I guess we are of the minority...our (title I funded) elementary school of about 250 students has 2 identified gifted kids (one being our DD). DD7 will hopefully be #3 after we get results from her recent testing. There was one more student, but that child is no longer in the gifted program (for reasons I'm not aware of, but I have my guess). I would love to have a couple more kids identified so they can do some group activities together.
I don't see parents fighting to get their kids in the gifted program - this may be because they don't see the purpose or just that the gifted program isn't really "advertised". I also think most parents have faith in the school that they will do and are doing what is best for their child since they are the educators, so even if they thought their child was gifted if the school says they are not then that is that.
