Walter:Interesting. It seems you prefer instructors who keep class size down, yet somehow are able certify lots of students. How do they accomplish this? Perhaps with a c-card mill - crank 'em out as fast as possible, cut corners and get 'em through?
I suspect total number of students certified is not a very good criteria for choosing an instructor, unless it's used to weed out those with large numbers (when considering the time they've been teaching).
Hmmm. . . I re-read my post a couple of times and don't believe that is the position presented in my post. But thanks for pointing out that some may take it that way. I still stand behind the question, but, would add your point of evaluating the numbers certified over the time they have been teaching.
No matter whether it's YMCA, NAUI, PADI, CMAS, SSI etc. you will find C-card mills and instructors that will crank em out and cut corners. Bottomline for this post is students need to go beyond the certification agency and ask questions to find an Instructor that works for them.
