This, to me, is a prime example of why it's important when shopping for someone to give assessments to your child, that you look for someone who specializes in high-end students. Personally, I would never consider giving the WPPSI to a 6-year-old demonstrating the kind of abilities Christina's son did.
The WPPSI is normed for students ages 2:6�7:3. Knowing that his skills are most likely advanced for his age, this would put him WAY too close to the upper age level (cognitively) for me. I would more than likely wait till his 6th birthday and then administer the WISC IV which is normed for ages 6:0�16:11. That way he'd have much more "room" to shine. The Stanford-Binet V is also a good option.
