>while even the Deep South, which has consistently been at the bottom, is going up

Well their PISA scores haven't been going up. In fact they've been going down. So if their education is getting better, it's not showing up in the ability of their students to answer questions that other students seem to be able to answer.

That's kind of what I meant by PISA removing "BS"-ability from the equation. For some reason, on American standardized tests, all our children do great. Then we take PISA with all the other kids in the world, and the truth comes out.

That's also why I think we should all just take Massachusetts' education curriculum and implement it across the nation. Because you talk about demographics, but even when you control for income and race, kids in Massachusetts just flat out do better than our kids. Even just taking all kids at the bottom of the rankings in Massachusetts, they are still doing better than kids at the median of the rankings of many, many other states. (And think about the demographics of kids at the bottom in Boston, Brockton, or Springfield. Come on, admit it man. I'll try to stay politically correct here and just state that those very likely aren't professors' kids at the bottom of the rankings in Massachusetts.)

Massachusetts is so far ahead of all of us that I think I'd be comfortable just saying that they seem to have gotten it right, and we should simply copy it. Because right now, the gap is just getting wider and wider with every round of PISA testing.
