Old Dad, thank you very much for your thoughtful reply. Your advice to pace myself is extremely helpful, as is your advice for going forward in determining the best course in supporting my son and his education. I will work on learning as much as I can about "the system" of our local school and our county's G&T program. I'm sure I will have many questions along the way. I feel very fortunate to have found this forum. I have had trouble to this point finding a group of people who are open to discussing gifted issues and who have a broad knowledge of them.
Zen Scanner, I greatly appreciate your point that showing the test results to the administrators and teachers is necessary. I will plan to bring my son's test results and the school report prepared by the cognitive therapist we met with describing his abilities. Since this test is highly influenced by motor ability, does not include mathematical ability, and doesn't have high enough verbal ceilings, I suspect it does not describe my son's cognitive abilities very well. However, it does place him soundly within the gifted range and hopefully this will help us to get him accelerated instruction and the support he needs so that he does not lose his love of learning and school.
