Is IQ of 130 in WISC -IV really top 2%?

[Anonymous]

Unaware of prepping for WISC. All three of our children have IQs that put them at the top.

Based on my reading, no, but IQ-tests given to very young children can be gamed through preparation given the nature of the tests. This seems to happen often in very competitive testing environments like DC and NYC, and testing at young ages is pretty noisy anyway since one can't expect maximum performance from all children due to lack of motivation, understanding, etc.

IQ is mostly genetic (~70%). The percentage due to genetics is less in early childhood and rises all the way to early adulthood. The rest is due to in utero and environmental differences.

im surprised - I thought 130 was technically above average - not even considered "gifted." I thought gifted was over 140 or so

130+ is 2% of the population. It is not so common.

I think you're underestimating how much "harder" it is to have each additional IQ point above 100, since its a normalized test. E.g. if you have an IQ above 100, there is around a 30% chance you also have an IQ above 115. But if you have an IQ above 130, there is only around a 6% chance that you have an IQ above 145.

By definition, in a normal distribution (aka Bell curve):

Average is 100

One standard deviation above average is 115

Two standard deviations above average is 130 (98 percentile, aka top 2%)

In my case my child's word knowledge and vocabulary (meaning social and practical knowldge) a section in VCI came out to be weak. The other one "similarities" is 92%. Rest are above 90%. I am under impression that WMI,PSI are inherent(genetic) but VCI is environmental like how much exposure child is given. So can VCI be improved by giving good exposure? I might be comapletely wrong. Correct me if I am wrong.

NP here-Can someone answer PP's question? I am also in the same boat

Can't you ask the person who administered the test - I mean you did pay $400!

PP, OP here, thanks for your wonderful advice, I did the WISC 3 months back, this question came in my mind few days back so asking.

Maybe, but probably not by much. These are reasoning scores, not achievement scores. In fact, processing and working memory could see some modest improvement with some therapies-- core intelligence (verbal and non verbal reasoning) is more likely to remain within a certain bandwidth.

I think the new WISC V (my son took it last month) is even less vulnerable to environmental influences or preparation than the WISC IV. My DS took the WISC IV about two years ago, and I much prefer the WISC V.

Yes, you can manipulate the score. Setting aside for a moment whether "core intelligence" is genetic or environmental, all test performance, particularly at a young age, is partially a factor of both preparation and executive function.

Did your child score the same with wisc 4 and 5?
