Education ?

"The Economic Impact of the Achievement Gap in America's Schools" (April 2009) said, "Several other facts paint a worrisome picture. First, the longer American children are in school, the worse they perform compared to their international peers. In recent cross-country comparisons of fourth grade reading, math, and science, US students scored in the top quarter or top half of advanced nations. By age 15 these rankings drop to the bottom half. In other words, American students are farthest behind just as they are about to enter higher education or the workforce."
