In education, we say that in traditional education, time is the standard and learning is the variable. In standards-based education, learning is the standard and time is the variable.
tldr;
performance based training. Wonderful idea. Saying yes to everything. Terrible idea.
Long version:
There are certain realities that I think you should take into consideration as an instructor that go beyond just looking at the standard.
The main one is the tension between time, money and learning. John put it perfectly by saying that in diving education, learning is the constant and time is the variable.
A lot of people who come into a diving course don't have this expectation, however, and where the rubber meets the road, you actually see a shift among many instructors/shops, BACK to a model where time is the constant (or nearly a constant) and learning is the variable.
Why does this happen?
I'll give you an example and walk through what happens.
What I tend to do within the limits I have at the shop where I'm on the staff (ie representing the business interests of the shop) is to make a frank appraisal after the first lesson as to whether or not the person is going to be able to learn what must be learned in the time we have been allocated. I don't only discuss this with the student but with the shop. Often times I will start trying to educate the student about performance based learning on day 1 and make them aware that in the time I have I can do only what they are capable of doing. As an instructor I put myself in the position of the intermediary to allow the student to talk to shop management about how much time they need and how much it's going to cost. I don't negotiate this myself on behalf of the shop. It's THEIR course and THEIR client. I'm just delivering it.
But ok. Say somone needs extra time. In some cases the shop will say "ok, give them an extra session" or "do some extra diving with them in OW" but the room to manoeuvre they have due to tight financial margins is limited. Likewise the student may say, "ok, i'll come for an extra lesson" or "ok, I'll pay for 2 extra dives in OW" but students are also limted in the room to manoeuvre in terms of the time they want to put into it and the amount of money they are prepared to pay.
So as an instructor, the theory that it's all perfomance based is wonderful and gives you a strong sense of direction in the process; however, this isn't public education. Real businesses are paying the instructor and real people are paying out of pocket for what they're getting. This leads to a reality in which many instructors are put in a position where BOTH the shop AND the student are telling them that they want the certification to take as little time and cost as little money as possible.
A great many instructors are not very good at managing this pressure and eventually start "reinterpreting" standards ... ie. looking for shortcuts or just ignoring what the standard says so they can make it fit in the time and budget available.
This is not so much that the
standard is changing, as the OP suggested, but the
delivery is changing to the point where it no longer conforms to the standard.
This problem is MASSIVE throughout the industry, from your home town dive shop to the big resorts. From the agency we are supposed to deliver performance based training but customers are normally on a fixed budget and timeframe.
It's not working.
let me say that again.
It's not working.
Results speak for themselves. Only instructors who are able to free themselves from the time and money problem are able to provide performance based learning as the agency designed it.
Ergo... getting back to where I started with this thread. If I see a student who I believe is going to have very significant problems following the course in something close to the time line I have available, I will advise them to seriously consider how badly they want to become a diver. I don't do this to discourage them, but to be realistic with them about expectations.
The shop hates me for this, but the only way as a shop instructor that I have any hope of delivering the required quality in the time I have available is to weed out students who clearly aren't going to make it as early in the process as I can.
That's not to say the student fails as in the case with the Rescue course, but to say... *I* as an instructor am not able to do what is required of me in this situation.
When your boss comes to you and asks you to do something in a time frame that you can't manage... what do you say? Yes?
Not me.
