Trillium International School is a bilingual international school located in Marly-le-Roi, just outside Paris. We welcome around sixty students in a warm, inclusive, and supportive environment where every child is seen, encouraged, and guided.
Our vision is grounded in both academic excellence and inclusion. We offer a unique bilingual programme that blends the strengths of the British and French educational systems. This approach allows students to develop strong linguistic, cognitive, and intercultural skills while reaching high academic standards.
We are proud that many of our students are accepted into international and bilingual tracks at well-regarded secondary schools, where they continue to thrive both academically and personally.
At Trillium, we embrace diversity and adapt our teaching to each student’s needs, strengths, and aspirations. Our child-centered pedagogy promotes creativity, independence, critical thinking, and collaboration—essential skills in today’s changing world.
We are committed to nurturing confident, responsible, and engaged global citizens. Trillium is a small school with a big vision, where inclusion and excellence go hand in hand.

| Teaching approach of the school |
Same as above |
We believe that every child is unique and special in their own way. To respect your child's development, we chose the Montessori method because we believe it offers incredible benefits in every aspect. Our goal is to follow your child's learning style and adapt the program to their needs.
Class sizes are limited to 14 students to ensure the best learning experience. The Nursery class has a full-time assistant in addition to the teacher.
All our nursery and kindergarten classes follow the Montessori teaching approch.
The Trillium International School curriculum is based on the British and French national curriculum.
Our primary classes provide an ideal setting for a high level of academic achievement thanks to small class sizes (maximum 12 students) and personalized instruction.
The educational program is based on the British National Curriculum, adapted to the local community. French is taught as a core component of our academic program, from Kindergarten to Year 6. There are two to four half-day classes taught by French teachers, depending on the level, to ensure a solid foundation in French and mathematics.
Located in the heart of Marly-le-Roi, just outside Paris, Trillium International School offers a unique setting where nature, history, and learning come together. Our school is set in a green and peaceful environment, close to the town of Saint-Germain-en-Laye, the Châteaux of Marly, and the Château de Montecristo, once home to Alexandre Dumas.
Our small-scale campus reflects the values we hold dear: community and inspiration. Trillium was born from a simple vision — to create a nurturing and stimulating space where every child can thrive.
Our school provides students with an environment that supports intellectual, emotional, and social development. Trillium is a place where children feel confident, valued, and truly at home.
Trillium International School is delighted that you are considering our school for your child’s education. We would be happy to support you throughout the admissions process.
We look forward to answering all your questions and welcoming your family into the Trillium community!
