Luxembourg's Plurilingual School System Adds a Compulsory Luxembourgish Course

Education in Luxembourg starts in three languages and stays that way. Pre-school is in Luxembourgish, primary school in German, and French is layered in from primary onwards. By secondary level, students are expected to be functional in all three, with English added as a fourth. It is the most distinctive school system in Western Europe — and, since the 2021/22 academic year, it has added a deliberate component on Luxembourgish identity that continues to shape how the country thinks about its national language.

The compulsory Luxembourgish course

Since the start of 2021/22, students in 4e — the equivalent of ninth grade in classical and general secondary education — take a Luxembourgish language and culture course. The curriculum is built around three components: Luxembourgish language (grammar, written and oral practice, comprehension), general knowledge of the country (institutions, geography, economy), and Luxembourgish society and culture (literature, music, traditions, contemporary life). The course is not just a language refresher — it is closer to a structured civic-cultural orientation that uses language as the entry point.

The 2026 effect is that an entire generation of Luxembourg secondary-school students has now passed through a system that gives Luxembourgish formal academic standing rather than treating it as the language of pre-school instruction and then moving on.

The structural picture

Luxembourg is a trilingual country at the level of constitutional design. Luxembourgish is the national language. French is the legislative language — laws are written and published in French. French, German and Luxembourgish are all administrative and judicial languages. The school system's plurilingualism reflects that constitutional architecture, but it has had to adjust as the country's population has shifted: roughly half of residents are foreign-born, and a substantial share of school-age children arrive without prior exposure to Luxembourgish or German.

The system absorbs that diversity through bridge classes, language-support resources, and, in recent years, dedicated reception programmes for Ukrainian and other refugee children. The plurilingual model is not a casual achievement — it is sustained by a school system that allocates significant time to language acquisition, a teacher corps trained for it, and a pragmatic acceptance that no two students will arrive with identical linguistic equipment.

Higher education and the language question

At university level, the plurilingualism becomes a competitive feature. The University of Luxembourg requires undergraduates to be functional in at least two of English, French and German for most programmes. Many master's programmes are offered in English, with parallel French or German tracks. For international students, that combination — small country, world-class subject expertise in pockets, multilingual academic environment — is part of the reason the institution punches above its weight in interdisciplinary rankings.

The 2026 horizon

Two policy questions sit on the horizon. First, whether the compulsory Luxembourgish course extends downward (to earlier years) or upward (to later years), which would deepen the cultural-orientation function. Second, how the system handles the rising number of school-age children whose home language is none of the three official ones, with Portuguese, English, Italian and Spanish all common in residents' homes.

Luxembourg's plurilingual system is not perfect — drop-out rates and the social gradient of academic outcomes both reflect the cognitive cost of multi-language schooling — but it is one of the more interesting working answers to how a small country preserves its language while opening itself to a multilingual labour market.
