U.S. Schools Are Still Ahead—Way Ahead

Rankings Reconsidered

And then there is the matter of the PISA rankings that supposedly show the U.S. trailing the rest of the world. Hal Salzman, a professor at Rutgers' John J. Heidrich Center for Workforce Development, debunked myths about these in a May 2008 article in Nature magazine. Salzman noted that international tests use different sampling criteria from country to country, so we're not always comparing apples to apples. As well, the tests compare select populations of small countries such as Singapore and Finland, which each have about 5 million people, with the U.S., which has 310 million. These countries achieve the top rankings on the PISA list. Compare these countries to similar-sized U.S. states, however, and you find that some of those states, including Massachusetts (population 6.5 million), produce the top students. Additionally, we're comparing America's diverse population—which includes disadvantaged minorities and unskilled immigrants with little education—with the homogeneous populations of countries like Finland, Japan, and New Zealand.

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 (GOOG)? I don't think so.

Let's keep improving our education system and focus, in particular, on disadvantaged groups. Education is the future of our nation. But let's get over our inferiority complex. America is second to none. Rather than in mastery of facts learned by rote and great numbers of accomplished martinets, its strength lies in the diversity and innovation that arise in an open, creative society.
