The results of the 2025 PISA study, published on September 8, show a dramatic drop in performance in reading and mathematics around the world.
The Program for International Student Assessment, better known as PISA, is a global study that measures how well 15-year-old students can apply their knowledge and skills in reading, mathematics and science to real-life situations. The test is designed to measure problem-solving skills rather than evaluate students on memorized school facts, which means they cannot revise in preparation for it.
First administered in 2000, it is considered the world's most influential measure of educational performance.
In 2025, more than 760,000 students in 91 countries and economies took the test.
The study always includes in its ranking the average of the international group of 38 advanced, high-income countries that are part of the Organization for Economic Co-operation and Development, the OECD.
