Attribution 4.0 International (CC BY 4.0)OECD

The Programme for International Student Assessment (PISA) is an international assessment that measures 15-year-old students' reading, mathematics, and science literacy.

The latest PISA test was conducted in 2022, comprising nearly 700 000 students from 81 OECD Member and partner economies.

The map shows the mean country scores from participating countries in the 2022 test in mathematics, reading and science. The higher the score the higher is the average proficiency level.

Key results:

  • Singapore led globally in mathematics, reading, and science.
  • In mathematics, Singapore, Hong Kong (China), Japan, Korea, Macao (China), and Chinese Taipei significantly outperformed other countries, with 17 more countries exceeding the OECD average.
  • In reading, behind Singapore, Ireland, Estonia, Japan, Korea, and Chinese Taipei excelled, with 14 additional education systems surpassing the OECD average.
  • The top performers in science included Singapore, Japan, Macao (China), Chinese Taipei, Korea, Estonia, Hong Kong (China), and Canada, with 15 more systems above the OECD average.
  • A significant drop in the OECD average performance was observed in the 2022 PISA assessment compared to 2018, especially in mathematics and reading, potentially indicating the impact of COVID-19.
  • Only Brunei Darussalam, Cambodia, the Dominican Republic, and Chinese Taipei showed improvement in all three subjects between PISA 2018 and 2022.
  • A long-term decline in student performance in reading and science began before the pandemic, with mathematics showing a downward trend even before 2018 in several countries.
