Best Education Systems (PISA 2022 Rankings)

PISA (Programme for International Student Assessment)is the OECD's standardized test for 15-year-olds, administered every 3 years in ~80 countries across Math, Reading, and Science. The OECD average is roughly 500 points per subject. Top performers (Singapore, Japan, South Korea, Estonia) consistently score 540+, while the OECD median hovers at 485-495. Scores below 420 indicate significant struggles.

In our set, 🇸🇬 Singapore leads with 560 average. PISA is the single most relevant metric for families considering relocation with school-age children — not because it measures everything about an education system, but because it compares outcomes on a common scale across countries.

Latest cycle: 2022. The next PISA wave is 2025 (results 2026). Note that some countries appear in only math/reading/science but not all three — we report only countries with complete data. Source: OECD PISA via OWID.
