You mean like the rstc? Oh that would be just great. Look at the job they have done to keep standards high and insure quality training. Right. A central agency made up of the various agencies now. Whose standards do you model it on? The highest or the lowest. LA county program standards, YMCA standards(they were the first national cert agency), or one of the newer ones that allows someone to be certed in a weekend? No what is needed is an honest comparison of agency standards in an easily accessible place so that potential students can compare them and choose the one that suits them best. Along with reviews of each program by random grads of the ow programs.
The issue you address is just what I am responding to, a total lack of any real training program. Currently we have a cottage industry, each making their own rules and programs. We have almost anyone certifying almost anyone to dive, it is a complete mess. As this outfit amply demonstrates just what is wrong with our current path.
What we need is to set the standards high enough to insure safe, trained competent divers, and make it affordable. It must also be done in a reasonable amount of time. It will not be like RSTC that goes to the lowest common denominator, but rather we need to set the bar up to a higher standard. Some go way over the top in so far as training is concerned, and others are less than competent.
A comparison of agencies would be nice, but will never be a reality. Trademarks and copyright infringements and other business practices will make this impossible. With this reality in front of us, the only real approach is a single certification agency, with the ability to hold instructors accountable and have the ability to withhold compensation. The only real way to keep the program standards real is to penalize those who do not instruct the students iaw the established standards.
