Welcome to Primary Years

Welcome to the International School of London Primary Years Programme.

ISL is an international school well into its fifth decade of excellence in education. Situated in the leafy environs of Gunnersbury Park, West London, we offer the International Baccalaureate Primary Years Programme (PYP) - a developmental, inquiry-based programme that guides students through learning based on real-life experiences.


Active Learning

ISL learning does not just take place in the classroom.  The PYP is designed to provide opportunities for students to engage with the world in a ‘hands-on’ and interactive manner, encouraging an active learning approach.

Through programmes such as our Classroom Without Walls, Forest School, and our Units of Inquiry, students delve into real life issues and apply their skills and knowledge in meaningful ways. 

The PYP balances acquiring essential knowledge and skills with developing conceptual understanding, positive attitudes and responsible action.

Grade 5 Student learning in the classroom


At ISL, we are committed to offering students ages 3-11 a high-quality learning experience that provides them with the opportunity to explore their passions, develop their own questions and to be challenged in their thinking. Our inquiry-based approach to learning allows students to pursue their curiosity and to build their knowledge, skills and conceptual understanding.

We understand that by cultivating students’ social, emotional, and academic well-being, we nurture individuals who can see the world with compassion. Through this awareness, we as a community, can see ourselves as capable of taking responsible actions for a better world. In this journey, our students become confident, caring, internationally-minded communicators and lifelong learners.
