Here is a new snapshot of how the world's 15-year-olds are performing.
The OECD's Programme for International Student Assessment (PISA) measures students' ability to apply their knowledge in reading, mathematics and science to real-life challenges.
Released on Sept. 8, the PISA 2025 results cover 91 countries and economies. Average scores across OECD countries in science, mathematics and reading were at their lowest levels on record.
China's participating mainland regions (Beijing, Shanghai, Jiangsu and Zhejiang), assessed together as B-S-J-Z (China), ranked among the top three by mean score in all assessed domains.
