matter completely...
