If the school will provide you with a full report, you might get some clues on why the score seems lower than you expected. For example, maybe a particular area brought her score down. That said, one IQ test is just a snapshot of how your DD did on the test at one point in time, and cannot tell the whole story. For example, if the purpose of the IQ test was to get to a certain level to qualify for the early entrance, and the tester felt that your DD was gifted and qualified for the program, she might not have felt it necessary to go further. Then again, your DD could have gotten the same score from a tester who is familiar with GT. I don't think IQ scores ever tell the whole story.
I think it is a good sign that the school does consider both achievement and IQ in making placement decisions. If you are concerned that the school will not do enough to meet your child's needs, and you feel there's a better educational option available, then maybe you have something to worry about re: the scores. But if you think the grade skip plus accelerated math will meet your child's needs for now, I wouldn't worry about test scores.
