Director's Message

Welcome to Halcyon London International School.

Halcyon is guided by a clear mission – to provide an exceptional education that draws out the unique potential of each student – and is built upon three pillars: innovation, collaboration and community. We embrace change and challenge, strive collaboratively and individually for fulfilment, and support and respect each other. We are constantly looking for new approaches, each with a clear and purposeful impact on the quality and efficacy of learning for everyone in the community. I am proud to be leading a talented and dedicated group of teachers, who share the understanding that learning is a social and collaborative endeavour, and that our role is to provide students with the agency to be self-directed, creative, and independent. Student wellbeing – a sense of having a place, an identity and a purpose in our learning community – underpins successful learning, and this is a central part of everyone’s learning journey at our school.

We are an International Baccalaureate (IB) World School. Not only does the IB provide a widely-respected university entrance qualification, but it also offers a framework that allows every child the opportunity to fulfil their unique potential. While providing the challenging, academic IB Diploma programme in Grades 11 and 12, Halcyon provides personal learning time, ‘Exploration’ learning, and individual mentoring for all students.

Halcyon is not-for-profit and forward-thinking. We ask how our understandings about the World change, and how that might be made real in the classroom. We are purposefully and thoughtfully a digital school, and we foster life-long learning skills such as teamwork and collaborative problem-solving, an outward international outlook, and a sense of wonder and joy in discovery. This, in turn, enables students to be self-directed, independent and intellectually curious – habits of mind that will support them far beyond the classroom. We seek to provide a life-readying education and to do so in a collaborative, caring, and open community.

If you would like to be a part of a vibrant, innovative educational community in the heart of London, please do visit our school and enjoy the unique Halcyon experience.

Kind regards,

Barry Mansfield, Director

Our Mission

To provide an exceptional education that draws out the unique potential of each student.


The Halcyon community emboldens and supports every learner to be an explorer, a risk-taker and a creative problem-solver. We embrace challenging questions and seek out purposeful, research-led answers.

To build this creative, curious and questioning culture, Halcyon’s IB curriculum is designed to promote self-directed learning and critical thinking. Our work is enriched by pioneering digital resources, fully integrated into our school practice.


Collaboration is at the core of our community of life-long learners. Learning together we build different perspectives as we understand ourselves in relation to others. This experience allows each of us to navigate the world successfully and shape who we want to be.

We intentionally create an environment that develops and encourages collaborative learning and teaching through the promotion of trust, mutual respect, and shared values and leadership.

Collaboration is present in our leadership approach, our learning spaces, our staff workshops, our coaching dialogue, and through the passion of student initiative and engagement.  Collaborative practice is supported by our pioneering wellbeing programme and our emphasis on restorative practice and fostering ownership, agency, voice, and belonging.


Halcyon understands that successful communities learn and create together, supported by a culture of shared values.

We are committed to creating an inclusive community that appreciates and respects each person. All are welcomed to contribute and develop a sense of agency and ownership of the school and its mission. Just as we wish all students to fulfil their unique potential, we actively nurture the same opportunities for growth for everyone in our community.

We also commit to participating in the wider community through service-learning and engaging constructively with wider social challenges.
