Thanks for all the input. The reason I asked was that we recently had a guest instructor from another dojo in our style and he said that he wants his students to show the initiative to come up and ask. This sounded a little different than most everything I'd heard about other dojo, so I was just curious. I guess it really comes down to "his dojo, his rules".
I guess as the starter of the thread it's only fair that I contribute.
We have kyu testing every 4 months. There are minimum hour reqs. and you must have instructor approval. There's the rub. Every time testing comes around the dojo-cho tallies everyones hours and hands the list of eligible people to sensei. He goes down it and decides who to place on the testing list. He doesn't really like the asking thing all that much I don't think. He did say that if you know you have way over the required hours and you don't end up on the list it's ok to ask what you need to work on to be considered (it may also be a book keeping error
Again, thanks for the input
