The U.S. ranks 25th out of 27 countries in the growth of college-aged adults with college degrees over the last decade.

Low PISA (Program of International Student Assessment) scores and other international metrics are often drawn upon to highlight the United States' lackluster standing in higher education rankings. However, what is not discussed often enough is that the U.S. education system isn't just poor--it's getting worse. Between 1999 and 2008 the number of college-aged adults (25-34) with tertiary degrees grew slower than 25 out of 27 countries studied.
