The striking difference between my experience and that described in the article is that the educational structure of The Center was not competitive. They were just normal elementary school classrooms other than the level of the content. There are only two plausible reasons that I didn't experience the idea that some kids were dumber than others, either it didn't happen or I was the dumbest and the other kids were compassionate and kind.
Five year olds don't feel pressure to get into the best kindergarden. It's some adult's bright idea to sanction eight year olds competing on spelling day in and out. Once a year for the Scripps National Spelling Bee is plenty enough if not too much. My son goes to school with children who don't get dinner if they get a B on a math test and others whose parents have picked their majors before middle school...in STEM of course.
Yet I think the the most awesome of my classmates from all those years ago are an historian and a public school teacher.
