A question. What do the testers that DO NOT use the Stanford Binet-LM do for children that hit the ceiling on the WPPSI? Are there other tests with an extended norm that are commonly used?
Both the WISC-IV and the SB-5 have extended norms-- and even without them they'd probably be a better choice for an advanced little one (less babyfied). The SB-5 can be given to your son at his current age, but you'd have to wait until age 6 for the WISC-IV. The DAS II is another option that can be given as young as 2.5; I'm not sure how high the norms go but I recall DS6 scoring in the 180s on a couple of subtests*, so maybe the higher ranges are just built in.
* I'm not bragging (here of all places), just think it's relevant to the issue of extended scoring. DS was first tested on the DAS II by a school psych, and it went terribly badly-- she reported that he was curled up under his chair claiming he was having stomach pains for much of the test, and he scored so many zeros and single-digit results on some other subtests by refusal to comply that the results were incomplete.
