Glenunga International High School is a publicly funded school in Adelaide, South Australia. It is located approximately four km south-east of the Adelaide city centre in the suburb of Glenunga, between L'Estrange St and Conyngham St, adjoining the major thoroughfare Glen Osmond Road. In terms of academic performance, it is one of the top schools in the state, performing exceptionally in the NAPLAN, SACE, and International Baccalaureate Diploma. The school serves the surrounding suburbs of the cities of Unley, Burnside and the Adelaide Hills. It was the first public school in South Australia to offer the International Baccalaureate Diploma Programme.PrincipalThe current principal is Wendy Johnson, who commenced her term at the beginning of 2008. She was previously the principal of Victor Harbor High School and has experience as a teacher, administrator and district director.Robert Knight, who started at the school in 1992, retired as principal at the end of 2007. He helped improve the standing of the school with features such as a large international student program (under the Intensive Secondary English Course) involving many students from China, Japan and a variety of south-east Asian nations; a selective program for gifted students entering high school (Ignite Programme, initiated as the SHIP program in 1998) and the adoption of both the local SACE and International Baccalaureate Diploma Programs. Knight's term saw enrolment increase by 700 students to 1400 (many of whom are from areas outside the school's zone, or from overseas), after it came close to being closed by the State Government in the mid-1990s due to falling enrolments.
