Yeah, but look at it from another point of view:
A restaurant's primary goal is to make money. If the kitchen doesn't have a broiler, you grill a steak on the flat top, if its cheaper to buy in fully portioned meats, then you do that. What I'm saying here is that the restaurant has no obligation to teach anything but the bare minimim, and many times the logic and theory is waaaay off(sear meats to lock in flavour, put hot liquids in the walk in to cool down, and other b.s.). There is no guarantee that what you learn on the job is right.
A qualification has to back itself up with test. Before testing, the correct technique and theories have to be taught and mastered.
Now, go back to the orginal post and read about the guy who can't saute a chicken breast, read about people's theories that sauting can take place with a lid on the pan, or that you can saute a whole chix brst on high heat in the pan with excellent results.
Does some sort of a culinary qualification make sense now?
