Re: Underqualified Sensei
I have known a few schools that were run by people with little experience. It is probably getting harder to do with the internet background checking and lists of things to look out for when looking at schools. But, everyone has to be diligent in assessing schools.
Forming Study Groups under a qualified instructor is sometimes necessary and fine because they are not claiming to be an expert. They just happen to be the most experienced person in the study group and has regular instruction from a qualified Sensei.
