One to watch out for. University pay should be fixed in Beijing, but watch out for hour creep. Anything over 15-16 you should get overtime.

Although KUST has a good reputation academically, beware of KUST attached colleges.

I worked at one, they say they only offer hourly pay, no flights/visa etc. So technically you are illegal, even if you have visa to work elsewhere. They then proceeded to break a lot of the verbal agreements I had made, simply stating 'not in contract'.

I interviewed at another KUST college for a post, they wanted a DOS but were only paying teacher rates of pay, and very low rates (much less than 100/hr). They suggested I supplement the income by teaching 30/hr per week. Also they would not pay for any admin I did (as DOS) only teaching time.
Any management that would let someone try to teach 30hrs/wk is not good. Yes you could do it, I am sure that there are teachers who would, but quality would suffer. As would the sanity of the teacher.

Thanks for all the useful information. Is there any demand for foreign (non-Chinese-speaking) people to teach subjects such as math and science in the universities? Of course the Chinese-speaking staff can do this well, but I figure there must be some demand, for example by students preparing to apply for graduate school in western universities. Just checking as I would prefer to work in a university but do not want to teach language classes!
