PISA 2025: U.S. reading scores fall 14 points as OECD nations post steep declines
U.S. 15-year-olds' reading scores fell 14 points on the 2025 PISA, matching a broad OECD decline, while math and science held steady.
The OECD released the PISA 2025 results on September 8, 2026. The assessment covered more than 760,000 15-year-old students in 91 countries and economies, the largest PISA cohort to date.

The OECD reported that U.S. average reading scores fell 14 points, a decline it equates to roughly six or seven months of learning, matching the 14-point drop in the OECD average.
Across the OECD, average reading scores fell 28 points between 2015 and 2025, about a year and a half of learning, while mathematics scores fell 22 points over the same period. The share of 15-year-olds who are low performers in science, mathematics, and reading rose to one in five, up from 16 percent in 2022.
