At Caringbah High, language is compulsory in years 7 and 8 and it is taught as an elective for years 9-12. Languages taught include French, Japanese, and Latin, and prior to 2020 the school also taught German. As of 2020, the protocol is that year 7 students rotate between the three languages, and in year 8, each student picks one language that they favour most, which is studied for the whole year. Once in year 9, students have the option of continuing study in the language that they have chosen as an elective.
