After a decade of relentless reform in a climate of shaming and blaming teachers for perpetuating poor standards, the attractiveness of teaching as a profession has faded fast among potential new recruits.
Teaching has to compete much harder against other professions for high calibre candidates than it did in the last period of mass recruitment, when able women were led to feel that only nursing and secretarial work were viable options.
