The thing is “how do other countries measure their education results”. What if every student in America is measured but other countries only measure from their very best schools? I do believe that education has fallen off in America since I was in school but I find it hard to believe that we are that bad relative to the rest of the world.

There are people who claim that China’s city of Shanghai is actually doing this.
