Gifted Issues Discussion homepage Forums Identification, Testing & Assessment K MAP Maths 98th percentile & WPPSI-IV FSIQ 110s?

DD6 and DD4 took the WPPSI-IV test last Fall (at 5 and 3) because we were looking at private schools for this Fall. DD4 came out as moderately gifted, which matched well with teacher's observations and mine.

DD6's results really surprised me with an FSIQ in the 110s and percentile in the 70ies. Her lowest score, by 25+ percentile points, was in general knowledge. I was surprised overall because she had hit her motor and verbal milestones so early, including compared to little sis, and had exceptional fine motor skills.

Two weeks after receiving those test results, we received the results from her Fall kindergarten MAP math assessment, where she scored at the 96th percentile. That surprised me too, first because of her WPPSI-IV results, but also because DD6 did not care for Montessori math materials throughout PK4 and some of K, choosing instead to sew buttons and pillows, lots and lots of little pillows. By the end of kindergarten, she's now slightly above-grade in reading, but she gained 20 RIT points in the maths MAP, and is now in the 98th percentile at the Spring assessment.

I don't quite expect DD6 to be gifted, even though I could "hang onto" her MAP scores if I "wanted to believe" she is. I'm posting my questions here because my gifted youngest led me to read this forum, and frankly you guys are wicked smart and steeped deep in the subtleties of testing.

1- Is it common to see a math MAP score of 96-98th percentile on the MAP math assessment, in a child with an FSIQ in the 110s?
2- Is it even plausible that a kindergartner would reach the 98th percentile, when she says herself that some of her classmates do more advanced maths than her (her school's average for that grade is near national average) and without "hothousing" (that I'm consciously aware of)?
3- Could the time (a few hours a week up until Christmas, but none in the last 5 months of the school year) I've let DD6 play on some educational apps on the iPad have brought up her MAP score, even though she hadn't seemed interested in maths otherwise?
4- Is the RIT to percentile rank table different every year? The one I found for 2015-16 doesn't match what's stated on DD6's MAP results report page, or rather it matches the Spring 2017 but not the Fall 2016 correspondence between RIT and rank. [NEVERMIND - I was using a "ruler" found via google, and it isn't accurate]
5- Does a poor performance in one area of the WPPSI-IV test bias the tester, or influence the tested, on the rest of the test? Does a high-testing sibling tested the same morning bias the tester when assessing the other sibling?
6- Is there some sort of inverse relationship between fine motor skills development and IQ?
7- Is it unrealistic wishful thinking to feel that the outcome in general knowledge didn't reflect her abilities? Would you say that other than for the gifted subjects, the information segment is a bit of a crapshoot as far as reflecting how much information is retained from what they're exposed to?
