Our child has just recently been found eligible after my wife and I made an appeal. At first, we were debating whether to let him undergo another intellectual test like WISC but decided against it because he scored 98% in NNAT2 and we felt another test score wouldn't make a difference. In the end, we put together a recommendation letter from an adult (his aunt, who wrote a well-crafted letter), 3 art works (from school and private art class) and a unique material which our son created himself, a 2-page Book of Jokes. All people we shared his jokes with before laughed hysterically and I think that must have been the reaction of the committee members as well. Bottom line, if you're going to make an appeal, based on our experience, it would really help, I believe, if there's at least one well-written recommendation letter and a creative/unique/unusual work of the student. I think the committee is looking for something that would make the student stand out. Just my 2 cents. BTW, we prayed for God to give us wisdom and my wife suddenly had the insight to ask our child to compile his jokes together
