Sydney Technical High School (STHS) is a government-funded single-sex academically selective secondary day school for boys, located in Bexley, a southern suburb of Sydney, New South Wales, Australia. Founded in 1911 as part of Sydney Technical College, the school was one of the six original New South Wales selective schools and caters for boys from Year 7 to Year 12. The school is colloquially abbreviated to Sydney Tech, STHS or simply Tech. Admission to Year 7 is based on an external selective test held in Year 6 during March. Admissions for new students to Years 8, 9, 10 and 11 are restricted to filling any vacant places created by the loss of current students. Academic achievement The school consistently achieves superior results in external assessments, such as the NAPLAN, the ICAS, the Record of School Achievement, and in particular, the Year 12 Higher School Certificate (HSC), where its students are regularly ranked in the top ten places in the state across a variety of subjects. On average, over 80% of its students achieve in the top 20% of the state, with a majority gaining an Australian Tertiary Admission Rank of more than 90. In 2010 fifteen students from the school's graduating class received Premier's Awards for All-round Excellence in the NSW HSC. The school won the national championship in the University of Newcastle Science and Engineering Challenge in 2010 (gold division) and 2011 (silver division). History One of the reforms advocated by the 1903 Royal Commission into NSW Education was the establishment of classes providing courses which would involve technical subjects. Consequently, Continuation classes for students interested in technical subjects commenced at the Sydney Technical College. In April 1911, these Continuation classes were given the status of a high school, and Sydney Technical High was established. Originally, the school was co-educational with 113 boys and 15 girls. In February 1913, the girls were transferred to Fort Street Girls' High; and, from then on, the school became for boys only. Since 1911, the school has been located at three Sydney sites: Ultimo House on Mary Ann Street: this was the "country" home of John Harris, Surgeon of the New South Wales Corps. The property was bought by the Government in 1899 and used by Technical Education for many years before being used by Sydney Tech High from 1911 to 1924.
