From the Finnish Miracle to the COVID Collapse — How the Rankings Changed
The history of global education rankings is not a stable table. Countries rise and fall. COVID disrupted everything. And the countries that improve fastest are not always the ones people expect. Source: OECD PISA 2022 (primary · oecd.org).
2000
Launch
First PISA Rankings — Finland Is #1. The World Wants to Know Its Secret.
The OECD published the first PISA results in 2000. Finland topped the charts. Educators from across the world flew to Helsinki to study its formula: master’s degrees for all teachers, no standardised testing until age 16, minimal homework, and a deep cultural respect for learning. The “Finnish miracle” became the world’s most famous education story.

East Asia rises
Singapore, China and East Asia Take Over the Top Spots
By 2009, Shanghai (China) topped the rankings, shocking the West. Singapore — already strong — became consistently dominant through 2015 and beyond. Japan, South Korea, Hong Kong, and Taiwan formed an East Asian cluster that proved remarkably durable. The conversation shifted from “what can we learn from Finland?” to “what can we learn from Singapore?”

COVID crash
COVID Hits. OECD Maths Falls 15 Points — A Record. Jordan Loses 57 Points in One Cycle.
The 2022 PISA results measured the pandemic’s damage. The global maths average fell 15 points — the largest single-cycle decline ever recorded, equivalent to three quarters of a school year. Reading fell 10 points, twice the previous record. But the decline was not equal: Jordan fell 57 points, Albania 53. Taiwan gained 16 points. Japan gained 13. COVID amplified existing structural differences rather than creating new ones.

Singapore led all three domains for the third consecutive cycle with widening margins. 18 countries scored above average in maths, reading AND science simultaneously. Estonia stood as Europe’s best performer. Finland, once #1, sat in the middle of the European pack. The US ranked 18th overall despite dominating global university rankings — the K-12 versus higher education paradox in sharp relief.

PISA 2025 Releases September 8, 2026 — Can Anyone Catch Singapore?
The OECD confirmed PISA 2025 results will be released on September 8, 2026. The focal domain this cycle is science. More than 90 countries and economies are participating — the largest PISA ever. PISA 2025 also introduces a Foreign Language Assessment and a new domain measuring learning in the digital world. Rankings will change. This article will be updated.
Releases September 8, 202690+ countries participatingFocal domain: science
There is no single definitive global education ranking. Different organisations measure different things. But the OECD’s PISA test — given to 15-year-olds every three years across 81 countries — is the most widely accepted measure of how well school systems actually teach students to apply knowledge to real problems. It is the closest thing education has to a world championship.

575
Singapore’s PISA 2022 maths score of 575 is the highest any country has achieved in any single domain in the test’s 25-year history. It leads in reading and science too.
The OECD confirmed Singapore scored “significantly higher, on average, than all other countries and economies” in all three subjects. Its most remarkable feature is equity: even students from Singapore’s poorest households score above the overall OECD average. No other country in the 81-nation dataset can make that claim. 24% of Singapore students are top science performers, against an OECD average of 7%.
Source: OECD — “PISA 2022 Results (Volume I): How did countries perform in PISA?” (primary · directly fetched · oecd.org · December 5, 2023 · 690,000 students · 81 education systems)
“Even Singapore’s poorest students outscore the average student in most rich countries. That is the most important education statistic in the world — and almost nobody talks about it.”
Finland’s Fall — From #1 to the Middle of the European Pack
Finland topped the very first PISA rankings in 2000. For a decade, it was education’s gold standard. Governments sent delegations to Helsinki. Books were written about its formula. But Finland has declined in every PISA cycle since its peak. In 2022, it scored 484 in maths — 21 points below its 2018 result. It remains above the OECD average, but it is no longer near the elite. The Finnish formula did not fail overnight. It eroded slowly. The lesson: even the best systems can drift without sustained attention and adaptation.
Why it matters: Finland’s decline shows that education rankings are not permanent — they require active maintenance, and systems that coast on reputation tend to slide.

−15
Global maths performance fell a record 15 points between 2018 and 2022 — the largest single-cycle decline ever recorded, equivalent to three quarters of a school year lost.
Reading fell 10 points — twice the previous record. Science held steady. The OECD confirmed this was the COVID aftermath — but also noted that countries with structural weaknesses fell further. Jordan lost 57 points. Albania lost 53. Meanwhile, Taiwan gained 16 and Japan gained 13 — suggesting strong systems can weather disruption. COVID did not level the playing field. It steepened the gradient between stronger and weaker systems.

Estonia: The Country Nobody Expected to Top Europe
Estonia has 1.3 million people. Most people cannot find it on a map. It has topped European education rankings for three consecutive PISA cycles. In 2022 it scored 510 in maths, 511 in reading, and 526 in science — comfortably above every Western European nation. Its formula: digital-first teaching since the 1990s, high teacher status, a culture that treats education as a national priority, and minimal performance gaps between schools. Estonia offers a quiet counter-argument to the idea that only large, wealthy nations can achieve educational excellence.
Why it matters: Estonia proves that small, resource-limited countries can build world-class education systems — if they make the right structural choices early and sustain them.
OECD PISA 2022 · Equity Finding · Primary
7×
Disadvantaged students are seven times more likely than advantaged students to fail basic mathematics across OECD countries — but 10% of disadvantaged students still score in the top quarter.
The equity gap in education is one of the most consistent findings in the PISA dataset. But Singapore demonstrates it can be narrowed dramatically — its bottom socioeconomic quartile still scores above the OECD average. This is not inevitable. It is a policy choice. The 10% of disadvantaged students who score in the top quarter show the potential that can be unlocked when systems invest in equity rather than just performance.
