So all of the instructors in your system follow the same format?
I'm just curious of the dynamics of it, because at my school, every instructor has slightly different ideas of the best way to approach teaching. While we might teach the same material, some people think different things are important for each belt level. Some are looking at the full body movement during punches, some are looking at the stances during forms, and some are looking at other things.
So I'm just picturing the stance guy teaching his yellow belts the forms and paying attention to the stances, and then judging the other guy's test and seeing stances that are going to be cleaned up later. Or something like that.
This is what goes through my head, too. If I was still a member of the association I came up in, I could see some students passing tests with other instructors when I wouldn't pass them, and vice-versa - all because of some different emphasis.
There are standards set by the organisation.
So, the base curriculum (or format if you will) is set. If they want to go over and above that in some or all areas (with some or all students) that's hardly frowned upon.
If your instructor values more precision in stances, fine - but you still have to meet the standard for punching (and everything else) as well.
A stance can meet the required standard for 8th kup (say) and not meet the requirement for 2nd kup - but that doesn't mean an instructor isn't allowed to try to make all his 8th kup students have 2nd kup stances.
However, if those students have perfect stance but too sloppy body mechanics between stances, they probably won't pass.
Basically, you have to judge based on the standards set by the org, not by the standards set by yourself.
Hopefully, nobody has standards lower than the org minimum
Edit: that last statement isn't to imply that the org has low standards, but to be an instructor you should be able to have everyone you submit for testing meet them.
