Whilst my child attends the ISB rather than the SIS, I did go and look around both. The SIS seemed a friendly place for young children to be, but the facilities there were very limited. Having said that my son is now 16 so we were looking at it from probably a different view point to you.

If my son had been younger than we would have had no problems putting him into the local school system if we were going to be here on a long term basis.

I have to say that my advice would be to look at as many schools (local and private) as you can, you will know the school that you will feel happy for your child to attend. Good luck!
