I know of one Indian school in Beijing. It is operated by the Indian Embassy and is located n Guanghua Lu. I think it only caters for ages 4 - 11 years. I think it follows the Indian Central Scool Board curriculum. The email I have for them is indianembassyschoolbeijing[at]yahoo.com Please check with them to confirm the accuracy of this information.
There are though quite a few British Schools in Beijing.
Hey i hope you were able to find a suitable school for your children. I am an Indian too, will be in Beijing next month.my husband is shifting jobs. I am also looking for a school for my 10 year old girl, I believe the school inside the Indian embassy got shut. Do we have other options. where are your children studying right now. Can u please help.
