You say she was evaluated at DRA 9-10, and their books go from 3-10... looks to me like they evaluated her to the highest level they keep in the class, and then stopped.
At this point, I'd say you've accomplished all that polite asking is going to accomplish, and it's time to start becoming "that parent." If you have the opportunity to demand screening and an IEP, take it.
Also, I see from another thread that you were offered and declined a grade skip (assuming we're still talking about the same kid). Honestly, I don't see it helping here, because she's far above the 1st grade curriculum as well, but it might be worth revisiting.
It's also worth considering how an IEP would translate into effective accommodations. I know in my DD7's case, the school's plan was haphazard and damaging in many ways, and your DD is further off the charts than mine. We were left with no choice but to homeschool.
