Hi Leslie- welcome! I am kind of new here myself- there are some very knowledgable posters here who I'm sure will chime in! I can't speak to everything in your post, but I can speak to the Cogat scores. My DS 10 took the Cogat twice upon gifted referral based on some achievement test scores- he did not make the gifted cut either time. We later discovered that this test can miss gifted kids, as he didn't finish any of the subtests, but what he did answer was nearly 100%! He later had the KBIT that yielded a score in the gifted range , then a full scale score in line with that score. So I wouldn't trust the Cogat due to group setting and nature of the time limits. I hope you get some answers - he sounds like a very smart boy!
