Yes. My point is that with some agencies even knowing how to swim isn't a requirement for training. It doesn't take a Rhodes scholar to realize that what you start with at the beginning of the process will affect the end result. It's panic waiting to happen.
Yes, I would agree that if you have to teach someone how to swim or be comfortable in the water then abbreviated class are not adequate. I guess that I just don't view teaching someone how to swim to be part of dive training. If someone came to my LDS wanting to learn to dive and they couldn't swim, the shop had the name of several swim coaches that they could refer them to prior to enrolling them in a class.
