I may very well be speaking to myself, but nonetheless.
Mask clearing must be accomplished by the student or he can not be certified. Correct? Agency requirement, not up to instructor discretion.
This is a standard.
Completing skills competently, addresses the issue of performance. This is another required standard that must be met. One undefined by the training agency, which is left to instructor discretion and judgment. Correct? Nice way to shift liability.
I don't mean to intrude on your professional business, except for my concern that failure to hold training practioners to a defined minimum performance standard increases the risk of certifying divers who have not shown they can adequately handle a slight underwater incident. The lack of definition also makes it easier for instructors, who fail to exercise satisfactory judgment, to shift blame to the student, since there are no detailed codified rules that can be enquired of.
Much is made about the learners permit. But the certification also acts as a license to facilitate practice. To use drivers as an analogy. Agency standards dictate driver must demonstrate he can stay between the lines on the road delineating the lane. Problem is, where the lines are is up to a trained professional's personal judgment - or misjudgment. I'm sure glad driving standards are much more detailed and rigorous.
Raising the bar, if only slightly, should be to everyones benefit. Personally, this is a minimum amount of regards and respect owed students.
I'm being harshly critical, as I don't see anyone directly addressing these issues to assuage my, and no doubt, other's concerns.
Diving is performed in a non life sustaining environment for humans. This is not baking cookies, where if you burn them you can throw another batch in.
