Ranking education systems is hard, because most measures count inputs like spending or enrollment rather than results.
One assessment tries to measure what students actually know, and it has become the closest thing to a world championship of schooling.
TL;DR
- In PISA 2022, Singapore scored significantly higher than every other country in mathematics, reading, and science.
- Six East Asian systems led in math, with Estonia the strongest European performer.
- Eighteen countries scored above the OECD average in all three subjects, including the UK and Canada.
The rankings here come from the OECD’s PISA, which tested about 700,000 fifteen-year-olds across 81 education systems.

Singapore scored 575 in mathematics, 543 in reading, and 561 in science, well ahead of the OECD averages of 472, 476, and 485.
The dominance of East Asian systems at the top is the single most consistent pattern in the results.
Why these systems win, and a caveat
The leaders share features like strong teacher quality, high expectations, and broad baseline mastery rather than just a few star students.
But there is an important caveat: PISA 2022 saw an unprecedented drop in the OECD average, as scores fell during the pandemic disruption.
So the 2022 results capture learning during an extraordinary period, and rankings should be read as a snapshot, not a permanent order.
The durable takeaway is that the English-speaking countries are solid performers that trail the East Asian leaders, especially in mathematics, which is why math instruction is such a recurring focus of education debate in all three.
ELI5
Every few years, a test called PISA checks how well 15-year-olds in about 80 countries can do math, reading, and science.
Singapore comes first in everything.
Countries like the UK and Canada do well but not as well as the top East Asian systems, especially in math.
