In May 2007, it was awarded Specialist Status in Languages[3] and in March 2012, it has been recognised as one of only six post-primary schools in Northern Ireland to be in the top 10% for performance at both GCSE and A-level.[4]
The institution now known as Belfast High School opened in 1854. In 1874, it moved to new premises at Glenravel Street, Belfast.
Since the school was founded, there have been 7 head teachers:
(1854–1867) John Pyper, who established the school as Pyper Academy, before changing its name to the Belfast Mercantile Academy shortly thereafter.
(1867–1917) James Pyper, the school's longest-serving headmaster. He was responsible for the building of what the Ulster Star described as "Mr Pyper's splendid new seminary"[5] in Glenravel Street.
(1917–1937) Spring Pyper
(1938–1966) Dr Robert Harte, who changed the school's name to its current title. Under his headship the school purchased Ardilea House, a large 19th-century villa in Jordanstown, in 1953. Between then and 1963, when the entire school re-located from Glenravel Street, its then Vice-Principal, Harry Towell, headed a small suburban campus at the site. The house now forms the administration block, containing the staff room, sick bay, and offices of the principal, her secretary, the bursar and vice-principal. Dr Harte suffered a severe stroke in 1964 and his son acted as temporary head until the appointment of Mr Dunlop in 1966. Dr Harte was a Doctor of Philosophy and an eminent classical scholar.
(1966–1987) Samuel H Dunlop, who saw the building of a new science block (1970), the closure of Somerton House (the school's preparatory department) in 1981 and the enlargement of the school library (1980s)
(1987–2006) Stephen R Hilditch, who saw the Harte Building opened in the 1990s to house Home Economics, Careers, Technology, ICT and a science lab, the refurbishment of the science block (2001–2003) and the refurbishment and enlargement of the Music Department
(2006–2018) Lynn F Gormley, who saw the installation of a state-of-the-art sports and fitness building which was opened by Dame Mary Peters in 2016.
(2018–present) Charlotte Weir, who had previously served as Acting Head Teacher and Deputy Head Teacher.
The school has a house system. The tie a pupil wears is blue with a thick yellow band pattern, and a thinner band pattern of an additional colour representing the pupil's house.
