Kriston - glad to hear you are getting it checked out - you seem to have one of the best "guts" around on this board - so I would definitely go with it.

Also, it would be so awful to have him go into any kind of school testing for gt, or anything else for that matter, without a handle on this question! Very best of luck on this one!!
A bit tangential: I probably had my ds hearing checked 3 times before he even hit school age because most people (preschool teachers, etc.) could not understand his words. Big, long sentences, but pretty mumbly; plus he was pretty loud (still is) and he is mister day-dreamer (superb focus skills) !
Anyway, no real issues with hearing, just listening, but it was good to get it checked out.
Lastly, I too remember getting (pink) glasses around 8th grade and just being astonished at all the little houses down in the valleys we passed on a road trip just a few weeks later. My whole family was tickled.
