We just got my daughter's WISC results back - report to follow and we are getting a dyslexia test done too.

her overall IQ is 130 so very superior,
Verbal Comprehension is 106 (66th centile) average
Perceptional Reasoning is 139 (99.5th centile) very superior
Working Memory is 141 (99.7th centile) very superior
Processing Speed is 109 (73rd centile) average

what reasons could there be for such a high difference in scores?

thank you
