I've mentioned this before, but it bears repeating: the PISA rankings should measure every child in China, not 'economies' such as Shanghai, Hong Kong and Macau (after all, Canada can't simply send in measurements for the Peel School Board or the Calgary Board of Education, both of which would score similarly well). And even the individual 'econom,ic zone' rankings are misleading. "Shanghai led the world in all three subjects—math, science, and reading. But that ranking is misleading. Shanghai has a school system that excludes most migrant students, the children of families that have moved to the city from rural areas of China. And now for three years running, the OECD and PISA continue to promote a distorted picture of Shanghai's school system by remaining silent on the plight of Chinese migrant children." (Note that TES, a European magazine, reported on December 6 that China has decided to participate as a nation in the next round of PISA tests in 2015.)
