In this year a post primary vocational educational course of two years duration for non academic students was established and Wollongong Public School offered it in the Domestic Sciences. The course offered tuition and training in Household Accounts, History and Geography, Cookery, Laundry, Dressmaking, Home Management, Hygiene, Infant Care, Botany, Morals, Music and P.D.H.P.E

In 1911, the Secondary courses were reconstructed with students sitting for the Intermediate Certificate after two years and then the Leaving Certificate after another two years study. Students of Domestic Sciences were not eligible to sit for these examinations. Five years later in 1916, the present A block was constructed and named Wollongong High School. It was not until 1957 that the Wollongong Home Science School, as it was known, was relocated from the Smith Street School. At this time Wollongong High School moved to its present site and in 1958 Smith's Hill Girls High School came into existence. It was decided that girls studying Domestic Science could sit for the Intermediate and Leaving Certificates.

During the 1970's plans were underway to change SHGHS into a comprehensive, co-educational High School and in 1979 the school was renamed Smith's Hill High School. In 1985, boys were enrolled in Years 7,8,9 and 11 drawing from feeder schools at Wollongong, Coniston and Mt St Thomas. By 1986, SHHS was co-educational from Years 7-12.

The most recent and dramatic change was in 1988 when the NSW Department of School Education decided that SHHS would become a Selective High School as from the Year 7 intake in 1989. In more recent years entry into SHHS has become considerably more competitive and students travel from as far afield as Nowra, Helensburgh and the Highlands to attend the school.
