Interesting thread. My son's elementary school has a high number of students who have scored very well. It was enough to be considered into the gifted program, however, it was only one componet of a matrix.

For the most part, my son's 2E issues didn't persuade me to have him participate in the GT program until middle school. I thought at the time, he needed to learn to manage his time and study skills well before we attacked something more challenging (little did I suspect ADHD problems)

Anyway, I think my son's elementary school also considers only allowing less than 10% to be serviced with a pull out program because, the students will get advance work within the regular classrom
