Re: multiple teachers in one dojo
Many dojos have multiple instructors (2-4), but there is always or should be a chief instructor that has absolute authority. Aikido is not a democracy. Anyways I have never seen two teachers have a disagreement (openly), but different teachers frequently teach certain techniques different ways and that can lead to confusion for the students. The chief instructor will usually know whether his assistants are teaching the students correctly by how well they perform during testing. Multiple teachers is a good thing though because each one brings something different to the table. Ultimately it is the students responsibility to stay on top of things.
