China is Cheating the World Student Rankings System Read more: World Student Rankings: China Is Cheating the PISA System

David Stout:

The results from a global exam that evaluates students’ reading, science and math skills are in and, once again, Chinese students appear to be reigning supreme while American students continued to underperform.
But before you shake your head ruefully and scoff at the decline of Western-style education, take a look at how the data is organized.
The OECD’s Program for International Student Assessment (PISA) exams are held every three years. Coming first and third respectively in the 2012 exams are the Chinese cities of Shanghai and Hong Kong.
However, China is uniquely not listed as a country in the rankings — unlike the U.S., Russia, Germany, Australia and other nations judged on the basis of their country-wide performances. Instead, China only shares Shanghai’s score with PISA. (Hong Kong, a Special Autonomous Region of China, sends its own data.)
