It was originally named Diocesan Native Female Training School in 1860, when it was founded at Bonham Road and Eastern Street in Hong Kong Island. The School was set up by the wife of Bishop Smith. He was the first Bishop of Victoria sent by the Society for the Promotion of Female Education in the East, a sub-society of the London Missionary Society. At first, it admitted only girls. In 1866 it was renamed Diocesan Female School. Because of financial problems the School had to restrict its services solely to orphans and destitute girls in 1869. Later, it became the Diocesan Home and Orphanage and accepted boys as well.
The School first received government financial assistance in 1878 and was placed under the grant-in-aid scheme, officially establishing itself as a girls' school. The boys were to continue their education at the newly founded .
In 1913, the School finally moved to its present site in Kowloon, formerly a rice paddy field. In the 1920s, the school motto, ''Daily Giving Service'', was adopted. During the Japanese in World War II, the School was taken over as headquarters of the Japanese gendarmerie until it was re-opened in September 1945 by Ms. Gibbins, then headmistress, who was interned at during the occupation. Immediately upon her release, Gibbins hurried back to reclaim the school premises despite difficulty in crossing the harbour, thus saving the building from being looted by angry residents.
In the 1950s, with the closure of the adjacent town-gas depot, the School was able to expand. The old Edwardian edifice was pulled down, and three school blocks were constructed to accommodate the enlarged student body. The School embarked on a large scale school expansion project, and two extension blocks were opened respectively in 1993 and 1996. A new phase of expansion had been completed and was opened officially on the 12th of January, 2007.
Recently, the School celebrated its 145th Anniversary, and a musical production "The DGS Girl" was staged at the Shatin Town Hall, telling the history of DGS through the life of a group of girls: Mary Jean, Annie, Catherine, Sandra, and Jaqueline.
The school motto is "Daily Giving Service", an adaptation of which was coined by former Headmistress Dr. Joyce Symons for DGJS to be "Daily Giving Joyful Service".
DGS has joined the Direct Subsidy Scheme in 2006.
In 1976 the School handed out application forms for its Primary School together with a solicitation for a "voluntary donation of HK$1,000" towards the construction of a new Primary School building. This drew a great deal of criticism from the public and fueled the debate about the questionable recruitment practices of elite schools. Symons had responded that the solicitation had been cleared by the ICAC, and in addition that the School had sent out the solicitations "inadvertently". The School was forced to dissociate the request for donations from applications.
The controversy also contributed to demands that the Legislative Council of Hong Kong, of which Symons was the sole representative of the education sector, be made more representative of the sector.
