No. I am not American but I have looked into it during one of my random internet tangents. They do not have to teach specific things and have far more freedom with what they can teach.
Also, a school is not putting any other to shame because of weight ability. A school is a place of education primarily.
Well the reason America and China do so well in the Olympics is the number of athletes they can invest money in is higher than other countries. Then look at Americas comparatively embarressing performance in the Paralympics.
Also America's fitness is not exactly that great given their obesity rate is about 2/3s of adults.
Yet education gets you more chance at getting employment than sports be it a degree or apprenticeship. Sports does offer careers but far less.
What do you do at the end of school? Take exams or do coursework throughout the years you are there.
Yes and education is of course important, but the Americans have more support for the kids, you get scholarships and whatnot for being extremely good at American football and probably other sports, which is a shame that we don't follow that route
