In 1899, Lim Boon Keng, Song Ong Siang, Khoo Seok Wan, along with others, actively promoted a school for Chinese girls and in April 1899, SCGS was established.

[3] Due to general resistance of the local conservative population who was not in favour of girls having a formal education, transportation between the school and the students' homes has to be provided by SCGS.

The school building was a two-storey block with 12 classrooms, an assembly hall, a staff room, and a principal's office.

On 4 July 1994, after 70 years at Emerald Hill, the school moved to a newly built campus at Dunearn Road.

[9] However, SCGS would continue to offer the Singapore-Cambridge GCE Ordinary Level Programme to existing and incoming students.

All students enrolled in Eunoia Junior College will sit for the Singapore-Cambridge GCE 'A' Level examination after a two-year programme.

This symbol, which represents the universe, light, darkness, life and death, lies at the heart of the many branches of classical Chinese sciences, philosophy and medicine.
