Gifted Issues Discussion homepage Forums Identification, Testing & Assessment Early IQ scores vs. later scores

My son is 4.5 and we had his IQ tested in January. I have read that IQ testing this young can give low scores because the child becomes tired before reaching the test ceiling. I'm curious if anyone has had their child tested in early childhood and then later and if you'd be willing to share the different results. Just curious, really. Thanks!

My son was tested on the WPPSI-III at age 4.5 and on the WISC-IV at age 6.5. The results were within 2 points of each other.

My son was tested on the WPPSI-III at 4y10mon and on the SB-V at 7y8mon. The results were within 2 points of each other as well (like CathyA). HTH.

That's very interesting considering that two different tests were used!

My sister once told me that her kids' school had said that early IQ tests are generally [/i]higher[i] (I think they said "inflated") than later results. I asked her for more information, but she didn't know anything more or the source, etc.

I have one DS who tested high on IQ test at age 5 (156), and now doesn't test startlingly well on SATs (which are supposed to correlate). I don't believe his IQ has decreased, but think that he's a slow reader (as am I).

Hi All, We were in a similar boat in that both sets of scores were good but the first set was out of date for some of the programs we were seeking (older than 2 years). I see no need to test IQ again for this child. I, too, was surprised by both the stability and the consistency of the sections that were high (WPPSI-III P and SBV NV) as well as the FSIQs. Anyway, I tend to view all with a grain of salt since potential doesn't necessarily equal performance or success. If there were a magic pill for motivation - that would be something I would be interested in!
Interesting thread...

My DS8 was tested on the WPPSI-III at age 4.2 and WISC-IV at 6.2.
There are 18 points difference between them.

Botchan, which one was lower?

The WPPSI-III was lower.

Yeah! A motivation pill! Well actually let's see....Pokemon, Bakugon and now Yu-Gi-OH are the great motivators around here. :-) We have made our own Pokemonoply board game, a website dedicated to cheat codes for Pokemon Nintendo games, PowerPoints about all the Bakugon figures and now a Card Creator online for making your own Yu-Gi-Oh. This summer has also brought on "Fishing Mania" and that meant purchasing the Field Guide to North American Fishes" which is studied daily for distinguishing marks, areas located, type of feeder etc. as well as a really cool mosaic of a Pumpkin Seed. Myself as Mom, I am just along for the ride. :-)
