A report released by the Organization for Economic Cooperation and Development shows that Americans are getting dumber compared to their counterparts in other countries.

Among adults age 25 to 34, the U.S. is ninth among industrialized nations in the share of its population that has at least a high school degree. In the same age group, the United States ranks seventh, with Belgium, in the share of people who hold a college degree.

By both measures, the United States was first in the world as recently as 20 years ago, said Barry McGaw, director of education for the Paris-based Organization for [Economic] Cooperation and Development. The 30-nation organization develops the yearly rankings as a way for countries to evaluate their education systems and determine whether to change their policies.

McGaw said that the United States remains atop the “knowledge economy,” one that uses information to produce economic benefits. But, he said, “education’s contribution to that economy is weakening, and you ought to be worrying.”

The report, released Tuesday, bases its conclusions about achievement mainly on international test scores released last December. They show that compared with their peers in Europe, Asia and elsewhere, 15-year-olds in the United States are below average in applying math skills to real-life tasks.

Back in July, we let you know that the dumbing down of America’s children is a result of deliberate changes in the education system.
