I see that the WPPSI-III is divided by age into 2 years 6 months to 3 years 11 months, and then 4:0 to 7:3. My DD is 3 years 9 months, and one of the options we have for testing her for giftedness is WPPSI. I am wondering whether there are any potential ceiling effects from splitting the test into two by age. The youngest group only do 4 subtests, compared to 7 of the older kids. Some of the missing ones seem to be performance speed related, so skipping them seems good, but some of them sound like they might test reading type stuff, that one wouldn't expect an under-4 to know. It's not that she is reading yet, but she has a lot of pre-reading signs there, and to be honest, I don't totally know *what* she can do. You'd think she couldn't count from talking to her, and yet she breezed through Reader Rabbit Kindergarten, and it didn't look like guesswork or cheating.
