Expert: Low test scores not a worry

People should not overreact to the fall in ranking of Chinese students in the 2015 Program for International Student Assessment; they should focus on what the test results indicate about the education system in China, experts said.

Chinese students' scores fell across the board in science, reading and mathematics in the 2015 PISA compared with 2012, although they were able to retain their top-10 ranking in science and math, according to an assessment of results released on Tuesday by the Organization for Economic Cooperation and Development.

The 2015 PISA was taken by about 540,000 students aged 15 in 72 countries and economies on science, math and collaborative problem-solving. In China, students in Beijing, Jiangsu, Guangdong and Shanghai took the two-hour test.
