The "Option Internationale du Baccalauréat" (OIB) offers advanced level studies in English.

[citation needed] FIS was established in 1963, as French engineers and technicians arrived in Hong Kong to build the Shek Pik dam.

[4] Prior to 1988, the English medium stream only went up to the fifth form, with the General Certificate of Secondary Education being the end qualification.

[5] In 1988, FIS became the first international school in Hong Kong to be awarded the World IB status.

[1] The IB curriculum became available to the English medium stream and lengthened the course of study available to sixth form-equivalent students.

[7] In March 1999,[8] the newly constructed Blue Pool Road Secondary School campus was opened.

[9] As of 1990, language courses include French, English, Mandarin Chinese, Spanish, and German.

[13] The Tseung Kwan O campus houses early years through junior high school (collège).

[14] Previously the Hung Hom Campus housed primary school students; it opened in September 2014,[15] and was in Kowloon City District.

[16] The school once operated a Kindergarten campus in Shops 2–4 on the ground floor of Tung Fai Gardens (東暉花園) in Sheung Wan.
