Hi there, even though the posts above were mostly from 2005 and 2006, I would like to add what I think HKIS is like today in 2009. Firstly, some background -- my daughter goes to HKIS currently; after waiting in line for 4 years, she finally got into HKIS 3 years ago at 5th grade. We are planning (hoping) to get her to another school in the next year or two (prep-school if she gets in). I just want to say this so that you know I am a HKIS fan, but not tie to HKIS either.
Firstly, I would like to comment on the religion thing mentioned in the posts above regarding at HKIS. You might note that while students are required to take religion, each religion course counts at only 25% the credit of a required course and 50% of the credit of an elected course. This says to me that HKIS has a religion background but religion is not the most important thing to HKIS. Also, FYI, religion class at HKIS teaches not only Christian religion but they also discuss other religion as part of the course. Religion diversity is probably a "must" at HKIS because there are many non-Christian at HKIS.
Regarding the trust fund crowd, some time we feel it too. There is definitely a bunch of rich kids at HKIS and they go to the best places in town and party at the Peak, etc., and some of their parents are CEOs and HK establishment, etc. So sometime that can be difficult (and we are not rich and it has not been easy to put my daughter thru HKIS).
But I think it is also important also to point out that, more than the religion thing and the rich kids thing, by far the most thing to know about HKIS is that it is very competitive prep-school. Every kids competes to get good grade at HKIS - you get that from the teachers, from the parents, and most of all from the kids. The first thing HKIS 5th grade home room teacher told us is that "every kids study here." The peer pressure from kids is also not where kids go to party, but whether you get in the honor roll "with" distinction or not, and whether you get into the John Hopkins talent search or not, and whether you get to represent HKIS in writing or not, etc. My daugther gets many offers to play, but is more affected by peer pressure in doing well in school! I would say that the environment is definitely everyone competes, and the culture is definitely about studying, at least at the middle school level which is where my daughter is now. The main thing about HKIS as we discovered is that you will need to prove yourself academically, but once you do you'll have a whole world of academic opportunities open to you.
Also, HKIS is more like a prep-school than a local school for each kid has to be well rounded - big emphasis on sport and music, and learning from field trips etc. I would say HKIS, along with German-Swiss, CIS and some people say HK Academy and Li Po Chun United World, and maybe a few local schools like DGS/DBS and St Paul and a couple others, in the last couple of years at least (arguably at least), are the top secondary schools (at least up to the middle school level) in Hong Kong.
Lastly I would like to say something about a comment above regarding whether you are an outsider if are not rich. Well, we are definitely not rich. But I don't think we were ever overly treated as an outsider. Like any other schools, kids have to find a place in school for themselves, and schools are not always easy for kids. My daughter was accepted by her peers, and did it by being in a competitive sport team, and by being in the school orchestra (most people have to be in some kind of music anyway), and competes in a international academic competition.I think what I am trying to say is that HKIS is a tough place for kids just like any other school would be, but HKIS is definitely a good school and not a country clubs for the rich set.
Anyway, goods luck everyone in our pursue of our kids education
