I have no recent experience - I worked with someone who worked at the school about 7 years ago and hated it (she not only broke contract, but was able to get a job at another international school in China because the Head 'understood' why she broke contract. That's unusual to say the least, as schools usually support each other!).

It might have changed - my general rule of thumb is to avoid 'for profit' schools as much as possible.

Why don't you contact your new school and get the names of families who are leaving. You may be able to 'inherit' a first class nanny.

I am not aware of any school offering a premium for IB experience. In fact, many teachers from Australia/NZ/Britain have been frustrated with many of the IASAS schools because they receive no premium for their Graduate Diplomas in Education or PGCEs. Even though the course content is similar to the US Masters degrees (I've done both, and the US Masters I did was actually easier!), only Masters credits can be used for salary advancement. I'd advise anyone interested in being in international schools long term to get a Masters - not only do you often get paid more, but it makes you far more competitive during recruiting season.

This varies from school to school. In my experience, many schools pay a small premium for those with a Masters (about$1000 a year).

However, there are some schools (usually the large schools in Asia that were started by US embassies - JIS, TAS, SAS, ISBangkok) who pay a large premium for extra experience. At JIS, for example, the school has 8 levels of qualifications (Level 3 is just a B.A. or equivalent. Level 4 is B.A. plus 15 masters credits or half a masters degree. Level 5 is a Masters or a B.A. plus 30 credits. Level 6 is a Masters plus 15 masters credits accrued after achieving the Masters. Level 7 is a Masters plus 30 credits. Level 8 is a PHD.) The difference between each level is about $3000 at each step of experience.
