How do math skills compare around the world?
This graphic, via Visual Capitalist’s Bruno Venditti, ranks participating countries and economies by the average mathematics scores of 15-year-old students in the most recent PISA 2025 study, published in September 2026.
PISA assesses students in mathematics, reading, and science. Its mathematics assessment goes beyond memorizing formulas or procedures, measuring whether students can apply mathematical knowledge and reasoning to real-world problems.
More than 760,000 students took part in PISA 2025 across 91 countries and economies, representing roughly 33 million 15-year-olds worldwide.
China in this ranking represents the participating jurisdictions of Beijing, Shanghai, Jiangsu, and Zhejiang. Uzbekistan is excluded because a comparable mathematics score was not reported.
