Because of that difference
-- a big one in the world of educational research -- experts including the Brookings Institution's Tom Loveless have cautioned against lumping PISA results together with other test scores. Loveless serves on the U.S. advisory board for PISA and is a representative to the group that administers TIMSS. ___ SCHOOL TIME Obama's education secretary, Arne Duncan, says American kids don't spend enough time in school. "Our children are competing for jobs against children in India and China today, and those children are going to school 25, 30 percent more than us," Duncan said at Brookings this past week. Obama himself said in March: "Our children spend over a month less in school than children in South Korea every year. If they can do that in South Korea, we can do it right here in the United States of America." The president is in luck: The U.S. already is doing it.
South Koreans do have a longer school year, measured in days. But Americans actually spend more time in school. The average U.S. eighth-grader has 1,146 instructional hours a year, compared with 923 hours a year in South Korea. In fact, the U.S. has more instructional hours than many better-performing countries, though that raises a separate question about how well American schools spend classroom time. A longer school year would shorten summer vacation and perhaps minimize the summer learning loss that hurts struggling students. Duncan is urging school districts to consider a longer year. The school-time data come from the Education Department, which relied on information from the group that administers TIMSS. As for Duncan's comparison, the department says there isn't reliable data on how much time Chinese or Indian children spend in school. ___ GRADUATION RATES Helping more students finish college is a priority among the many philanthropies that work on education issues. In a December speech at George Washington University in Washington, D.C., the younger Gates said the U.S. problem is acute. "In the case of college education, we were No. 1 in the world 20 years ago in the percentage of young adults with a postsecondary credential. Now we're number 10 and dropping," Gates said. Obama said this in March: "In just a single generation, America has fallen from second place to 11th place in the portion of students completing college. That is unfortunate, but it's by no means irreversible." The college figures come from various tables provided by the Paris-based Organization for Economic Cooperation and Development, which runs the PISA test of 15-year-olds. But those figures are misleading for several reasons, said Cliff Adelman, a former Education Department researcher now at the Institute for Higher Education Policy. They are based on entire populations, not on what actually happens to students who enter college in a given year. Graduation rates in a large, growing country such as the U.S. will not look as good as those of a smaller country whose population is declining. Countries have different definitions for who is counted; for example, some exclude noncitizens, while the U.S. includes them. Since 2000, many European countries have switched to three-year degrees from four-to-six year degrees, making their rates look better than before. What about high school? There again, international comparisons present similar problems. Other countries have more complex systems with many different types of high schools and can limit who is admitted. No one disputes that the U.S. high school dropout rate, 1 in 4 kids and worse among minorities, is awful.
But as with other international comparisons, measuring the U.S. against the rest of the world is like comparing apples and oranges.
