I think most people accept this. After all, when you are talking about a large number of instructors, a large number of shops, and a lot of students, there's bound to be some issues with a certain percentage of them.
Maybe this is an oversimplification, but let's look at open water. If a student spent time on their knees beyond CW1, then their training sucked. I would argue that this is the majoirty of open water instructors across most WRSTC agencies. There are some exceptions like NASE and RAID that require skills to be performed neutrally buoyant and trimmed. However, instructors can still use the crutch and place students on their knees.
If in those open water courses the instructors didn't weight the students properly. I define "weight properly" as the minimal amount of weight required to maintain a safety stop with a nearly empty cylinder, empty BCD/wing, and if applicable a dry suit as empty as possible yet not sacrificing comfort and warmth, and be able to control the remaining ascent (to accomodate neoprene that may increase buoyancy). You never want to cork, even from 5 feet as you could still get run over by a boat.
Also in that definition, if the instructor didn't distribute the weight so the student can hover effortlessly horizontally, then their training sucked.
Now my limited observations doesn't necessarily translate to the entire world, but I would bet 7 figures that I am correct in that the vast majority (90%+) of open water courses fail one or both of these criteria.
I am sure others would disagree.
However, one of the pervasive attitudes on these boards - at least as it is expressed by a lot of the posters - is that there is a HUGE problem with NEARLY ALL of the training, especially when that training comes from PADI. Just look at what
@Forbin's Descent wrote in an earlier post in this thread: "Ha, me and thousands and thousands of other "certified" PADI divers. I will gladly send them their card back if they send me my $450 back. Of course, since these certifications are just made up things with no oversight, fraud is a stretch."
See above. For open water, I think 90%+ qualifies as nearly all. But we will never know what percentage meets/doesn't meet my criteria or anyone elses.
Now think about those instructors also teaching con ed. It doesn't present a pretty picture. When I see a platinum CD not being able to stay horizontal without finning, what kind of instructors do you think he churns out in Thailand?
There's a lot of ground between "There's nothing wrong with the certification process as it is" and "All certifications are bullcrap." I hardly ever see anyone take the former stance. I see a lot of people here take the latter, or very close to it.
I think most con ed is crap due to the lack of value. And I think that is where a lot of the derision stems from that you see here on SB and elsewhere on social media. I think con ed courses have the potential to be meaningful courses that result in an improvement in skills and knowledge. I see the requirements as being fairly pathetic. Real value is from agencies that allow instructors to augment their courses (only a few do) and where instructors take that opportunity to ensure there is real value (most don't).
I think for myself, if I were to do things over again, I'd have taken OW, then GUE fundies and keep working till I get a tech pass, then T1, and that's it. While GUE courses are expensive in terms of time and money, they have great value. 3 courses that would cover the diving that 95% of the diver population would ever do. T1 would replace the need for AOW. And if a dive center wouldn't accept T1 over AOW, would you really want to dive with such morons?
This doesn't mean that instructors cannot provide valuable courses who don't teach for GUE or similar. I don't teach for GUE and never will. But I do strive to provide value and constantly look for ways to increase that value. Fortunately, I am in an agency that allows this. Though I'd rather that agency raise their minimum standards.
I wouldn't say fraud is a stretch. As agencies know that they have crap instructors/dive centers and they look the other way for the revenue stream. Agency HQs really have to have their head up their αsses if they think everything is honky dory. So the fraud accusation isn't entirely unfair.
