Put those two factors together and a higher percentage of kids than 1 in 100 will score very well. Add to that that parents are going to refer to their kid as 99% if they reached that level on the Verbal, Performance, or Full Scales, not necessarily on all three, and you have a larger-than-expected group at the 99%.

The same thing happens for older kids on the SSAT, although 99% is still pretty rare. You get two scores back - child compared to a national sample and child compared to other applicants to independent schools. A kid at the 95%ile nationally might only be at the 70%ile for private school kids.

You're posting the same messages on several threads right now. I'm very curious about what makes you an expert on this - I really question how many children in this area are scoring 99+ on Full Scale IQ. I questioned you on the other thread too because most independent school children I know scored in the high eighties and low nineties -

Different poster here. I don't think PP claimed to be an expert. Neither am I. But as I stated on another thread, I do know about a dozen kids who scored 99% FSIQ.

FWIW, I know many children who scored in the 80 percentile around here.

Statistically speaking, it makes quite a bit of sense that you would know many children who scored in the 80th percentile. I'm not sure why you find that unusual. I think what many will find come March when the admission letters are mailed is that the scores aren't as huge a factor. There will be some 80-ish percentile children accepted and rejected. There will be some 90-ish percentile children accepted and rejected, included those 99.9% children. You may very well be among those scratching your head wondering how your 86% child got so luck, or how your 99.9% child was 0 for 4.

I am? I'm the PP here, but not the only, or major, poster on these threads.

I tried to answer that exact question. I don't think the majority of kids are scoring at the 99th %ile. I just think it is entirely possible that more than 1% of private school applicants are scoring at the 99th %ile.

I too know plenty of kids who have scores closer to the 90th %ile.

Oh, and I'm a psychologist with a lot of training and experience in testing.

i don't believe that they all got 99%. they probably are just embarrassed to say that their child didn't do as well. seriously, last year, my child didn't get a 99% and although i didn't lie and say she did, i did elude that she did VERY VERY well after someone told me that their child got a 99. this year however, my child actually did get a 99 and the funny thing is now that she did so well, i have no desire to tell or brag to anyone b/c my husband i and i know and have pleasure in just that.

But nationwide, most kids taking the WPPSI are applying to private schools. Similar population to our area. I agree with your point, though, that parents brag about their kids being 99% on one scale, rather than full. I refuse to believe that every parent on this board has a kid who has a FS IQ in the 99% range!

My son's WPPSI score (administered at age 9) was in the mid 80s FS and he attends one of the "big 3s". If supposedly the majority of his classmates have scores in the 99th percentile, I'm scratchin my head as to why he's performing better. Breezing right through his assignments and tests. His teachers have reported to me that he comprehends concepts rather quickly. I'm not buying that he's in a classroom full of genuises.

The percentiles do not come from kids taking the WPPSI now. They come from a sample of kids who were used when the test was being developed - and that sample is carefully matched to the population as a whole. So if your kid is at the 99th percentile, or the 80th, or the 50th, that is compared to the American population as a whole, not compared to other kids applying to private schools.

Who on earth administered the WPPSI to a nine yr old... You do mean the WISC, right? If not, then your nine year should have knocked that test out of the park. Something about your post rings false.

He said a gap of a few points was no big deal, but 9 points seemed to raise some questions.

I don't know why this is odd to me. I think that you are better off without Mr. Mitchell and his gang. The comment "raises questions" about him. What was his score? It is so dumb to focus in on one itty bitty test in determining a child's future.
Your child is FINE, forget them.
Thank god I don't live in DC and have to deal with these people.

No kidding -- does that gap tell them anything, especially with the scores otherwise high? By the logic of Mr. Mitchell, they would prefer a child who scored 90/90 than 99/90?

Now, I can see a red (or yellow) flag for disparities other mentioned here--30 to 50 points, but 9 points?

I remember taking the SAT and I got, I think a very high math score (either 800 or 780) but my verbal wasn't so great (mid 600s). First, I got into top colleges. Second, no one told me that (or thought that) I had some sort of learning problem that I was really good at math but not so really good at english.

Not a false post. Meant the WISC.
