Thanks for all of the additional information.
Unfortunately, I'm not allowed to see the detailed results until school starts. The only info that I have is that the score was 126. I would imagine that he scored quite well in any part involving mathematical concepts, though. I wish that I could see the detailed results before making the decision to go ahead with the WISC.
I also question the qualifications of the counselors as WASI testers, but there's not much I can do about it at this point. The district psychologist is who is supposed to administer the WISC, and I imagine that he/she only does so very occasionally since it is only given by the district when a parent challenges the result of the WASI.
Would I call his health care insurance provider to find out about getting independent testing? Since the testing is done by a psychologist, would it be covered by insurance? We don't have the means to pay very much for testing, but I would love to be able to have an independent test done by someone actually trained to do this as a frequent part of his/her job.
Thanks again for all of your assistance!
