Yes, my bias is that most of the rest of the world does education better than we do these days, although I'm happy to see from your link that math scores for 9 to 13 year olds are getting nominally better. I wonder what happens by the time they turn 17? By that time they seem to be at the same point that they were 35 years ago.
