I would really not recommend Hsintien (Xindian) Cambridge for your kids. The school is not bilingual, as they claim to be. They have 2 classes of English per day but all their regular classes, such as math, science, etc. are all taught in Chinese.
The majority of their teachers are made up of foreigners who have some teaching experience but do not hold teacher licenses, which they should as they are a registered school. They are regulated as regular Chinese elementary schools are, so all their teachers are all suppose to have teaching licenses - they work around it. The teacher turn over rate is incredibly high as they have major management issues and their pay is lower than buxhibans/anchingban (considering the hours they are supposed to teach).
The kids are usually from wealthy families that reside on the Xindian mountain. You’ll find the usual snotty kids, but that’ll be the same everywhere. The problem is, their English is poor, especially the pronunciation, because they learned it in Taiwan and they are all Taiwanese. This is a school for rich Taiwanese kids that have rich Taiwanese parents who want to brag about their expensive school. They do plan to send their kids abroad for University but will eventually find that, since their English is so poor, the kids will run into quite a lot of problems getting/fitting in.
The Chinese teachers are actually teachers that have their teaching degrees and are pretty good.
Also, the spaces are very limited as most of their students start attending since kindergarden and have priority.
This information coming from teachers currently teaching there or have taught at Cambridge.
I have attended Dominican School a while back and in my class of 25, I was the only student there that was comfortable conversing in English. The rest of the class had poor pronunciation and was all Taiwanese. They had travelled abroad and some had lived there for a year or two but was mainly rich Taiwanese kids that started attending Dominican since they were in kindergarden. So, actually, my Chinese improved, even though all of the classes were taught in English, albeit by heavily accented Philipino nuns.
No wonder my classmates all sounded slightly Philipino and were all prudes.
As for the education, it was ok. Nothing special. Competitive. They used to rank all the students and post that up in front of the class. I don’t really know if you want your kids to go through that kind of pressure. Back then, I had private tutoring after school and my life was basically all studying. There were no sports teams or after curricular activities.
