The Advanced School for Girls was a South Australian State school whose purpose was to prepare girls to qualify for entry to the University of Adelaide. Founded in 1879, the school merged with Adelaide High School in 1907.

From its inception, the University of Adelaide welcomed female students, although degrees were not available to females until 1880. At first, the only schools preparing girls to matriculation level were small private colleges such as Miss Martin's School and Parliament considered that education of women should be on a more structured basis, and the "Education Act of 1875" provided for establishment of a government-funded Advanced School.^[1]

The first appointments were for a headmistress and assistant head: Jane Stanes and Edith Cook (both transferred from the Grote Street Model School),^[2] followed by Rene-Armand Martin (French). Stanes resigned the following year, ostensibly due to ill-health, and Cook was promoted to head in 1882. A Government regulation, stipulating that the head must be aged 25, had to be waived for her to be appointed, as she was only 20. The Minister of Education (Thomas King) did not approve, but his successor (J. Langdon Parsons) pushed it through.

The school, in the two-storey former residence of Dr. Lambert Butler, Franklin Street, was opened on 7 October 1879 with sixteen students passing the entrance examination.^[3] Additional appointments were made in 1880: Madeline Rees George (German), Ellen Thornber (assistant), Kate C. Brown (assistant).^[4] By September 1880 the number of students was 92.^[5] The following year, there were more applicants than places.^[6] By 1882, girls from the school were prominent in the matriculation results: two of the top nine were from the Advanced School.^[7] In 1883, both recipients of the Sir Thomas Elder prize for physiology were students of the Advanced School.^[8]

Many criticisms were leveled against the school: that it robbed educated widows of a source of income as tutors; that by conducting an entrance examination and by not conducting junior classes it had an unfair advantage over other schools; and that by offering French and German rather than the more difficult (and essential for University degrees) Latin and Greek, it was gaining an inflated reputation and at the same time robbing talented women of opportunities.^[9]

In 1891 a new purpose-built building on Grote Street was completed. The move from Franklin Street enabled the number of students to be raised from 124 to 150.^[10] This building still stands today (2016).

A.S.G. merged with the (co-educational) Adelaide High School in 1907 under headmaster W. J. Adey, later Director of Education. It took over the three adjacent buildings in Grote street which were previously (from east to west): Advanced School for Girls, Teachers' Training College, and Grote Street Model School. In 1951 the school divided into the Adelaide Boys' High School and the Adelaide Girls' High School under headmistress Mary Veta Macghey.^[11]
