From preschool to high school, one campus and one curriculum: English and French every day, programmes built on the British, Singaporean and French curricula, and qualifications recognised worldwide, GCSEs/IGCSEs followed by A Levels and the bilingual French-English IB Diploma Programme (IBDP).
Open Sky International's bilingual curriculum covers a child's entire schooling, from ages 2 to 18, on our campus in Boulogne-Billancourt. Each stage of the curriculum (preschool, primary, middle school, high school) has its own teachers, classes and objectives, but one shared principle: English and French are the two languages of instruction, every day, taught by native-speaker teachers.
Our programmes are designed by the school, drawing on the British (English National Curriculum), Singaporean (maths) and French curricula. They lead to GCSEs and IGCSEs in Year 11, then to A Levels and the IBDP in Sixth Form, at our accredited Pearson Edexcel examination centre. A child who joins in preschool follows the same curriculum through to the end of high school, without changing school or method.
Both languages are present at every stage of the bilingual curriculum, and their role changes with age. In preschool, English and French are learnt through games, songs and routines, with adults who speak only their own language. In primary, each language becomes the language of instruction for some of the subjects, and reading is learnt in both, each with its own method. In middle school, the split of subjects between the two languages settles and a third language, Spanish, is added in Year 9 (4e). In high school, exams set the framework of the curriculum: GCSEs/IGCSEs, then A Levels, with French maintained right to the end.
Beyond English, French and Spanish, the curriculum offers optional intensive classes in languages spoken at home, such as Hindi, Mandarin, Japanese, Arabic or Russian.
The table places each year group of our curriculum, from ages 2 to 18, within the French, British and American systems.

The preschool curriculum covers communication and language in both languages, physical, personal, social and emotional development, understanding the world, art, music and early phonics in English. By the end of Reception (MS), our pupils can read and write simple texts in English. They can solve simple addition and subtraction problems.
The primary curriculum covers reading and writing in both languages (phonics in English), maths using the Singapore method (Singapore maths), science, history and geography, art and sport. English, maths and science are taught in English. French and understanding the world are taught in French. The languages are split by day: for example, Mondays in French, Tuesdays in English, and so on.
The middle school curriculum teaches French, history and geography in French, and maths, science and English in English; Spanish is added from Year 9 (4e), along with Business Studies in English. The GCSE/IGCSE cycle begins in Year 10 (3e). Students no longer alternate between a French day and an English day. They switch from one language to the other within the same day, according to their timetable.
The high school curriculum prepares students for GCSEs and IGCSEs in Year 11, then for three to five A Level subjects in Sixth Form, including French, with university guidance. From September 2027, students will also be able to choose the bilingual French-English IBDP.

Two milestones structure the bilingual curriculum. In Year 11, students sit GCSEs and IGCSEs in 9 subjects at the school. In Sixth Form, A Levels cover three to five subjects studied in depth, including French.
A Levels are recognised by universities worldwide and give access to French higher education. Both are awarded by Pearson Edexcel, for which Open Sky International has been an accredited examination centre since 2022.
The bilingual curriculum is designed to welcome a child at any age, from preschool to Sixth Form, whether they come from the French system, an international school or from abroad. The entry assessment determines their class and language pathway; EAL (English as an Additional Language) or FAL (French as an Additional Language) support closes the gap in the language they have not yet mastered.
In high school, students join in Year 10 (3e) to follow the two-year GCSE/IGCSE cycle, or in Year 12 (1re) for the two years of Sixth Form. As Year 12 and Year 13 are exam years, admission to these years is considered case by case, and fluent English is required.
No: Open Sky International is an independent international school that designs its programmes drawing on the British, Singaporean and French curricula. The school takes inspiration from the best practice worldwide and, where it cannot find it, designs its own curriculum. Our students far exceed the expectations of the French core curriculum (socle commun), which the rectorat (the regional education authority) regularly inspects. They prepare for the British GCSE and IGCSE qualifications, followed by A Levels and the IBDP.
It corresponds to 6e (ages 11-12) in our curriculum. The table above gives every equivalent, from TPS to terminale.
Yes. They are of course able to join the French system later, often 1 or 2 years ahead.
The curriculum leads to GCSEs and IGCSEs in Year 11, then to A Levels and International A Levels in Year 13, recognised by universities worldwide. From September 2027, students will be able to prepare for the bilingual French-English IBDP.
The bilingual IBDP will be offered from September 2027.
