CIS takes pride in its innovative approach to the teaching of the Primary curriculum in English and Chinese (Mandarin), implemented from 2004. This approach involves a variety of collaborative teacher partnerships, which ensure that students receive close teacher attention while also experiencing the two languages actively used in a balanced and integrated way.
Every homeroom is headed by a pair of teachers with native-language abilities in English and Chinese (Mandarin), and at every year level teachers of the two languages collaborate to plan and teach outcomes from the school's inquiry-based integrated program. Currently, in Reception to Year 5, teachers of the two languages deliver the Integrated Studies program collaboratively in both languages.
Another important feature of the Primary program is the emphasis placed on fostering a love of reading. All students in Years 1 to 6 have a daily twenty-minute reading period, which may be guided by Chinese or English teachers.
