Positions out of 182. A standing is relative: it says where a country places against the others measured, not that it scored zero.
02The subject
What a country teaches and how far its people get. Whether children are in school at all, whether they start before primary age, whether the ones who start actually finish, how many years of schooling a child entering today can expect, what the state spends to provide it, and how many adults can read. These are the slowest investments a country makes: the spending is counted now and the result arrives a generation later, which is why the two are measured separately here.
Education is measured here as a journey with a floor and a destination. The floor is whether children of primary age are in school at all; the destination is whether those who start actually finish, first primary school and then the upper secondary years that open the way to further study and skilled work.
Alongside that reach sits what a state chooses to invest. Spending is an input rather than a result, and it is kept separate from completion because the two arrive a generation apart: the money is counted now, and the adults it educates appear years later.
What this topic does not measure
How much children actually learn is only partly covered. International test scores exist for a limited group of countries, and they are published here as context rather than used as a key, because a key must describe most of the world. Universities, research and adult literacy also appear as context.
03The evidence
These are the only statistics that place countries on education & knowledge — one vote each. Every number is somebody else’s research, reproduced without adjustment; the ordering on top is this site’s.
Key 1 of 4
UNESCO Institute for Statistics (UIS)
Why it is a key: Whether children who start school actually finish it — the other three keys measure access, an early start and money, and none of them says anyone completed anything.
Key 2 of 4
UNESCO Institute for Statistics (UIS)
Why it is a key: How far a schooling system carries the young people who get through primary — the only key here that measures anything past childhood.
Current leader, 2025 editionSouth Korea
Key 3 of 4
UNESCO Institute for Statistics (UIS)
Why it is a key: What a state chooses to spend on education, as a share of its economy — the input, where the other two keys measure reach.

Key 4 of 4
UNESCO Institute for Statistics (UIS)
Why it is a key: Primary-age children who are not in school at all: the floor of an education system.

How the keys combine
Each country’s value on each key becomes its place in that key’s own field, as a share of the field. The shares are averaged, one vote per key, and only the order that produces is published.

Each holds readings on too few of this topic’s key statistics to be placed. Their profiles still show every reading the publishers give.
06Beyond the headline
The countries placed furthest above and below their overall position in the Country Index 2026. Both positions are compared as a share of their own field, because 50th of 193 and 50th of 174 are not the same showing.

South Korea, of the 182 countries given a standing on Education & Knowledge. The standing is this site’s own, built from 4 key statistics by 3 publishers; it is not a rank any of those publishers printed.
South Sudan, 182nd of 182. A standing says how a country places against the others measured alongside it, so it moves when they move.
Primary Completion Rate, Upper Secondary Completion Rate, Government Spending on Education, Out-of-School Rate, Primary. Each is read at one edition and turned into a place within its own field; the places are averaged with one vote each. The other 15 statistics on this topic are published as context and have no vote.
A country needs readings on at least 2 of the 4 key statistics before it is placed. 42 countries in the Country Index fall short on this topic; every reading the publishers do give for them is still on their profiles.
The underlying numbers and any printed ranks are the publishers’, reproduced without adjustment on each statistic’s page. The standing that combines them is this site’s, and the average it is ordered by is never published — only the position it produces.
A standing is a place in a list, not a mark out of anything. This one is part of the Country Index 2026, and it is worked out like this.
The other 15 statistics on this page come from 3 publishers, each named beside its numbers, with every edition and licence on the datasets pages.
The standing itself is part of the Country Index 2026, published under CC BY-SA 4.0.
