Curriculum and academics
Halcyon is a pure secondary IB school, which sets it apart from the all through internationals. It teaches only the International Baccalaureate, the Middle Years Programme from age 11 and the IB Diploma in the sixth form, and it is the only not for profit IB World School in London. The not for profit status means surpluses are reinvested in teaching and facilities rather than distributed, which the school presents as central to its character.
Class sizes are deliberately small, averaging only a handful of students, which allows close attention and a wide subject and language offer relative to the schools size. A mother tongue programme supports first languages including Spanish, French, German, Italian, Japanese, Arabic, Hebrew, Norwegian, Portuguese, Dutch and Swedish, reflecting a community of more than sixty nationalities. Halcyon appears in our guide to the best international schools in London as a distinctive small, central IB option for internationally mobile teenagers.

Admissions
Entry is most common at the start of the Middle Years Programme and at sixth form for the IB Diploma, but the school reviews applications through the year and can offer mid year places where space allows. Admission considers prior school reports, any English language evidence for overseas applicants, and an interview, with the school looking for students who will thrive in an inquiry led IB environment rather than setting a single competitive examination.
Apply several months ahead for September entry, particularly for the Diploma, where subject choices are discussed as part of admission so that the right combination is confirmed for year 12. Relocating families benefit from the rolling review when timing a move to London.

It suits families living in Marylebone, Fitzrovia, Mayfair, St Johns Wood and the wider central core who want a small, internationally minded secondary school within easy reach.
