Well, I will reluctantly chime in here. I was a career educator, and my last job with education was as the Executive Director of Curriculum for a national education company.
What jlcnuke wrote in post #74 is perfectly correct, although I think he left some points out. Any curriculum designer who does not understand that should not have been hired in the first place. There is nothing wrong with having very high standards, but if you have very high standards, then your curriculum and instruction should be designed so that students can meet those high standards within the allotted time frame for the course. The one thing he left out is prerequisite skills--a course should have a screening process so that students who do not have the necessary skills and knowledge to begin the course do not begin a course they have no hope of passing. Students who have just finished Algebra I are not admitted into a calculus class for that reason.
In any course in any subject, if a student has the required entry requirements and then performs at his or her ability during the class, then failure should be rare. A class with a high failure rate is nothing to brag about. If a class frequently has a high failure rate and it is admitting appropriate students, it usually means the course design is poorly thought out, the allotted time for the curriculum is insufficient (you won't get a class through Calculus I in a month), or the instructional quality is poor.
I think it's a misunderstanding of what the course was designed to do. It's a screener for technical training, but it also functions as a workshop. Fact is, you can learn a ton from a class like that, but to pass at the technical level is going to take outside practice and work. It's simply not going to be learned within any reasonable course structure if you allow divers of all skill and experience levels to take the class. So you either limit it to more experienced divers, which introduces the problem of breaking bad habits and hurts newer divers, or you redefine what counts as a pass purely as a tech pass. But that doesn't work either, because it creates the impression that almost everyone fails. And if the goal is skill improvement, that doesn't paint an accurate picture of outcomes. So the only way I see that it's possible to both encourage new divers to take it and learn valuable skills as well as screen for higher level courses is to have stratified outcomes. Which is the system currently used.
