Placed from 2 of 4 key statistics
Not placed in the Country Index 2026 overall: measured on too few topics.
01The evidence
Only these place Cook Islands on education & knowledge — one vote each. Every value is the publisher’s own, read at the edition the Country Index 2026 used — or, for a survey-based key, each country’s latest reading; the grey ticks are every other country it was compared with, lowest on the left.
Key 1 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.

No reading
Upper secondary completion rate (%)
Higher is better
UIS publishes no 2025 figure for Cook Islands, so the standing rests on the other keys.
Across the 164 countries in this edition, values run from 2.13 (South Sudan) to 99.27 (South Korea); the world median is 64.87.
Each grey tick is one of 164 countries in the 2025 edition.
Key 2 of 4
UNESCO Institute for Statistics (UIS)
Why it is a key: Whether 15- to 24-year-olds can read and write — the only key here that tests what a schooling system produced, rather than how many passed through it or what it cost.

UIS publishes no reading from 2014–2024 for Cook Islands, so the standing rests on the other keys.
Across the 174 countries at their latest reading, values run from 36.7 (South Sudan) to 100 (Uzbekistan); the world median is 98.22.
Each grey tick is one of 174 countries at its latest reading, 2014–2024.
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.

02Over time
Each key’s published value, edition by edition, beside the world median. The Country Index 2026 is the first edition of the standing, so the standing itself has no history to chart yet.

03In context
A position reads best beside the countries around it. Every position below is a place among all 171 countries on education & knowledge, never a place within the region.
Cook Islands has no land border, so the table compares it with its sub-region. The standing is each country’s place among all 171 placed on the topic; the other columns are the publishers’ own values, read at the edition the standing used.

05Country Index 2026
Education & Knowledge is Cook Islands’s 2nd best-placed topic of 4. Strongest first; each marker sits at the position divided by that topic’s field, so fields of different sizes compare fairly.
No standing on Governance & Institutions, Economy & Innovation, Work & Labour, Environment & Sustainability, Gender & Equality, Democracy & Civil Liberties, Peace & Security, Risk & Resilience, Mobility & Trade, Food & Agriculture, Poverty & Inequality, Digital & Technology: too few of those topics’ key statistics are published for this country.

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.
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 5 statistics on this page come from 1 publisher, 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.
