Thanks, Stacychev. I really do see the word around and it seems like it is some sort of polymorphic euphemism. In that a bunch of people (non-professionals thinking now) agree that more rigor is needed and yay they go home happy. But then, person A actually means a minimum of two hours of homework a night as rigor, and person B means that everything that might be on end of year testing is covered twelve times, and person C actually means things are taught exactly they were when they were a kid, and finall person D means intellectual rigor and complexity of thought. I'm relieved that in the "biz" D is what is meant.
I hope you find the situation that works for your daughter.
