Finland's schools owe their newfound fame primarily to one study: the PISA
survey, conducted every three years by the Organization for Economic
Co-operation and Development (OECD). The survey compares 15-year-olds in
different countries in reading, math, and science. Finland has ranked at or
near the top in all three competencies on every survey since 2000, neck and
neck with superachievers such as South Korea and Singapore. In the most
recent survey in 2009 Finland slipped slightly, with students in Shanghai,
China, taking the best scores, but the Finns are still near the very top.
Throughout the same period, the PISA performance of the United States has
been middling, at best.
