There have been times, when I was growing up as gifted but hearing...when I wondered if sometimes teachers were afraid of me. I had an English teacher in 7th grade that I'm pretty sure was, and my mom agrees that this teacher went out of her way to hold me back whenever she could. Our theory is that she rarely saw kids my age (and I was a year younger than everybody else) doing the kinds of things I did, and perhaps felt intimidated even though I would've never meant to do that to anybody. It also happened that I was having some personal difficulties at the time, and this teacher used that to try to get an edge over me.
So I wonder, do you think it's possible that teachers you know have acted like this, trying to intentionally hold you or your daughter back from the absolute furthest they could go to?
Oh, and congrats on having a kid so intelligent--and well-rounded! I'm pretty much strictly liberal arts myself...I love languages, and while I can do math if I MAKE myself do it, the truth is I just can't stand it.
