Global PISA scores hit historic low across all subjects, OECD confirms

OECD data shows the latest PISA cycle recorded the lowest average scores in science, math, and reading among 23 historical countries, continuing a decline that began in 2015. The drop is most pronounced in reading (-16 points) and math (-11 points), signaling a systemic deterioration in educational outcomes. The cause is uncertain, but the trend has broad implications for future human capital and economic competitiveness.
