I wouldn't want to be considered the "low end" of dive instruction either. I, for one, did not use that term. If I were to use that term, it would not be directed towards someone with whom I am not familiar. You have the ability to teach as good or as poor a class as you decide, regardless of your agency affiliation. If you are happy with your agency stay with it. If you are not happy with it, look around and make some changes. Additionally, I did not make any references to a scale of 1 - 10. I did not discuss the standards of agencies other than YMCA, NAUI or PADI because I do not have copies of standards from other agencies. SSI may be the best agency in existence or the worst, I have absolutely no information on it. I've heard rumors about various agencies, but rumors have no part in this discussion, IMHO, unless it is to attempt to verify or discredit said rumors. I do not believe there is a need for an open water class that takes six months to complete, nor am I aware of the existence of one. As for 10 year old divers, I've heard RUMORS that PADI and SSI have changed their standards to allow for limited certification of them. I have yet to see standards that reflect this. NAUI & YMCA have definately NOT followed suit nor are they likely to. If your agency allows for the certification of 10 year olds and this is a policy you disagree with; you are not required to teach children of that age. It's still your call.
Now, as to which agency is best, that is opinion, not fact. How one agency differs from another is factual. The relative value of those differences is opinion. Personally, I prefer a more comprehensive approach to dive instruction. I do not apologize for that belief, but you have every right to disagree. If I say YMCA is better than PADI, I am presenting an opinion as fact. Such a representation is wrong, in my opinion. If I say YMCA requires OW students to recover their mask and snorkel from the pool bottom and clear both the mask and snorkel; while neither NAUI or PADI require the same skill, that is a fact. If such a requirement is desirable is open for debate. I can ethically state that one program is better than another, in MY OPINION, but I should be ready to explain why.
