Trillium International School is an English–French bilingual school in Marly-le-Roi, about 30 minutes from Paris. The nursery follows Montessori pedagogy, with classes limited to 14 and an assistant in the Nursery. The preschool ages 2–4 explore the world through observation, sensory activities and hands-on learning, while Reception and Primary (ages 5–11) study the British and French curricula in a bilingual framework. The curriculum blends British and French content with Montessori-inspired methods, including a dedicated Science, Technology and Robotics Room where students engage in projects across Life and Earth Sciences, Physics and Chemistry, and Technology and Engineering. Pre-primary introduces programming with Bee-Bot, Cubetto, and ScratchJr, and Primary extends to visual coding and programmable robots such as Thymio and LEGO WeDo using iPads to diversify resources. English is taught alongside options for Chinese or Spanish. After-school care and holiday camps complement language development, sport, and cultural activities in a supportive bilingual community.
