Teaching higher grades than your own

[pers]

Hi Guys,

A friend of mine runs a Karate club but he's 1st Kyu, he's had a few 1st dan/2nd dan friends of his approach him for lessons and I'm wondering, have you ever experienced this? if so, what did you do?

I have a different opinion on this, giving training and teaching are two different things, normally a higher grade should know more or as much as the guy running the class, unless the instructor is a cut above and undisputed master of the art.

There is no harm and nothing wrong to train in a class where the instructor is lower rank than you but an able sensei, you would definitely get a good workout and maybe pick up few points and tips that you may have forgotten or never came across.
