So you all really don't think parents ever push for inappropriate placement for their own egos? You never see parents live vicariously through their children?
I'm sure there are some but as with everything else, just because there are some does not mean all are that way.
I know my college professor one year used to be a GT teacher in Florida before relocating and teaching at the university I attended. She was telling about one parent whose child was identified as not qualifying for GT based on their testing so they had private testing done. Well he qualified based off the private testing and had to be admitted. Sure that was probably for the egos.
The ego thing goes with sports, music, band, beauty pageants etc. It is not GT. I doubt anyone of you throwing out the ego claim has NEVER bragged on your children or their accomplishments. That bragging is an ego boost to your.
It's becoming more blatant among the upper level classes (honors, AP etc.). Thing is, the kids will tell you "but it's done!" like that's the goal. 
. The point is even just the title of the classes "Gifted and Talented" lends itself to stroking a parent's ego. Even here on this board parents constantly throw out that their child is "in G/T" when they talk about any issue with school. The problem is most of these kids are just really good students and do not meet the true definition of a "gifted" child. I also think that if schools tried to change their course titles to "advanced" classes, which is what most of these programs really are, parents would fight that because they can no longer say that their child is "gifted". Do schools need advanced track programs, Absolutely!! Are 99% of the kids in "Gifted/Talented" classes really "gifted", no.
