Hi--I'm a school psychologist and my take is this: While the difference between your daughter's Processing Speed score and her scores on the Verbal and Performance Indexes of the WPPSI are statistically significant, the information is not that clinically useful. She is one point away from having a "superior" score on the Processing Speed Index, as she performed better than 90% of her same-aged peers on these tasks. While her Processing Speed score is a "relative" weakness for her, she still has excellent skills in this area! As the previous poster stated, "I wouldn't be too concerned about it".
