I know that it is probably not helpful to have expectations or to compare siblings but of course it is hard not to do this.
DD 4.11 recently took the WPPSI IV. Her school needed it sometime this year and I thought it made more sense to do it now and then if we needed to do it again later then she could be tested on the WISC in a couple of years.
Based on my observations of my 2 children, I thought they would be similar but that DD 4 would be higher overall plus more evenly spread. DD 8 was tested at 6 on the WISC (IV I think) and was much higher on the verbal portions. I guess I thought DD 4 would be higher because she just seem to pick up everything a little faster and easier than DD 8. For example, DD 8 was an early talker and knew colors/letters etc very early and was reading by 3y with alot of interest in reading. DD4 was not as intensely curious about reading but spoke even earlier, had maybe 500 words at 18 months instead of around 200-300 and was reading with no obvious effort at all by 2y 4 months. DD4 seems to have stronger interest and ability in math and puzzles although DD8 was/in good as well.
Anyway, with only her sibling as a baseline I guess I made some assumptions about how DD 4 would score. Oh, I should also add that I have had a number of comments from people with alot of experience with gifted kids who warned me that she (DD4) was likely very very high.
Ok, so I wanted to know if that was true as it would impact our school decisions in the next 1-2 years so we had her do the test.
Her scores were :
I believe that a GAI is not needed in her situation although I am curious what it would be assuming it can be calculated for this test. I saw the tables to calculate it for the WISC but not for the WPPSI. If anyone knows how to do it please let me know.
I realize that X is a great number-still quite gifted but hopefully we won't be struggling to find a good fit through school. Also I realize that she is only 4 and she may test differently on a future test. I do think she was pretty cooperative although she has a tendency not to answer anything if she is not sure of the answer. DD8 has a GAI 8 points higher than her full scale score I guess I was used to thinking of her cognitive ability as her GAI score and so I thought DD4 would probably be just higher than that. Maybe I am nitpicking too much and trying to compare apples to oranges with these two tests or just expecting too much from 1-2 hours of testing in both my children's lives. Anyway, just curious of anyone's thoughts about this spread of the subtests, how to do the GAI and/or any observations regarding the WPPSI IV -newer test vs WISC IV-older test and about siblings and how their scores vary.
