Sydney Boys High School ("SBHS"), otherwise known as The Sydney High School ("SHS") or High, is a government-funded single-sex academically selective secondary day school for boys, located at Moore Park, New South Wales, a suburb within the City of Sydney council, in Sydney, New South Wales, Australia.
Established in 1883 and operated by the New South Wales Department of Education, as a school within the Port Jackson Education Area of the Sydney Region, the school has approximately 1,200 students from Year 7 to Year 12 — a number greater than most, if not all, other selective state schools — and is situated adjacent to its "sister school", Sydney Girls' High School. The school is a member of the Athletic Association of the Great Public Schools of New South Wales (AAGPS). Sydney Boys High School is an academically selective high school conducted by the NSW Department of Education.
The school was moved to its current site at Moore Park in 1928. The school is bounded by Moore Park, Anzac Parade, Sydney Girls High School and Cleveland Street.
The school regularly ranks highly among schools in New South Wales in terms of academic achievement, ranking 5th in the state in the 2017 Higher School Certificate, and has produced numerous notable alumni, or "Old Boys".
Although Fort Street High School was established as an elementary school in 1849, Sydney Boys High School was the first state high school in New South Wales and Australia. It was created under Premier Henry Parkes' public education system in the early 1880s, following the Public Instruction Act 1880 (NSW). Whereas Fort Street Model School as it was founded took primary and secondary students neither Sydney Boys nor Sydney Girls High School has ever had a primary education division and are thus the first NSW state high schools founded for the express purpose of secondary education.
Alternatively known as The Sydney High School, due to its being the first state high school, Sydney High School was established as two single-sex schools sharing a single building, with boys and girls on separate floors.
