All of my kids went through gifted programs in their school, and I never saw any problems with them personally, but as a teacher I have seen the ways in which distinguishing some bright children as brighter than others can cause a problem in the education environment. In many school systems (mine included) entrance into the gifted program relies on IQ tests, and an evaluation that a student is gifted, not just bright. Why does it matter? If a student has 125 IQ, not 130, why should they be less challenged? It's been found that many students that don't make it into the gifted programs at their schools are severely under-challenged. When this happens, these students are not given the space they can learn and thrive one. The thing that most makes up for this is inspiring teachers. Many teachers recognize the students that need more encouragement, even without the gifted title, and provide the right encouragement in the classroom. But not every teacher can be expected to have the resource to accomplish this, and education systems need to adjust in order to fit the bill.
