Absolutely wonderful. I urge every parent to go to the Open House and see for themselves why this school is THE best in London. Delighted with every aspect of the school – and knowing that our son will grow up to be an independent, and global minded world citizen, is the greatest thing of all.Review from a Grade 7 parent
The International Baccalaureate Middle Years Programme (ages 11-16) and Diploma Programme (ages 16-19) at Halcyon provides students with rich academic opportunities for personal development through a holistic and internationally-focused curriculum, enhanced by the vibrant culture of London. The IB differs from the British education system – and other national systems – because it is more than an academic preparation for university: its core purpose is to enable young people to better understand and improve our world.
At Halcyon London International School, every student has a voice: the opportunity to lead, collaborate, and advocate for the wellbeing of everyone in our diverse, international school community. A wide range of extracurricular activities and sports, alongside Halcyon’s unique coaching, personal learning and Explorations programmes, enrich the International Baccalaureate MYP and DP programmes, nurturing every aspiration and passion.
As an international school in London, our growing community of graduates attend leading universities across the world: from Russell Group universities in the UK to American Ivy League colleges to international institutions in Europe and Asia, our students are flourishing after completing their IB Diploma. We welcome you to celebrate our wonderful student success stories and IB Diploma results with us, here.
Halcyon London International School is home to a diverse student body, ages of 11-18. Our admissions team has welcomed students from British independent schools, boarding schools, and international schools from all over the world.

Our students graduate from Halcyon with the skills to be leaders, communicators, and collaborators in an ever more complex and changing world. Our students are prepared for the digital technology revolution: the IB embeds STEM skills across the curriculum, and our Explorations and extracurricular programmes offer students the opportunity to master coding; to engage in nationwide mathematics competitions; and to compete with other international schools, independent schools, and state schools through our Vex Robotics programme.
Science Facilities at Halcyon
IB learners acquire the skills and knowledge to investigate problems in real-world contexts, and learning in central London enriches every student’s school experience. The city’s world-class universities, theatres, museums, galleries and exhibitions provide opportunities for each child to take their learning from our campus to every corner of our vibrant city. Our students could be beachcombing on the Thames to explore the past, discovering the history of natural science in South Kensington’s museums, or enhancing their language skills by enjoying Mandarin or Spanish productions in London’s best theatres.

At Halcyon, we support each student’s sporting goals while empowering learners to challenge themselves through exciting Explorations opportunities such as rock-climbing, ice skating, and horseback riding. Our football teams can enjoy competing with other international schools and independent schools at sports grounds in Paddington and Notting Hill, and in our PHE curriculum, our students engage in a variety of activities ranging from Jiu-Jitsu to gymnastics.

Halcyon in the news| Pioneering Education
Barry Mansfield explains in this international news platform how schools need to rethink wellbeing: educators can develop social and emotional skills in young people through coaching, student agency, and a sense of community – not simply pastoral care. You can read the article on the PieNews website here.
In this TV interview, our Sustainability Project Leader, Martyn Steiner, pressed the need to embed climate education into our curriculum. Martyn explained that it’s “context, not content” that we need in lessons – for example, analysing the campaigns of green charities and politics in English. You can watch a clip of Martyn’s interview by clicking here.
Halcyon London International School’s founders – parents themselves – sought to create a co-educational school in London which would empower students to navigate a complex future as leaders, communicators and risk-takers. As a community, we recognise the need to use innovative teaching methods to pioneer education and prepare our students to reach success at school through the university- and career-readying curriculum of the International Baccalaureate Diploma Programme.
