Mobility and highly effective teachers : re-visiting beliefs about 'over-stayers'

There is a long held belief in the teaching profession-a belief approximating the status of folklore-that when a teacher stays in a school for an extended amount of time, the enthusiasm for the job wanes and becomes less effective, turning into the 'living dead', awaiting retirement. In this folklore, then, teacher mobility is positioned as desirable-with positive outcomes for the profession and for students. Two recent studies and faculties in NSW government schools, however, suggest to us a need to problematise the notion of teacher mobility as an automatically desirable aspect of the profession. We think these studies suggest a greater degree of complexity around the issue of teacher mobility than simply viewing the 'over stayer' as a cynical quasiretiree or 'shell back'. In fact, these studies of teachers who achieve outstanding outcomes in the NSW Higher School Certificate (HSC) and of faculties and programs achieving outstanding outcomes in years 7-10, suggest that length of time in a school may be directly correlated with outstanding outcomes (by underpinning a range of other factors probably more directly causative of those outcomes)
