Hi! Long time lurker but first time poster. You guys have given so much advice and I've learned a lot by reading so I'm hoping I can get some help. My son recently took the WPPSI. He was 5 years 9 months when he took it. I had wanted to wait and take the WISC when he was old enough but his school wanted the WPPSI-IV so that's what we did.

scores:
Verbal Comprehension
Information - 17
Similarities - 13
Vocabulary - 12
Comprehension - 13

Fluid Reasoning
Matrix Reasoning - 17
Picture Concepts - 16

Visual Spatial
Block Design - 19
Object Assembly - 19

Working Memory
Picture Memory - 9
Zoo Locations - 19

Processing Speed
Bug Search - 12
Cancellation - 15

Verbal Comprehension - 129 - 97 percentile
Visual Spatial - 155 - >99.9 percentile
Fluid Reasoning - 139 - 99.5 percentile
Working Memory - 124 - 95 percentile
Processing Speed - 121 - 95 percentile
Full Scale IQ - 131 - 98 percentile
GAI - 141 - 99.7 percentile

I think the scores are all accurate except for the Picture Memory one in working memory. He had been testing for over an hour at that point and asked for a break immediately after that section. When we chatted during the break he said he starting giving random answers because he was tired of doing it.

I asked the psychologist for a nonverbal index as well but she told me that there was one section they didn't complete a subtest that's part of the nonverbal index so she can't give us a score for that. From what I looked up it seemed that it was a supplemental subtest so a score could be possible but I'm not very familiar with the WPPSI so I don't know if I'm reading it wrong. What are the requirements for substituting one subtest with another? I don't know what's allowed and when I tried asking the psychologist I was told that his scores are overall very high so I shouldn't be concerned about anything. I know she's not used to working with gifted kids though.

Opinions please, how much is the picture memory score going to affect his overall score, like for GAI? With having three subtests scaled scores of 19 and two others at 17 how close to the ceiling was he? If we want a better idea would it be worth getting the WISC when he's older or the Stanford-Binet?

Thanks for any help you all can provide!
