PISA finds reading and math declines among 15-year-olds
The OECD's PISA 2025 assessment, covering more than 760,000 students across 91 countries, reports big falls in average scores for 15-year-olds: reading is down 28 points and mathematics down 22 points across OECD countries since 2015, while science was broadly stable from 2022 to 2025. The share of low performers rose to one in five from 16 percent in 2022. Results predate the pandemic, show a large socio-economic score gap, and highlight mixed effects of digital tools and AI, with better outcomes when students are taught to assess AI output.
OECD reading scores fell 28 points and mathematics fell 22 points since 2015.
