I am a current parent of two children at ICS. We moved to HK from the US last summer and after touring many many schools, we found ICS to be the best fit for our children. The curriculum is top notch and the teaching staff is first rate. ICS had the highest scores in HK last year on the SAT. The class of 2011 has kids accepted to Stanford, Harvard, University of Michigan, Parsons School of Design, Northwestern University....just to name a few.
It is not easy to get into as an earlier poster claimed. The admissions process is quite rigorous and many children are turned away each year. One thing to know-this is an international school in that many of the children hold US/Canadian/UK passports but to look at the school, it is 95% Chinese.
