I try never to base placement decisions solely on IQ scores b/c there are kids with sky high scores who don't need significant advancement and kids with more mildly gifted scores who do well with advancement. That said, unless the IQ scores you have are quite off, I would expect that she'd be a very good student (as she appears to be), but not so far out of the norm that she needs to skip grades, for instance.
She should fit in and do very well in accelerated/GT classes and have peers there. Her achievement scores from the WJ you posted seem in line with that. She's in 3rd grade? For a 3rd grader, she should be a top student but one who can be accommodated within the classroom again, unless, the scores don't line up with the kid well or her school tends toward lower performing kids.
What I'd look for in scoring, and what I suspect others were wanting to know when asking for all of the subtest scores, is whether the pattern shows major scatter. Major scatter tends toward making the composite numbers less reliable. Scores in the 13-14 range are comfortably gifted and she does have some definite low spots related to speed/motor skills, as someone else mentioned. The difference btwn a 10 and a 14, though, isn't as huge as a kid who, for instance, has scores that go from 7 to 18. I wouldn't be inclined to distrust the overall score you got as a result. B/c her WMI was as high as it was, the GAI probably isn't going to be wildly different from the FSIQ either so it won't give you much more info on ability.
Does she seem truly bored with the material and tremendously more advanced than the other kids in the classroom? Can you go in and observe or volunteer to get a feel for what the rest of the class is capable of doing? If it is a misfit btwn her and the rest of the class, is there another classroom she could move to that might have a better peer group?
Due to the sudden nature of her complaints, I'd also wonder like Coll whether there is something else going on at school that isn't totally related to a need for academic acceleration.
