China
In February 2006, the government pledged to provide completely free nine-year education, including textbooks and fees. Annual education investment went from less than US$50 billion in 2003 to more than US$250 billion in 2011. However, there remains an inequality in education spending. In 2010, the annual education expenditure per secondary school student in Beijing totalled ¥20,023, while in Guizhou, one of the poorest provinces in China, only totalled ¥3,204. Free compulsory education in China consists of primary school and junior secondary school between the ages of 6 and 15. In 2011, around 81.4% of Chinese have received secondary education. By 2007, there were 396,567 primary schools, 94,116 secondary schools, and 2,236 higher education institutions in China.
Education in China
In the 2009 test of the Programme for International Student Assessment (PISA), a worldwide evaluation of 15-year-old school pupils' scholastic performance by the OECD, Chinese students from Shanghai achieved the best results in mathematics, science and reading. The OECD also found that even in some of the very poor rural areas the performance is close to the OECD average. However, controversy has surrounded the high scores achieved by the Chinese students due to the unusual spread of the numerical data, with suggestions that schools were 'gaming' students for the exams. Also while averages across the breadth of other countries are reported, China's rankings are taken from only a few select districts.
