Well, goose888, "high" and "very high" are relative terms, surely? A certain amount of staff turnover is perfectly normal and even a healthy thing, perhaps. Bear in mind that international schools usually have a higher staff turnover than similar schools in the UK. In any case, the fact that lots of staff are leaving a particular school might even be a sign that the school is IMPROVING, not that it is getting worse. When I was teaching in Doha, the new director did not renew the contracts of a number of unqualified staff, who should never have been given jobs in the first place, and set about recruiting more qualified and experienced staff.
