Jeff understands it completely. Had I been able to at the time, and saw that the YMCA profgram was going to close, I'd have found some way to come up with the extra funds to take the NAUI Instructor route as opposed to the YMCA. The morals and ethics of the programs were nearly identical. As were the standards that mattered to my style of teaching. But at the time the YMCA Instructor exam was under a grand. The NAUI route was $1800 by the time all was said and done. And I hold a couple NAUI Tech certs that I got before moving to instructor.
Not being psychic I saved some money. And in the end it all worked out anyway. I got in on the ground floor with SEI and, like NAUI, instructor input is valued, solicited, respected, and implemented. I've authored two courses, was co editor and author of another, and helped establish the standards for our Advanced Level Classes (formerly AOW) by requiring divers who have not had the rescue skills Jeff noted, as well as panicked diver, taught in their OW class to be remediated and covered. Either as an addition to the Advanced Level classes or as a workshop type course before they can begin the Advanced Level training.
My feeling is that you do not give a diver access to dives where things can go wrong faster for them and their buddy with potentially more serious consequences without giving them the knowledge and skills to assist each other. Just as I would not allow anyone I cared about to dive with a person who does not have those skills at any level.
