We're from the US and I have a 3rd grader and one in Pre-K at OFS...I agree with the above poster about the
International School Curriculum...it seems like the teachers have the curriculum structured to suit the students' needs and are currently assessing the students to see where they are in terms of skill level...school just started here 8-11-08...
My sons both seem very happy with their teachers, classmates, etc...I on the other hand feel like the administration is disorganized and that the school is over-crowded...you would think that with all the money that people pour into the place they could update the facilities...it's very run-down...but, a nice-looking school isn't really what matters...
Anyway, I think the learning / teaching ability is there...So far so good. I'm not sure what grade you are inquiring about but I don't know of a waitlist for elementary...best thing is to call or e-mail...Good Luck.
FYI - SAS (Singapore American School) definitely has a waitlist...it was our first pick, OFS was 2nd...but now that we're here it's probably the best choice since some of the other schools are quite far from our home and OFS is close.
