My son goes to CIS. He was there in Reception and is now in Year 1. I have to say, before he started I was concerned. There were so many rumours about how the school is too academic, the parents and kids snooty, teachers too strict etc.
I have since discovered none of it is true - I've never experienced it anyway. We're not wealthy. We did not buy a debenture (are you kidding?!). Are not well-connected in HK etc.
My son loves the school. The teachers he's had have shown themselves to be committed, encouraging, very open to parents' concern, actively discourage outside tuition (really), make great efforts to help parents help their kids. I am so impressed with the teachers, I can't say enough nice things.
The kids - First of all, the school is big on discipline and respect. The kids, especially the older ones, I have found to be well-mannered, helpful, and surprisingly watchful and considerate of the little kids. Also, my son has told me on two occasions that he fell while playing in the school playground. On both times, he said some of the older children took him to the nurses office to get looked at. No-one he knew. Just older kids. There are also few kids from our building who attend CIS - all older kids from 8 years old and up. All super polite. They greet you when you or they enter the lift, they old the doors open for you, invite you to walk before them, (usually) thank the driver and bus mom when they get off the bus (something I am sad to say I have never seen the kids from FIS, HKIS, South Island and Kellet (buses that come to our building) do. NEVER.
The moms- sure there are some unfriendly moms but they are very few and far between. I found them normal and so not from another planet! And dare I say, most are really really nice.
I actually think these rumours were started by bitter parents whose child did not get a spot at the school. Its not a perfect school, perfection does not exist. But my fears have been dispelled thus far and I am pretty sure it will continue this way!
