Bilingual schools in Ljubljana offer something unusual in European international education: a small, high-quality market where one of the strongest options sits inside the Slovenian state system rather than outside it. Slovenia has for years supported international programmes within public schools, which means a family arriving in Ljubljana may find an English-medium route at a fraction of what the same education would cost in Vienna, Zurich or Milan.
That makes Ljubljana worth understanding properly rather than skimming. This guide covers the language models available in 2026, how much Slovenian your child will realistically acquire, what the various routes cost, and the questions that separate a genuinely bilingual programme from a marketing line.
The language models you will encounter
- English-medium international with Slovenian as an additional language. All subjects taught and assessed in English; Slovenian appears as a timetabled subject, usually differentiated for beginners. The standard international school model and the right choice for families expecting another move.
- State-supported international programmes. Slovenian public schools that host an English-medium international stream, in some cases including the International Baccalaureate. Because they sit within the state system, costs are dramatically lower. Capacity is limited and admission criteria apply.
- Dual-language provision. Subjects genuinely split between English and Slovenian across the primary phase, producing bilingual outcomes rather than a second language as a subject.
- Slovenian curriculum with strong English teaching. Local private and public schools with intensive English. The cheapest route, and effective for families staying long term, but the working language of school life is Slovenian.
The diagnostic question is always the same: in which language is each subject assessed? If the answer is English across the board, you are looking at an English-medium school with a language subject attached. That is a perfectly good product; it is simply not the same as dual-language immersion.
Bilingual and international school options in Ljubljana
Danila Kumar International School
Danila Kumar International School is the option most families overlook and the one worth investigating first. It operates as an international department within the Slovenian public system, delivering an English-medium international programme alongside the Slovenian school. For a family that qualifies, the combination of an established international curriculum, a genuinely mixed Slovenian and international student body and state-system costs is difficult to beat anywhere in Europe. Places are finite, so contact them early and ask precisely what the admission criteria and fee structure are for your circumstances.
Ljubljana International School
Ljubljana International School is an English-medium international option in the city, with Slovenian taught as an additional language. Ask how Slovenian classes are grouped by level, because a single mixed class covering beginners and near-native speakers is where language progress usually stalls in small schools.
British International School of Ljubljana
British International School of Ljubljana delivers a British curriculum pathway in English. For families arriving from a British school or heading towards UK universities, the continuity in curriculum structure, assessment style and terminology removes a great deal of friction. Confirm which examination courses are actually running in the senior years, since cohort size limits option blocks in any city this size.
ERUDIO International School
ERUDIO International School is a further English-medium option in Ljubljana. As with every school on this list, press on accreditation status, the actual roll in the year group your child would join, teacher retention from last September, and what support exists for a child arriving with limited English.
How much Slovenian will my child actually learn?
Be realistic about this. A child in an English-medium school taking two or three periods of Slovenian a week, speaking English at home and in the playground, will finish primary school able to handle shops, greetings and street signs. That is a useful outcome and it is not fluency.
Three things move the needle. First, a school with levelled Slovenian groups rather than one mixed class. Second, at least four periods a week. Third, and most important, structured exposure outside school. Ljubljana is small, safe and unusually well provided with municipal sports clubs, music schools and youth programmes, all of which run in Slovenian. A child who joins a local football, handball or skiing club will make more progress in a term than in two years of classroom instruction.
One planning point: if there is any chance your child will transfer into the Slovenian state system, ask now what that transition would require. Slovenian-medium subject content at secondary level is difficult to pick up cold, and the schools that handle these transfers regularly will tell you honestly what is involved.
Fees in Ljubljana
Slovenia uses the euro. Indicative annual ranges for 2026:
- State-supported international programmes: from a few hundred to a few thousand euros a year, depending on eligibility and programme. This is the reason to investigate them first.
- Private international, early years: EUR 5,000 to EUR 11,000
- Private international, primary: EUR 7,000 to EUR 14,000
- Private international, lower secondary: EUR 9,000 to EUR 17,000
- Private international, diploma years: EUR 11,000 to EUR 20,000
On top of tuition, budget for a one-off registration fee, lunch, after-school activities, trips, devices and external examination entries in the senior years. Ten to fifteen per cent on top of tuition is a sound planning figure. By European standards Ljubljana is inexpensive, and the state-supported route makes it exceptionally so for families who qualify.
Where families live
Ljubljana is genuinely small, which is one of its pleasures. Families settle in Bežigrad and Šiška for apartments with good transport, in Vič and Rožna Dolina for proximity to green space and the university quarter, and in Trnovo and Rudnik for houses with gardens. Almost nowhere in the city is more than 20 minutes from anywhere else, cycling is practical for much of the year, and the school run is not the ordeal it becomes in larger capitals. Winter fog in the Ljubljana basin and snow on the approach roads are the main seasonal complications.
Questions to ask on every visit
- In which language is each subject taught, and in which language is it assessed?
- How are Slovenian classes grouped by level, and how many periods a week?
- Am I eligible for a state-supported international programme, and what would it cost?
- What support exists for a child arriving with no English, and what is the charge?
- What is the real roll in the year group my child would join?
- What proportion of teachers returned from last academic year?

Frequently asked questions
Are there bilingual schools in Ljubljana?
Yes. Ljubljana offers English-medium international schools with Slovenian as an additional language, dual-language provision at some schools, Slovenian-curriculum schools with intensive English, and international programmes hosted within the Slovenian public system. Ask in which language each subject is assessed to distinguish genuine dual-language teaching from an English-medium school with a language subject.
How much do international schools in Ljubljana cost in 2026?
Private international schools typically charge EUR 5,000 to EUR 11,000 a year for early years, EUR 7,000 to EUR 14,000 for primary and EUR 11,000 to EUR 20,000 for the diploma years. International programmes within the Slovenian state system cost dramatically less, sometimes only a few hundred to a few thousand euros, if your family is eligible. Add 10 to 15 per cent for registration, lunch, activities and examination fees.
Will my child learn Slovenian at an international school?
Most international schools in Ljubljana teach Slovenian as an additional language, usually two to four periods a week. That produces functional everyday competence rather than fluency. Real progress comes from levelled classes, four or more periods a week, and joining a local sports or music club where Slovenian is the working language.
