Aix-area families do not have to choose between “international” and “French” as if those were opposites. IBS of Provence and Lycée International Georges Duby offer different combinations of languages and qualifications.
Start with age and curriculum
IBS is a private bilingual school at Domaine des Pins, 500 Route de Bouc-Bel-Air, in Luynes. It welcomes day pupils from age two and boarders from 6ème. Later options include the French baccalaureate and the IB Diploma. It is the more relevant choice if you need younger years, boarding before lycée or an IB route. Ask which subjects are taught in each language at the proposed entry point.
Georges Duby is a public lycée at 200 rue Georges Duby, in the Rampelin area. It starts at Seconde and offers a British international route towards the Baccalauréat Français International, alongside Abibac. The latter combines the French baccalaureate and German Abitur. This is a French-curriculum option for a pupil with the appropriate language preparation, not an English-only school.
Do not assume boarding means the same package
Both schools have boarding provision. IBS publishes separate day, weekly-boarding and full-boarding fees for 2026–27. Check which meals, activities, examination charges and holiday arrangements are included in your chosen package.
For Duby, confirm boarding admission and costs separately from academic admission. A public lycée place does not automatically provide an internat place, and public education does not make meals and accommodation free.
Use the next application calendar
Duby’s advertised open day on 1 April 2026 has passed. Ask for the next section-specific application dates and how selection fits the public allocation process. At IBS, request the assessment and language-support requirements for your child’s year, not only a campus tour.
Test the journey to each actual address from your likely home. For a younger child who could join French education, also examine the local public primary or collège and its newcomer support.

Friendly orientation, not formal admissions advice. Always confirm dates with the school.
