There are a lot of components on the checklist related to "leadership" [not my child!], "sought out by peers", "advanced sense of humor", and other things that don't really relate to my child (perfectionism, boredom with easy work, etc). He is extremely bright, but has weak fine motor skills, and is definitely not a squeaky wheel. He is typically pretty content to sit and do a worksheet that is far too easy for him.
I don't really know how they judge the importance of the checklist vs. the abilities demonstrated by the student. His abilities are quieter, and more under the surface than, say, my daughter (DD4). Everybody around her is much more aware of how advanced she is, because she is a much more social and outgoing kid.
thats interesting, my twin 6 yr old girls are quite different in personalities but the social, outgoing, bubbly girl often comes across as a smart arse who doesnt really fully understand what she is saying/joking about (yet she does) whereas my quiet, perfectionist, lack of leadership girl is the one the teachers had quickly assumed was bright. Turns out they have equivocal IQ's.
