All good points, especially this one: OP, instead of asking what's in it for you, you should be asking why a school would pay you the big bucks. If you're applying as an NQT, it's very unlikely they would do so unless your qualifications come from a top university, you have previous overseas experience and/or you have prior teaching experience, such as EFL or the IB. Are any of these the case? I would intend to minimize UK time as far as possible so I would apply at NQT and as a result I would not have impressive teaching experience. I do have an impressive professional background: Oxbridge, lawyer, business etc but none of that is very relevant. I did do a year of EFL teaching after university but that was a while ago now. Ultimately I have always felt a strong desire to travel, particularly to live in Asia and learn a new language but I cannot find any way to get there in a conventional career move (and I have tried). Switching to teaching was an idea to achieve the same end goal using a different path. However, in contemplation I think I'm too focused on myself and I guess this career path only works if your focus is 100% on the children you teach. By contrast, taking up a role with a focus on living in country X and enjoying life in country X seems like the wrong way of looking at things.
