LONDON, 3 November 2026. Halcyon London International School will hold an in-person Open House with a guided tour on Friday 13 November, from 9:45 am to 11:45 am, at its campus at 33 Seymour Place in London. The school teaches students in Grades 6 to 12, aged 11 to 18, through the International Baccalaureate.
The Open House is a guided tour for families considering a place at Halcyon, with entry open from Grade 6 up to Grade 12. It gives parents and children the chance to see the school in person before choosing a school for the coming years.
Halcyon is a co-educational International Baccalaureate school for Grade 6 to 12 students, equivalent to Year 7 to 13, in West London. It is a not-for-profit school with small class sizes. Fees include an in-house cooked lunch and an annual one-week residential trip, and Halcyon is a bring-your-own-device school.
In October, the school reported that every student passed the 2026 IB Diploma and that 95% of the class scored 30 points or more. Fifteen graduates went on to universities in the UK, Europe and the US, including UCL, KCL, Sciences Po and Pepperdine University, and two students from the Class of 2026 joined the workforce directly, one of them in a data science degree apprenticeship at Bloomberg.
