I have two kids at SAIS, 7th grade and 2nd grade. They both love the school. It is a new campus. The teachers are very engaging and communicate well with the parents. I am very happy with them so far. Apparently I don't have enough posts to PM you. Are you from the US? I was wondering how you felt ...
it depends on what you are looking for in the school. have you considered the new American School. They offer an IB American Curriculum in new facilities. www.sais.com.sg
If the multi-language is your major concern, then you should definately consider SAIS. They have the option to learn either Mandarin or Spanish 5 days a week starting from Age 3 and also have a Mother Tongue program.
