Open Sky International

A private bilingual English-French school in Boulogne-Billancourt that grew from a nursery and primary into a full age-2-to-18 setup, with secondary added in 2017 and a high school in 2022.

Teaching is split roughly equally between English and French and the school is one of the few Pearson Edexcel exam centres in France, which means students sit IGCSE and A Level rather than the IB. Classes are small and the bilingual progression is the headline draw for families who want both languages held to a high standard rather than one as an after-thought.

The signal from families is genuinely mixed. Positive voices praise dedicated teachers, the personal attention, and how quickly children become comfortable in both languages. The recurring complaint sits around communication and transparency with management, including a policy that limits direct teacher contact between formal evenings. Visit, ask about how the upper school is settling, and probe how complaints are handled before deciding.
