How the heck did this thread get resurrected after years and years?
I agree with shoppinmommy that the styles and academics is uneven at SAS from teacher to teacher, but I think that's based more on administration and not that they are expats as Taga-Bukid suggests.
They are teachers, hired as such to do a job, and are on a contract. The good ones are asked to stay on, the bad ones are not. Very, very few are 'trailing spouses'. There are over 300 now, some variation is to be tolerated I suppose.
Shoppinmommy also nailed the 'march to the middle' phenomenon. The overall test scores indicate it is a school full of high achievers, but I understand your comment. Lee Kuan Yew's grandson turned it around at SAS when his local school kept failing him. Turns out he was dyslexic and he thrived at SAS, since it was a problem they could deal with effectively. Nice to hear the Minister Mentor sing our praises, but you're right - the school has lost some of the breadth of a public school in the US, since it is under no obligation to conform to 'no child left behind.'
