I have a friend whose children are (or has been – the eldest is now in Concordia) in Pinghe. Yes, they do have boarding facilities, but it is not necessary for your children to stay in campus. My friend’s children goes home every day (it helps, I guess, that she has a car and driver for them).
The Singapore School may have a majority of lessons in English, but we offer 4 tracks of Chinese – the local Chinese syllabus (native standard), the Singapore Higher Chinese syllabus (near-native standard), the local CSL syllabus (Chinese as Second Language) and Basic Chinese (for those with no language background). While we only offer about an hour of Chinese a day, we do have an hour of Chinese Culture a week, and Music and Art are taught in Chinese. Our children generally bilingual in English and Chinese, though each nationality has its preferred language (Singaporeans and Malaysian = English, Taiwanese = Chinese and so on).
Hmm…my boss had better give me a raise for crossing over to marketing as well! Heh.
