Hi,
I am not an expert, but the 19 score for your DS in vocabulary is at the 'ceiling' (see Hoagies Gifted website for ceilings, although you may know about them already). My understanding is that extended norms apply when you hit a ceiling. So you can ask the tester for the 'raw' score and then look at this bulletin:
http://www.pearsonassessments.com/N...C-8E4A114F7E1F/0/WISCIV_TechReport_7.pdf Your DS's scores are a different pattern from my DD's (which I still don't really understand), but ditto what polarbear said and also our DD has some kind of dysgraphia (indicated I guess by a much lower coding score), which we did not realize for some time--her writing looks nice, but it takes her much longer than other kids. So we try to get some accommodation there if possible (e.g., hoping the teacher lets her answer in phrases rather than complete sentences, keyboarding...). Also has had difficulties with piano (specifically, the precise fingering recommended in her workbook) and possibly keyboarding as well, but not gross motor issues.
Good luck! This is a great site to figure stuff like this out, and since you've joined you can search the old threads--it's amazing (and sometimes discouraging, and sometimes reassuring) how the same issues come up over and over and over again.
