Just a couple thoughts:
1. Is there an "honors" option or some other accelerated class that she could go into?
2. Has your daughter talked to the teacher and asked to be pushed a little more or to have different assignments?
3. Have you talked to the teacher and expressed your desire to have your daughter pushed a bit?
It is very hard to teach a class with varying abilities and still be able to push the top end as well as hold the hands of those at the bottom end. My school has an Honors English at each level that students can self-select (it isn't tracked). But, within the context of the non-Honors class, I will work with a student to push them or to focus on specific things beyond what the generic assignment is if that student comes to me.
One thing I have been doing after focusing on feedback research this year is asking students what they want feedback about specifically rather than giving my general feedback (which I still do). I can go through the research if you want but that would likely bore you.
Some students will just dial it in if they aren't challenged. Especially since your teacher does not have past teachers in the district to give her an indication of what your daughter is capable of, you need to let the teacher know. I can't imagine a good teacher (and if you like this person, I imagine they are) not responding positively to your discussion.
Let me know if you have other questions/concerns from someone "in the trenches."
