About those WPPSI scores... This particular Wechsler has a fairly low ceiling, and many kids who take it when they are at the older end of the age range have artificially LOW scores due to the test not being able to measure anything higher.
On the other hand, I have heard professional test administrators say that they take the WPPSI with a grain of salt, as it can also produce artificially HIGH scores due to the age norming. How many four year olds can actually decode and not just recognize a few sight words? Not very many, and that makes the child who reads a bit look extraordinary.
The WPPSI essentially can give the same sort of scores to kid A, reading Dick and Jane, and kid B, reading Ivanhoe. While it is unusual for a four year old to read at all, it is FAR more unusual for a four year old to be reading novels. I think this is why Davidson wants more than just test scores. They can be so ambiguous! Unfortunately, we don't really have anything better at this point.
