We are doing the WPPSI in a month with DS4.5 at the GDC in Denver. Should I expect an underestimate?
A gifted kid at 4.5 might be ok, but at 5 or 6 a gifted kid is sure to bump into the ceiling. For example, it's my understanding that there is no part of the test that demonstrates if the kid is reading. I think a gifted kid who is not challenged at end of kindy stuff is pretty sure to hit the ceilings in a way that makes it hard to tell a 'Gifted' from a 'Highly or Profoundly Gifted' kid. I think that's why the DYS cutoffs are higher for WPPSI are 150 instead of 145.
But if Oil needs an IQ test to prove that her kid should say with her friends in school next year in stead of being held back, then it's totally worth spending the money, because it will likely give a good answer to the 'yes' or 'no' question. (I think Oil mentioned that her DD has the kind of personality that would be likely to show herself on an IQ test at this young age. It just won't be reliable to help tease out the answer of 'should Oil try to get her a skip on top of what she currently has.')
Hope that helps!
