ERIS fees (apparently) are in the region of 12k a year. Heard that through the grapevine, so not sure if it's true or not. If that's the case, then you might be better off going to a smaller
International School, like Chatsworth, ISS, EtonHouse. You could drop them a line and find out.
A couple of things that I have noticed about them that make me wary:
-Spelling/grammatical errors on their website
-Promising the world! A new school that is going to be offering three hugely varying and demanding curricula... hmmm, I doubt it.
-Most of their staff are local. Hang on, before I offend anyone - this means that their teaching practices and training MAY be different to what expats are used to. (Not necessarily of course, I have worked with some fantastic local teachers. I have also worked with a few nightmares...) This can also be a sign of a school that is penny-pinching as local teachers do not get expat benefits, and are therefore cheaper to employ. Also note that they are following the Singapore school curriculum (well, one of the programmes they are running...)
I don't know, they could be fine, but I would think very seriously about putting a child there that was at an important part of their schooling. Kindy might be fine as there is plenty of time, but a grade 12 child would be a different matter.
On a more positive note, a new school might be bending over backwards to prove themselves, so they could be a great place to go.
