One in four students in OECD countries are unable to complete even the most basic reading tasks, meaning they are likely to struggle to find their way through life in an increasingly volatile, digital world. This is one of the findings of the OECD’s latest PISA global education test, which evaluates the quality, equity and efficiency of school systems.The OECD’s PISA 2018 tested around 600,000 15-year-old students in 79 countries and economies on reading, science and mathematics. The main focus was on reading, with most students doing the test on computers.Most countries, particularly in the developed world, have seen little improvement in their performances over the past decade, even though spending on schooling increased by 15% over the same period. In reading, Beijing, Shanghai, Jiangsu and Zhejiang (China), together with Singapore, scored significantly higher than other countries. The top OECD countries were Estonia, Canada, Finland and Ireland.
