YES, he is gifted and probably frustrated since it has gone mostly unacknowledged by many at school. What a shame!
I would take WISC results over CogAT results any day of the week. In fact, CogAT results can negatively correlate with WISC scores for some gifted students (
http://www.hoagiesgifted.org/why_test.htm). Does your school really not acknowledge the WISC? So here is a school that saw "something" in him, but they won't acknowledge the WISC results? As for the TTCT...meh, not sure it is terribly useful.
So, welcome! Keep advocating for your DS!
