mamamia, I feel the same way as you do. My hubby's niece and nephews all graduated from CIS. We also know a few people who go there. All that snobbery is true. So a child who goes to CIS will fall in one of 3 groups: A. the super rich kids B. the academically strong ones C. land of no where.
I have heard of a case where a parent decided to pull out her child because they couldn't stand the snobbery. She felt that her child was given the wrong values in life.
ISF - I have "heard" that there is a frequent change in principals - apparently the result of the board which is made up of "knowledgeable" parents of different views. Also, as a school of short history, it could be of concern.
Victoria - My cousin enrolled her daughter in the primary school and decided to pull her out 2 years ago. She said the school was not yet settled, administration was chaotic, high turnover of teachers, no progress report to parents. I don't know how it is now.
SIS - our foremost choice. the drawback is simplified Chinese, but we will try to cope. Anyway, the international trend is simplified Chinese. After all, there is less than 30M people in the world still using traditional Chinese.
SIS primary school only has 8.5 hours of Chinese/week. In many ways, it is also taught as a second language, only at a higher standard. I think that it is important for parents to guide the child to do more Chinese reading because it is a difficult language to master.
