I have a young 1st grader and she's in a very high performing district. I'm not sure if you still need the info but I'd say that she seems to be fitting in just fine and can read kids books (more than Dick and Jane but not chapter books) she's much more of a math kid, though. Spelling tests at the beginning of the school year are 3-4 letter words. They do short stories sometimes in terms of writing.

From what you've described I'd guess your kid would be pretty bored with the reading assignments/spelling tests. Where is she in math? That could also be a deciding factor.
