I have a daughter who is gifted, and also cursed with a mood disorder, so maybe my POV is skewed, but I think her elementary education was mostly very suitable. She was identified as gifted in K, but we moved in the middle of the year back to our home state of Massachusetts, where there is little to no gifted education. We were in a district full of high-achieving,super pushy alpha parents with very bright kids, so our elementary school offered no formal gifted program. The principal explained to me that gifted programs in districts like this cause more problems than they solve, and I well believe it!
The lack of formal programming turned out to be a good thing, because the teachers felt free to give individualized instruction to the kids who required acceleration. It wasn’t perfect, and it depended on the teacher year to year, but in general, her educational experience was quite positive.
In middle and high school, it all fell apart because there was more of an emphasis on quantity, rather than content, of work in the top level classes. But in college, things have greatly improved. I don’t think the world will ever be an easy place for a sensitive, highly gifted person, but ease isn’t a very good goal for anyone.
