01The evidence
The 4 key statistics that decide it
Only these place Slovenia 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
Out-of-School Rate, Primary
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.
Latest reading per country, 2014–2024 · Slovenia’s is from 2023 · CC BY-SA 4.0

Out-of-school rate, primary age (%)
Lower is better
Slovenia: 1.447. Across the 192 countries at their latest reading, values run from 0.004 (United Arab Emirates) to 65.6 (Equatorial Guinea); the world median is 3.691.

Key 2 of 4
Participation in Organised Learning One Year Before Primary
UNESCO Institute for Statistics (UIS)
Why it is a key: Whether children take part in organised learning in the year before primary school — whether an education system reaches them before it starts.

Key 3 of 4
Upper Secondary Completion Rate
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.

93.2

Slovenia: 93.2. 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.

Key 4 of 4
Government Spending on Education
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.
2023 edition · data for 2023 · CC BY-SA 4.0
No reading
Government expenditure on education (% of GDP)
Higher is better
UIS publishes no 2023 figure for Slovenia, so the standing rests on the other keys.
Across the 123 countries in this edition, values run from 0 (Somalia) to 16.39 (Kiribati); the world median is 3.709.

07Questions
Slovenia on education & knowledge: questions answered
Every answer is built from the numbers on this page, so none can say something the page does not.
How does Slovenia rank on education & knowledge?
Slovenia is placed 22nd of 198 countries on Education & Knowledge in the Country Index 2026, from 3 of its 4 key statistics (Out-of-School Rate, Primary, Participation in Organised Learning One Year Before Primary and Upper Secondary Completion Rate). The position is this site’s ordering of published statistics, not a rank any publisher printed.
What is the latest Out-of-School Rate, Primary figure for Slovenia?
1.447 in 2024 (out-of-school rate, primary age (%)), according to UNESCO Institute for Statistics (UIS). The world median in the same edition was 3.691.
What is the latest Participation in Organised Learning One Year Before Primary figure for Slovenia?
95.37 in 2024 (children one year before primary entry age in organised learning (%)), according to UNESCO Institute for Statistics (UIS). The world median in the same edition was 85.9.
How does Slovenia compare with Italy on education & knowledge?
Italy is placed 46th of 198, and Slovenia 22nd. Out-of-School Rate, Primary: Italy 2.056, Slovenia 1.447; Participation in Organised Learning One Year Before Primary: Italy 95.2, Slovenia 95.37; Upper Secondary Completion Rate: Italy 87.5, Slovenia 93.2.
How have Slovenia’s education & knowledge figures changed?
Out-of-School Rate, Primary fell from 2.287 in 2001 to 1.447 in 2023; Participation in Organised Learning One Year Before Primary fell from 99.99 in 2003 to 95.37 in 2023; Upper Secondary Completion Rate rose from 87.26 in 2000 to 93.2 in 2025; Government Spending on Education fell from 5.815 in 2001 to 5.281 in 2022.
Which education & knowledge statistics are missing for Slovenia?
No current reading is published for Slovenia on Gender Parity Index, Tertiary Enrolment, Government Spending on Education, Inbound Mobility Rate, Tertiary, Out-of-School Rate, Lower Secondary Age, Out-of-School Rate, Primary, Participation in Organised Learning One Year Before Primary, Pre-Primary Net Enrolment Rate, Pupils per Qualified Teacher, Primary, Qualified Teachers in Primary Education, School Life Expectancy, Secondary School Enrolment, Tertiary Enrolment Ratio and Wealth Parity Index, Lower Secondary Completion.

09Method
Method, sources and how to cite
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 youth and adult literacy also appear as context.
How the Education & Knowledge standing is decided, step by step
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.
- A few key indicators decide it; the rest are context. 4 indicators on this topic are keys and 42 are charted alongside them without a vote. That split is the point: if every statistic voted, importing five more of one kind would quietly change what the topic is about.
- Each key is read at one edition. ⚠ The keys behind this standing do not all describe the same year — they run from 2023 to 2025, because publishers release on their own schedules. Read the standing as “how this country places now”, not as a snapshot of one year.
- Every country’s published value is turned into a place within that one key’s own field, and then expressed as a share of that field — how far down this key’s list the country sits, rather than how many countries are above it. Keys where a higher published number is worse (terrorism, hunger, disaster risk) are turned round first, so the good end is always the same end.
- Dividing by the field first is the whole reason this works. A place carries the size of its list inside it: 22nd of 44 and 108th of 215 are the same showing, and averaging the numbers 22 and 108 says loudly that they are not. Fields on this site run from about 44 countries to about 215, so averaging raw places would reward a country for happening to be measured in small ones. Dividing each place by its own field removes the size and leaves only the showing.
- The shares are averaged, plainly. One key, one vote — no key is weighted above another, because any weighting would be this site’s opinion presented as a measurement. Countries are then put in order by that average, and the average itself is never published. It is our arithmetic with nothing anchoring it, so printing it would invite it to be read as a measurement somebody made. The position it produces, the band, and the keys it was built from are all published instead — every one of them checkable against the tables on this page.
- A country needs 2 of this topic’s 4 keys — half, rounded up, and never fewer than 2. A standing built from one reading, printed beside one built from four, is two different things sharing a column heading. 198 countries clear the bar here.
- A key has to earn its vote every edition. It must measure at least 120 countries (below that it starts measuring who was surveyed rather than the world), it must not have more than 10% of its field tied at either end, and it must not repeat another key in the same topic — Spearman correlation above 0.92 counts as repeating. A topic needs at least 2 surviving keys to place anyone at all; this one has 4.
- A standing is relative, and the grouping is ours. It says where a country places against the others measured alongside it, so it moves when they move. The publishers listed on this page did not agree to be read together, and each measures its subject its own way: the underlying numbers are theirs, the ordering on top is this site’s — the same method as the rest of the Country Index, applied to one subject instead of all of them.
