Admissions
Admissions at Halcyon London International School are welcoming but carefully judged, particularly for internationally minded families seeking an IB pathway in central London. The emphasis is on curiosity, fit and readiness for a questioning academic culture rather than on a single narrow idea of selectivity.
Scholarships
