- This Hertfordshire school opened a state-of-the-art science and technology centre in 2024 that houses pioneering research projects including the Stan-X genetics initiative and enables pupils to collaborate with scientists from Stanford and Oxford universities.
- Haileybury has committed to a sustainable future by pledging to be carbon neutral and energy self-sufficient by 2030.
- Extracurricular activities range from professional sports coaching, drama, music, dance, and art to regular expert-led talks in these fields. Pupils can also build confidence through the Combined Cadet Force, the Duke of Edinburgh’s Award and the school’s adventure skills programmes, which include activities such as climbing, scuba diving, film-making and the Model United Nations.
- House leaders, tutors and the chaplain offer round-the-clock support to students and there is an onsite health centre alongside a wellbeing space — a quiet area with its own kitchen and garden. The school has a strict policy on mobile phones to ensure pupils sleep properly at night.
- Scholarships in academics, music, sport, drama, art and design technology are awarded on merit and include a fee remission. Means-tested bursaries are also available for talented candidates or those with significant pastoral needs, whose families would otherwise be unable to afford the fees.
