The International Schools Review Forum

I am seeing a lot of Asia and ME schools post jobs. Not so much for Europe. Is this a function of higher turnover in the former, or is it because the latter start posting/recruiting later? When can we expect most jobs to be posted?

Due to local labor laws, European schools have late timelines. Not the same for asian schools, where labor protection is minimal especially if you are in private sector. As a result, Asian school admin is more authoritarian in a sense. So, they can make up and 'play' with timelines.
A few European schools offer monetary incentives to teachers notifying early in the year. So, you might see a few early vacancies in some schools.
I'd be looking at major European school websites in addition to relying on the associate. No harm in attending London fair. A good chance to get hired by European schools.
