When my DS was tested at 6, he had similar results. Same PR score, Verbal was just a few points higher. Also, my DS's working memory wasn't that high. Considering almost a 30 point gap between verbal and PR I was concerned but the neuropsych didn't seem concerned. He just called the verbal ability a "relative weakness". He actually seemed more concerned about processing speed which was around 110, saying that DS might appear "slow" but I think it's pretty common for gifted kids to have processing speed scores in the average range. Don't know if that helps.
My DD has an even larger gap. Her PR was around 150 and processing speed 94. I am taking her into a psych to do learning disability testing. We already know she has ADHD but I'm concerned about dysgraphia as well.
