We did all this a couple of months ago. Tanglin was full til Sep 09 at the earliest so we went on the hunt for an alternative while we waited. Emaar had spots available and seemed ok, but the facilities seems a bit sparce, although I agree with previous comments that the admissions dept was
prompt and very helpful. We viewed at lunchtime, and although it was noisy, there appeared to be plenty of adults around.
One World was recommended to us as the head is ex of the Austrailian School and highly respected. They have spent lots on the set up, but yes, if you want your child to make new friends in a scarey new country, then they might not even have anyone else in their class!! That will change but how long are you prepared for your child to experience that? We couldn't put ours through it I have to say.
OFS is generally considered an ok holding pen for lots of kids waiting for
places at other schools. New kids start every month so you don't have to wait for a new term, and there is no registration fee which is nice, but it is a massive school. In saying that some people love it so much they stay instead of moving on to the school they thought they wanted to go to! It certainly will immerce your child into an international family.
With the current eco enviroment, schools are finding they have places they never thought they should have. My 5 year old got into Tanglin a year before we expected to and didn't even have to start at another school thank goodness, and my 9 year old is at OFS waiting to tsf over when a spot becomes available, (thank God for a sibling policy!)
Happy hunting the worry of getting it right can be highly stressful.
