Apologies if you have covered this already, but what does your DD "look like" in terms of how she is performing at school? What challenges or successes is she having? Does she have any learning disabilities or other diagnoses which may explain the spread? Did the evaluator offer any explanation for the results based on the tests themselves and the evaluator's observations?

Test results are most useful as information when they are part of an overall approach to guide you and your daughter in how to adjust her learning situation to maximize her success.

The full scale IQ and GAI probably aren't very helpful as they aren't able to provide you with guidance.
