Writing in Bloomberg BusinessWeek, [Vivek] Wadhwa argues:
"Much is made of the PISA test scores and rankings, but the international differences are actually quite small. Most of the U.S. ranking lags are not even statistically significant. The U.S. falls in the second rank on some measures and into the first on others. It produces more highest-performing students in science and reading than any other country does; in mathematics, it is second only to Japan. Moreover, one has to ask what the test results actually mean in the real world. Do high PISA rankings make students more likely to invent the next iPad? Google? I don't think so."
