DASII is well enough known and trusted for DYS to have it as one of their 4 accepted IQ tests:
Differential Abilities Scale-II (DAS-II) Standard Score 145+ (99.9th percentile) on at least one of the following sections: General Conceptual Ability, Verbal Ability, or Nonverbal Reasoning
So that's good.
You can't do WISC IV until age 6, and I definitly wouldn't recommend WIPPSI for your DD at this age - she's too close to the ceiling.
I don't know about SB/spatial skills vs. WISC/verbal - wish I did.
I think it might be more that WISC really relys on a child being 'not shy' and 'talkative' for those verbal subscores and I think it does underestimate verbal intelligence for the shy ones.
Any test will underestimate scores for a child who doesn't cooperate - which brings me to 'chemistry' - it's crutial, particular for your DD, that the tester be someone she matches with - if she gets silly or distracted during the test then there isn't much you'll learn.
Sometimes testers who 'specialize' in kids with learning disabilities or on the lower end of the IQ spectrum can have an 'in-awe' vibe that is a big turn-off for some G kids. We ran into that with the school psychologist, she was totally unprepared for how long the test was taking, and I think she was getting tired before he was! My son does best with someone who is respectful and charasmatic, someone who doesn't 'talk down' to him, and just naturally inspires my son to work hard. And the tester would need not to be thrown by the 'intensity factor' - I've seen some get totally distracted by how 'much' my son can be, particularly when he is trying hard.
Hope that helps!
