You say she's not part of the instructor's family. Does she work in an official capacity at the school or is she just another student who happens to be a black belt? If she doesn't work there I don't see how she is supposed to be role model. Either way, it is a teachable moment for your kids.

She does not work there for money. She does assist with classes and is in the process of becoming an instructor. Black belts are held to a higher standard and are to be role models. That is what the lower ranks are trying to model and achieve.
