Something you might consider , have him tested with multiple tests. They'll all probably result in comparable scores, but they'll come in within a range. This way, you won't have a single score. At The Gifted Center in Denver, they gave my daughter The DAS II, WISC, and the Binet LM, as well as the Woodcock. All came in high but no single one came in the same. This way, we have a range instead of a single number. You're told that a single score has a +/- , but I know what you mean when you see a single number.
