Every working morning, more than two hundred thousand people cross into the Grand Duchy from Arlon, Thionville, Trier, and the towns around them — one of the densest cross-border labour markets on earth, spread across three legal systems that happen to disagree profoundly about home education. Frontalier families frequently assume that because they work in Luxembourg, Luxembourg’s rules apply to their children. They do not. Education law follows residence, not workplace, and getting that wrong is the single most consequential mistake a cross-border family can make about schooling. This article sets out the three frameworks and where an international online track fits on each side.
The rule that governs everything: residence, not workplace
A parent employed in Kirchberg but living in Trier is subject to German education law for their children. Living near Thionville places the family under French law; living around Arlon, under Belgian law. Luxembourg’s obligation scolaire applies to children resident in Luxembourg — that is the trigger, and a Luxembourg payslip does not change it. Where exactly the residency line falls for a particular household — registration, habitual residence, family circumstances — is a legal question about that household, and it belongs with the family’s own advisers. What we can do is state the three frameworks accurately and plan the education around whichever one applies.
Germany: home education is not permitted
The German side is the clearest and the strictest. Germany does not permit home education as a parental choice — school attendance is compulsory, the position has been repeatedly upheld, and no online school changes it. For frontalier families resident in Trier, Perl, Saarburg, or across the Saarland border, the only lawful configuration is supplementary: the German school carries the enrolment and the legal obligation, and an international track runs alongside it in the after-school hours. That is exactly how we work with those families — Cambridge Mathematics, sciences, and English toward IGCSE, then A-Levels in the senior years, sat as external candidates.
France: authorisation, and it has tightened
France permits instruction dans la famille, but as an authorisation regime that has tightened considerably in recent years — permission is granted case by case on defined grounds rather than assumed on request, and refusals are real. Families around Thionville, Yutz, and Metz should treat it as a genuine application process with its own criteria, decided by the French authorities and not by any school. The supplementary configuration remains the clean default here too: the French school carries the obligation, and the Cambridge or IB track runs beside it.
Belgium: its own framework again
Belgium runs its own home education rules, and they differ by community as well — another reminder that "cross-border" in this region means genuinely different law a few kilometres apart. Families around Arlon, Athus, Aubange, and Messancy should take their position from Belgian sources rather than from Luxembourg ones, and we again run supplementary alongside the local enrolment as the default. Across all three countries the practical shape of what we deliver is identical: live small-group teaching after the school day, external Cambridge or Edexcel examinations, and records the family keeps.
The move that many frontalier families eventually make
A great many cross-border households move into Luxembourg eventually, when housing, schooling, or seniority makes it work. That transition changes the legal framework entirely — the Luxembourg obligation scolaire applies from the point of residence, with home education requiring prior ministerial authorisation under the 2023 law and the framework currently under reform. What does not change is the child’s education: the same live curriculum, the same teachers, the same examination board, across a move that alters almost everything else about a family’s life. In a region where people routinely change country without changing job, that continuity is the practical case for an international pathway, and it is why frontalier families are among the most natural fits we have anywhere in Europe.
Frequently Asked Questions
We work in Luxembourg but live in France — whose education law applies?+
France’s, because education law follows residence rather than workplace. The same principle puts German-resident families under German law, which does not permit home education, and Belgian-resident families under Belgium’s framework. Where the residency line sits for your household is a question for your own advisers.
Can our child study Cambridge alongside a French, Belgian, or German school?+
Yes — that is the configuration we run on every side of the border: the local school carries the enrolment and the legal obligation while Smartious teaches Cambridge or IB subjects live in the after-school slot, toward external examinations at authorised centres in the region.
What changes if we move into Luxembourg?+
The Luxembourg framework applies from that point: obligation scolaire to sixteen, with home education requiring prior ministerial authorisation and the law currently being reformed. The curriculum, teachers, and examination board continue unchanged.
Where would our child sit examinations?+
At authorised centres in Luxembourg, Belgium, France, or Germany — whichever is most practical — confirmed per family per session.
