Wow. Our experiment is off to a great start—let's see if we can finish it off sooner than expected.
Bob Somerby alerts me that new international test results are in. Here they are:
So are American kids hopelessly behind their peers around the world? It doesn't really look that way to me, though note that not all countries participate in every test. As usual, though, I'm posting the raw data below so you can make up your own mind. The full math/science results are here. The full reading results are here. The full results include more detailed information on what percentage of kids scored at high vs. intermediate levels, as well as some race/gender/state comparisons. Overall, however, U.S. results seem to be about the same no matter how you slice them. Roughly speaking, we're in the bottom half of the top ten.
UPDATE: I included an incomplete table in the original version of this post, which showed American rankings in math and science slightly higher than they should have been. I've corrected both the tables and the text.
UPDATE 2: If you're wondering why the math and science tables don't have 56 entries, it's because several of the "educational systems" are subregions of larger countries, including nine U.S. states and three Canadian provinces. The main table only shows the primary political entities that participated in the testing.
