This unfortunately, is the case with many schools - little or nothing is available until 3rd grade. The problem is, our DC do not suddenly become quick learners in 3rd grade - so what do we do until then? Children like your daughter are gifted NOW and need an education that fits their needs before third grade. I share your frustration!
Others on this list should be a great resource for you - you can read about their various solutions to finding the right education for their young children.
We also have a school that doesn't formally identify until third grade. We waited to have my DD8 tested until this process took place at the school. Now I wonder if I should have done testing earlier. I also wonder in light of her test results how many "true peers" she has in the program, honestly. The experience with my DD is making me consider the possibility of having DS5 tested sooner. The only testing he has had so far was the WJ Ach. to get him into a summer program DD was in - the test results got my attention. The problem is, in some cases, even with test results, the school often will not actually do anything differently (YMMV).
The nice thing is, you already have the results in hand! I agree with PP - an IQ that high needs special accomodations. Your DD is significantly different from the average child, and even from the average gifted child. You will probably have to be flexible and ready to change course if the education is not keeping pace with your DD's needs.
I believe my DC's schools are well-intentioned, but I am not certain how much earlier test results actually would change anything for us. Although DS's school occasionally has him read a book at school, he is still being asked to count to 100 (he can add, subtract, and multiply) and did "letter sounds" with his K class - just like DD did in K (both DC could read chapter books before K). We do summer and after-school enrichment tailored to my DC's interests. Obviously, I am still (quietly) waging an uphill battle at school, but others here have had some success.
I think you will find many ideas and a great deal of support here - welcome!
