The Haileybury campus originally belonged to, and was occupied by, the East India College (EIC), the training establishment founded in 1806 for administrators of the East India Company. The EIC was initially based at Hertford Castle, but substantial grounds in Hertford Heath were acquired for future development. William Wilkins, the architect of Downing College, Cambridge, and the National Gallery in London, was appointed principal architect. The buildings compose four ranges which enclose an area known as Quad, the second-largest academic quadrangle in Britain after Christ Church, Oxford.[6]

In 1942, Haileybury and the Imperial Service College (which had itself subsumed the United Services College) merged to become Haileybury and Imperial Service College, now referred to simply as Haileybury.[7]

In the late 20th century, reforming headmaster David Jewell took charge of Haileybury, bringing it out of its post-Cold War austerity. Stuart Westley, Master of Haileybury until July 2009, was responsible for making the school fully co-educational.[8]

Haileybury Almaty[edit]

In 2006/2007, Haileybury advised on the building of a Haileybury in Almaty, Kazakhstan where all English GCSEs are taught and the curriculum is taught similarly under the guidance of Haileybury. The school, opened in September 2008, is known as Haileybury Almaty.

The pupils are made up mostly of Kazakhstan citizens. They are all required to speak English. The academic year 2010–11 saw the first batch of pupils pass their IGCSE exams. Since August 2011, Haileybury Almaty has opened a sixth form. In 2016, 11 pupils graduated from the sixth form, with one getting admission to Trinity College, Cambridge University, and 6 securing places at University College, London (UCL). A second school, in the Kazakhstan capital, Nur-Sultan, was opened in September 2011.[9]
