My program is difficult, but I seldom have had anyone withdraw. People are there to learn and I'm there to help them. I donate my time and don't care if it takes them 200 hours of instruction for them to become certified (although over 90% complete the training in the time allotted). When they do, I feel confident that they could dive with any member of my family safely. That's my criteria for certification. Why would I certify anyone whom I felt was unsafe (regardless of certification level)? At this point, they are at the beginning of the journey and will learn much more as they gain experience. While they're learning, they don't present a hazard to themselves or their Buddy as they are competent to dive within the limitations of their certification. Usually however, they are eager for further training.
I'm not convinced that "making it difficult" equates to "making it better", which is the assumption underlying many comments like this. However, I certainly appreciate the attitude of commitment, dedication to good results and wanting the divers to get the best training possible.
I've read this entire thread up to now and I'd just like to add one thing, which is that in my opinion, if more instructors really committed to getting decent results as Wayne expresses in the bit I quoted then it would be entirely possible within current standards.
I don't like discussions about standards much because it never makes sense to me. Standards are just a check list of the minimal things you need to do. I'm sure (or I defer to your experience in any case) that standards are not what they used to be (the minimum has dropped) but they haven't changed much since I was certified nearly 30 years ago and the most important thing hasn't changed at all, which is that the instructor can make or break the course regardless of what standards say.
I think Lynne's example above is a good case in point. If her OW instructor had simply *followed* standards then she wouldn't have been certified because she wasn't able to master the descent, which is core skill. Her instructor violated standards, but the standard itself wasn't the big problem.
And that's the big issue I see with scuba training. There are too many lazy and/or incompetent instructors out there who are violating standards every single day, and THAT, in my humble opinion, is what is watering down the training. We can have all the standards in the world but unless it's policed and instructors are held to the bar of "mastery" before approving a skill, then nothing much will improve.
So instructors, take note. Look in a mirror and remind yourself of the definition of "mastery" before you approve any/all skills and you'll find that your results improve dramatically overnight. Because "demonstrating" something and "mastering" something are not the same!
