Every year, the OECD releases its flagship Education at a Glance report, measuring what percentage of working-age adults — people between 25 and 64 — hold a college or university degree. That single number tells a remarkable story about a country’s values, its economic priorities, and its vision for the future. Based on the most recent 2025 data, here are the ten countries that have climbed the highest on that ladder.
What you’ll discover is that these aren’t just countries with fancy universities. They’re places where governments made deliberate choices — sometimes over decades — to fund education, remove barriers to access, and tie their economic future to their people’s brains. Let’s take a closer look.

The Full Countdown
Norway might surprise some people at number ten — it has, after all, consistently ranked near the top of global happiness and quality-of-life indexes. But when it comes to the raw share of adults holding university qualifications, it sits at roughly 50.4%, an impressive mark that still places it among the world’s most educated societies.
Norway follows what’s known as the Bologna Process for structuring university education: a three-year Bachelor’s, two-year Master’s, and a three-year doctoral programme. Popular disciplines lean toward health and welfare sciences — nursing, physiotherapy, sport science — alongside business administration and the natural sciences.
The government’s decades-long commitment to free or heavily subsidised tuition means that going to university has never been a question of family wealth. That policy has paid enormous dividends in terms of social mobility and workforce quality. Norway’s economy, fuelled by its sovereign wealth fund and oil revenues, has also channelled significant resources back into research and academic infrastructure, making its institutions genuinely world-class.
Sweden has built an education system that isn’t just about producing graduates — it’s about producing citizens capable of thinking critically, collaborating globally, and contributing to a sustainable future. Institutions like Karolinska Institute (one of the world’s most prestigious medical universities) and KTH Royal Institute of Technology have cemented Sweden’s reputation as a genuine hub of academic excellence.
What makes Sweden especially interesting is its emphasis on equality — not just as a social value, but as an educational policy. Women actually outnumber men in Swedish universities, and the gender gap in fields like medicine and law has largely closed. Tuition is free for EU citizens, and the country offers generous student loan and grant programmes, even for international students in some cases.
Sweden is also a world leader in integrating sustainability and digital innovation into its curricula, preparing students not just for today’s jobs but for industries that don’t fully exist yet.
Israel’s appearance in this top 10 is a story of cultural priorities meeting geopolitical necessity. In a region surrounded by complex challenges, Israel made a strategic bet early on: build a knowledge economy. Decades later, that bet has paid off spectacularly — Israel is now one of the world’s leading innovation economies, with more NASDAQ-listed companies per capita than almost anywhere on earth.
One fascinating aspect of Israel’s academic profile is the notably higher representation of women in traditionally male-dominated fields like engineering and computer science — a rarity globally. Israel’s universities are diverse in structure: research universities sit alongside academic colleges and teacher training institutions, catering to a wide range of educational goals.
Roughly 88,200 students graduated from Israeli higher education institutions in the 2021–2022 academic year alone, a remarkable number for a country of under 10 million people. The nation’s mandatory military service also shapes its academic culture — many Israeli students begin university with real-world experience and problem-solving skills that carry through their studies.
The United States is perhaps the most complicated story in this top 10. Home to institutions like Harvard, MIT, Stanford, and over 4,000 colleges and universities, the US has the world’s most recognisable higher education system. And yet its overall tertiary attainment rate of around 50.7% places it seventh, well behind smaller nations that have built more equitable systems.
According to the US Census Bureau data, the most popular degree fields are business management, psychology, nursing, and education. The District of Columbia — home to hundreds of government agencies, think tanks, and policy organisations — has the highest educational attainment of any state or territory, with a massive share of its adult population holding postgraduate qualifications.
America’s challenge has never been quality at the top end — it’s accessibility. The student debt crisis has made higher education a financially fraught decision for millions, even as the economic returns of a degree remain strong. The US continues to attract more international students than any other country, and its research output remains the largest of any single nation on earth.
Few countries carry the weight of academic prestige the way the United Kingdom does. Oxford and Cambridge are over 800 years old — institutions whose alumni include prime ministers, Nobel laureates, and some of the most consequential thinkers in history. The UK’s higher education system consistently dominates global university rankings, and British degrees are recognised and respected in virtually every corner of the world.
British undergraduate degrees are typically completed in three years — a year shorter than in the US or many other countries — reflecting an intensive, focused approach to academic learning. The UK invests heavily in research, and institutions like Imperial College London and UCL sit at the cutting edge of science, medicine, and engineering.
The country has also benefited from a strong tradition of public libraries, lifelong learning programmes, and a cultural attitude that associates education with personal prestige. While tuition fees have increased significantly in recent decades — a point of ongoing political debate — graduate earnings premiums remain among the highest in Europe, keeping demand for degrees robust.
Switzerland does everything carefully, and education is no exception. This small, landlocked country of just under nine million people has somehow managed to host ETH Zurich — consistently ranked among the very best technical universities on earth — and yet what makes Switzerland’s education system truly distinctive is that it doesn’t dismiss vocational education as a second-class option.
Switzerland’s dual-track system — which allows students to pursue either academic university pathways or apprenticeship-based vocational training — is studied and admired by education policymakers worldwide. The result is an economy where skilled tradespeople and engineers are equally valued, and youth unemployment remains among the world’s lowest.
Operating across three major linguistic regions (German, French, and Italian), Swiss universities are uniquely multilingual and internationally diverse. The country spends more on research and development as a percentage of GDP than almost any other nation, and its corporations — from pharmaceuticals to finance — consistently partner with academic institutions to drive applied innovation.
In Japan, the university entrance examination season is a cultural event. Students preparing for these high-stakes tests spend years in juku (cram schools), and the results will shape not just their careers but their social standing. Japan’s relationship with education is intense, meticulous, and deeply embedded in national identity.
About 65% of Japanese adults aged 25–34 hold tertiary qualifications — a striking proportion for a large, populous country. Japan ranks among the top performers in PISA assessments, particularly in mathematics and science, reflecting a foundational primary and secondary system that is rigorous, well-funded, and highly respected.
The University of Tokyo and Kyoto University are considered among Asia’s finest academic institutions. Japan also leads in robotics and advanced manufacturing research, with universities deeply integrated into the country’s technology-driven industrial strategy. Lifelong learning is culturally valued too — continuing education programmes for adults remain popular and well-attended across all age groups.
There’s a Korean phrase — kyoyuk yeol — that translates roughly as “education fever.” It describes the almost feverish intensity with which Korean families invest in academic achievement. Private tutoring is a multi-billion-dollar industry. The university entrance exam, the Suneung, is taken so seriously that aircraft are grounded and construction halts on test day to ensure silence near examination centres.
The results of this national dedication are staggering. About 70% of South Koreans aged 25–34 have completed college, the highest rate in the OECD for that age group. The country’s transformation from a war-devastated economy in 1953 to a technological and educational powerhouse within two generations is one of the most remarkable national development stories in modern history.
Seoul National University, KAIST (Korea Advanced Institute of Science and Technology), and POSTECH are respected globally. South Korean graduates have driven the rise of companies like Samsung, Hyundai, and LG from modest domestic firms to global giants. The criticism sometimes levelled at the system — that it creates pressure-cooker stress among students — is real and acknowledged by Korean policymakers, who are actively exploring reforms.
Canada is quietly, consistently one of the world’s most educated societies — and it rarely makes a fuss about it. With a tertiary education attainment rate that reaches as high as 66.36% when broader categories are measured, Canada sits near the very top of global rankings by almost every methodology applied.
The University of Toronto, McGill University, and the University of British Columbia consistently rank among the world’s top 50 institutions. Canada’s publicly funded education system is accessible and well-resourced from primary school through postgraduate study. Its immigration points system actively rewards higher education credentials, which has also attracted a highly educated immigrant population that contributes to the overall national statistics.
What Canada gets especially right is the balance between academic and applied learning. Its colleges and polytechnics provide world-class vocational training, and community colleges serve as genuine pathways to university education for students who didn’t follow traditional academic routes. The result is a society that is educated broadly and deeply.
Here it is — the unlikely champion. Ireland, a small island nation of just over five million people on the western edge of Europe, tops the OECD’s rankings for the share of working-age adults with at least a Bachelor’s degree, at an extraordinary 52.4%. That’s not a fluke. It’s the result of decades of deliberate policy, cultural transformation, and a quite remarkable national bet on education as the route out of poverty.
In the 1960s, Ireland introduced free secondary education — a move that, within a generation, transformed a country where large swathes of the rural population had minimal formal schooling. By the 1990s, when Ireland’s “Celtic Tiger” economic boom took hold, it was powered almost entirely by a young, well-educated, English-speaking workforce that attracted multinational corporations from every corner of the globe.
Today, Ireland is the European headquarters for Apple, Google, Meta, Pfizer, and dozens of other global giants — companies that chose Dublin not just for tax reasons, but because they could hire graduates who were genuinely among the best-educated in the world. Trinity College Dublin’s Long Room library — one of the most beautiful in existence — serves as something of a national metaphor: ancient, elegant, and absolutely packed with knowledge.
Ireland remains well above the EU average for tertiary attainment across all age groups, and the government continues to expand access to higher education through grants, apprenticeships, and a growing network of technological universities that bring world-class learning to every corner of the island.
What These Countries Have in Common
Look across these ten nations, and a few patterns emerge immediately. Most have made education either free or heavily subsidised at the tertiary level. Most have deep cultural traditions that treat academic achievement as socially valuable, not just economically rewarding. And most have governments that made long-term bets on education investment rather than short-term fiscal cuts.
But perhaps the most striking takeaway is the diversity of the list. Norway is a petro-state that reinvests its oil wealth into public services. South Korea is a country that built its educational culture from near-zero in living memory. Switzerland made vocational and academic tracks equally respected. Ireland transformed itself through secondary school access. Canada built inclusivity into its immigration model. There is no single formula — only the consistent commitment to treating learning as a national priority.
As artificial intelligence reshapes economies and the skills required by the job market, the countries that have invested most deeply in their people’s capacity to learn, adapt, and think critically will likely continue to thrive. Education, it turns out, remains the best investment a nation can make — in its people, and in itself.
