Seems from what you guys have responded that the Stanford Binet-LM will have inflated numbers that are not true to his ability. Are these the old numbers? The numbers we as children would have received? I was never tested but my husband was and I have a couple of friends that were. I would assume they would have used the Stanford Binet-LM right?
Yes and no as to whether these are the #s we all would have rec'd as children. Are you familiar with the Flynn Effect? Essentially, if you took the SB-LM as a child and then took it again now (assuming that all was equal and your IQ hadn't changed at all over the years), you'd get a higher number now due to the Flynn Effect. If your child, taking the LM now, gets one number, were he the same child of the same ability in 1975 taking the same test, the number he rec'd would be lower. That's why tests are renormed. See: http://www.indiana.edu/~intell/flynneffect.shtml/
I'd say that pretty much everyone other than the GDC would suggest a different test like the SB-V for kids who hit the ceiling on the WPPSI. I thought that they were working on extended norms for the WPPSI-IV as well, though, and that might be another option. He probably took the WPPSI-III, though, since I'm not sure that they're done with norming version four.
I'd also agree with others that the IQ number alone isn't going to tell you the level of giftedness. Once you get to the tail of the bell curve, there are a lot of other factors that come into play in regard to the level of giftedness.
