Top Performing Countries in PISA: Trends and Insights

PISA remains the most watched cross-country benchmark for how well 15-year-old students can use mathematics, reading and science in real contexts. The latest released cycle is PISA 2022. It covered about 690,000 students and represented roughly 29 million young people across 81 education systems. For a serious reading of the top performers, a simple “who ranked first?” view is too narrow. The stronger question is this: which systems combine high mean scores, a large top-performing group, a small low-performing group, and a fairer link between results and social background?

What Matters Before Reading Any PISA Table

  • Latest core-domain release: PISA 2022.
  • Main subject in that cycle: mathematics.
  • OECD averages: 472 in mathematics, 476 in reading, 485 in science.
  • Clear single leader in 2022: Singapore in all three core subjects.
  • Next full cycle already in motion: PISA 2025 results are scheduled for release in 2026.

PISA also does not publish one combined overall score for all subjects together. It reports a separate score for each subject, and the OECD advises care with exact rank language because results come from samples, not from every student in a country. That detail changes how a “top performing countries” article should be read. [Source-9✅]

Where The 2022 Leaders Stood

The most useful way to compare the front of the table is by subject profile, not by an invented total. In mathematics, Singapore scored 575 and outperformed all other participants. In reading and science, Singapore also led with 543 and 561. Behind that single leader, the leading band shifts by subject, which is exactly why careful PISA reading should stay subject-specific.

Among OECD members, Estonia remains the cleanest all-round European performer, with 510 in mathematics, 511 in reading and 526 in science. Japan and Korea stay ahead on mathematics and science. Ireland is still a reading stand-out at 516. Canada remains strong in reading and science, while Switzerland leans more toward mathematics. Finland, still above the OECD average in reading and science, no longer looks mathematics-led. [Source-3✅]

Why Singapore Sits Apart

Singapore is not merely first by mean score. It also has unusual depth. In PISA 2022, 41% of students reached Level 5 or 6 in mathematics, compared with an OECD average of 9%. In reading, 23% reached Level 5 or higher, against an OECD average of 7%. In science, 24% reached Level 5 or 6, while the OECD average was again 7%. That mix matters because it shows a system with a very large upper tail, not a narrow elite pulling up the mean on its own. [Source-4✅]

There is another point, easy to miss in short ranking articles. Singapore did not arrive at the top only because others fell. OECD material notes that Singapore kept moving up in reading and science from 2018 to 2022 while staying steady in mathematics. That makes Singapore the clearest case of a system that held a very high base and still pushed further. [Source-5✅]

The Patterns Behind The Leading Group

Mathematics Still Has a Clear East Asian Center

PISA 2022 mathematics was not led by a scattered set of countries. It had a clear center. Six East Asian systems produced the largest shares of top performers in mathematics: Singapore (41%), Chinese Taipei (32%), Macao (China) (29%), Hong Kong (China) (27%), Japan (23%) and Korea (23%). Only 16 of the 81 participating systems had more than 10% of students at Level 5 or 6. Put plainly, the highest mathematics tier is still hard to access for most systems; a few stand far above the rest. [Source-6✅]

The front of the mathematics table is not only about the top end. It is also about how small the struggling group is. In six systems, 15% or fewer students fell below Level 2 in mathematics: Estonia, Chinese Taipei, Hong Kong (China), Japan, Macao (China) and Singapore. That pairing — many students at the top and relatively few below the baseline — is what turns a strong mean score into a durable profile. [Source-6✅]

Reading Is Broader Than The Usual Math Story

Reading leadership is more spread out. Singapore still leads, but the next band is not limited to one regional pattern. Ireland sits right near the front, on a similar level to Estonia, Japan, Korea and Chinese Taipei. This matters because it shows that the road to strong reading results is less regionally concentrated than the road to very high mathematics results. Different language environments and school traditions can still produce strong literacy outcomes. [Source-2✅]

Science Mixes East Asia With Smaller High-Income Systems

Science looks different again. The leading science band includes the same East Asian front-runners, yet Canada and Estonia join them, and Finland performs on a similar level to Canada. That tells us the science map is not a copy of the mathematics map. Systems that do not sit at the very top in mathematics can still occupy the front band in science through a different balance of curriculum, instruction and student profile. [Source-2✅]

PISA Should Not Be Read As One Total Score

A frequent mistake in public discussion is to turn PISA into one overall national score. The OECD does not do that. It reports separate subject scores, and it also warns against overly rigid “exact rank” language because sample-based estimates carry uncertainty. So the right reading is not “Country X is number 4 overall.” The right reading is closer to this: Country X belongs to the front band in mathematics and science, but not quite in reading — or the reverse. [Source-9✅]

What The Trend Lines Say

The biggest headline from PISA 2022 is not about one country passing another by a few points. It is the broad OECD decline from 2018 to 2022: minus 15 points in mathematics and minus 10 points in reading, while science was roughly flat on average. The OECD treats that mathematics drop as unusually large by PISA standards. Just as important, the OECD also notes that reading and science had already been sliding before the pandemic years. So the 2022 picture reflects both the shock of disruption and a longer loss of momentum. [Source-7✅]

At the same time, the trend story is not uniform. The OECD reports that 31 systems managed to at least maintain their mathematics performance from 2018 to 2022. Over the full PISA period through 2022, only four systems improved in all three core subjects: Colombia, Macao (China), Peru and Qatar. Four others improved in two out of three: Israel, the Republic of Moldova, Singapore and Türkiye. For a top-performer article, the lesson is clear: Macao (China) and Singapore are not just high scorers; they also stand out in the longer trend data. [Source-8✅]

Any comparison between the 2018 and 2022 headlines also needs one careful note. In PISA 2018, B-S-J-Z (China) and Singapore were the highest-performing systems across the core subjects. In PISA 2022, the Chinese regional participants from 2018 were part of the programme but could not collect data during the intended period because schools were closed. That means the shift from “B-S-J-Z and Singapore” to “Singapore alone at the top” should be read with that reporting break in mind. [Source-10✅] [Source-9✅]

Equity Separates Durable Leaders From Simple Score Leaders

A high mean score by itself is not enough. The OECD’s 2024 work on fairness shows that 10 systems combined a large share of students reaching basic proficiency in mathematics, reading and science with comparatively fairer social outcomes: Canada, Denmark, Finland, Hong Kong (China), Ireland, Japan, Korea, Latvia, Macao (China) and the United Kingdom. This matters because it shifts the conversation from raw scores to something harder and more useful: high performance with a weaker tie between family background and results. [Source-11✅]

The equity chapter in Volume I sharpens the point. Across OECD countries, socio-economic status explains about 15% of the variation in mathematics results. Yet in 14 systems that share falls below 7%. Two cases stand out at the front: Hong Kong (China) and Macao (China) combine mathematics scores of 540 or higher with less than 6% of score variation linked to socio-economic status. Very few systems sit that high while keeping the social gradient that weak. [Source-12✅]

This is one of the clearest lessons in the whole PISA release. A system can post fairer outcomes and still have weak absolute performance. The more interesting cases are the ones that do both: keep the social gradient milder and stay near the front of the table. In 2022, Macao (China), Hong Kong (China), Japan and Korea deserve extra attention for that reason. [Source-12✅]

Resilience After The Shock Years

PISA 2022 added another layer to the top-performer story: resilience. Systems that coped better during and after school closures tended to keep more students in school for longer, faced fewer obstacles in remote learning, and built stronger parent-school links. The OECD singled out Japan, Korea, Lithuania and Chinese Taipei as resilient in mathematics performance, equity and student well-being. That list is useful because it shows that the best systems are not only those with the highest scores, but also those that protected learning and school experience under pressure. [Source-13✅]

That resilience lens also helps explain why some front-running systems held their position better than others. Score tables show the outcome. Volume II gives more of the mechanism: shorter closures, fewer remote-learning barriers, and steadier student belonging at school. For trend reading, that is more useful than guessing from rankings alone. [Source-13✅]

The 2024 Creative Thinking Release Changes The Map Slightly

The 2024 release on creative thinking added a dimension that many country-ranking articles leave out. Singapore again came first. Another 11 systems performed above the OECD average: Korea, Canada, Australia, New Zealand, Estonia, Finland, Denmark, Latvia, Belgium, Poland and Portugal. This widens the picture. A country may be near the front in the core academic domains, yet the creative thinking map can bring a somewhat different set of systems closer to the lead group. [Source-14✅]

That does not weaken the importance of mathematics, reading and science. It simply reminds the reader that “top performing” depends on what, exactly, is being measured. In 2026, this broader reading matters more, not less. [Source-14✅]

What The PISA Leaders Suggest In 2026

  1. There is no honest single overall table. PISA is best read by subject, by performance band, and by trend over time.
  2. The strongest systems protect both ends of the distribution. They do not only produce elite scorers; they also keep the share below baseline relatively low.
  3. East Asia still owns the front of mathematics. Yet reading and science open more space for systems such as Ireland, Estonia, Canada and Finland.
  4. Equity is not a side issue. Macao (China), Hong Kong (China), Japan and Korea show why the tightest reading of educational strength needs both high scores and a weaker tie to family background.
  5. Resilience now belongs in any serious PISA discussion. After the disruption years, score tables without school-closure, remote-learning and well-being context leave out too much.
  6. Singapore is the clearest all-round benchmark in the latest release. It leads the three core subjects, shows a very large top-performing group, and also leads the creative thinking release.
  7. The next major reset is close. PISA 2025 results are due in 2026, so any current article should treat PISA 2022 as the latest released benchmark, not the last word forever.

Read this way, the current PISA map becomes sharper. Singapore is the standout benchmark. Macao (China), Japan, Korea, Hong Kong (China) and Chinese Taipei anchor the upper mathematics tier. Estonia, Ireland, Canada, Switzerland and Finland show that the most durable strength inside the OECD is not one model, but a small set of different profiles that still arrive near the front.
