Admission toute l’année selon les places
Open Sky International is a private bilingual school in Boulogne-Billancourt, in the Hauts-de-Seine, welcoming children aged 2 to 18.
As an independent international school, it provides daily teaching in English and French with native-speaking teachers, and prepares students for GCSEs, IGCSEs and A Levels at its own examination centre. Our families live in Boulogne-Billancourt, neighbouring towns and western Paris. They come from more than 40 countries, and approximately 30% are French.
There are no selective entrance requirements: admissions are open throughout the year, subject to availability.
Boulogne-Billancourt is the largest municipality in the Hauts-de-Seine and one of the most international areas in western Paris, home to corporate headquarters, expatriate families and just minutes from the 16th arrondissement.
For families, this means a school just 5 minutes from Paris without the constraints of the city centre, with a campus of over 3,000 m² housing the primary school, secondary level and high school. Children benefit from outdoor patios for their breaks, a theatre room, a canteen and several activity rooms.
Many of our students walk home, meet up on Wednesdays and grow up together, from ages 2 to 18, on the same campus.
Since 2022, the school has been an accredited Pearson Edexcel examination centre, one of the few schools in France to hold this accreditation. Year 11 students (Seconde) sit their GCSEs and IGCSEs, while Year 13 students (Terminale) take their A Levels, directly at the rue Castéja campus, in their own classrooms.
A Levels are recognised by universities worldwide and provide access to French higher education.
