A routine look at divers in pretty much any resort destination in the world will show you a fairly high percentage of divers who scull with their hands, bicycle kick in a vertical orientation, kick or bounce off the bottom, and way too often end up having to share air with the dive guide. These are not what I would call good, safe, or comfortable divers. And yet I'm certain that the person who taught them how to dive will claim that they taught the class according to standards. Perhaps they did ... but how well did the student retain what they supposedly learned?
Yes, Bob, it is definitely true that a student can be taught to the standards of probably most agencies, including PADI, and be that unskilled. No question about it.
When our group was getting our article about teaching buoyancy in OW classes published in the PADI professional journal, I had a very long discussion (argument) with PADI leaders about this very topic. I focused one part of that discussion on the specific example of an OW class I observed in which this very thing happened--students spent almost no time learning other than on their knees, and they displayed no competence whatsoever in the rare moments they were allowed to swim. Yet the class was 100% within standards.
Since that discussion, several others in our group, especially Peter, and I have had continued discussion with PADI on these topics.
This year PADI has announced to its members that it will be making significant revisions to its OW standards in the coming year. It will add significant requirements in all the areas of concern, including especially buoyancy, trim, and gas management. We have not seen those changes yet, but this is welcome news. As instructors, we could always add that information to our courses before, and many of us did, but many of us did not. Now it will be required.
Were our efforts instrumental in making these changes? I cannot say for sure about all of them, but I do know that some of them came from us. I was told in clear terms that some changes, including a suggestion from Peter, would be implemented as a direct result of our prodding. If not, though, who cares? I look forward to these revisions regardless of their inspiration.
