The briefing provides a summary of current and comparative evidence from previous years related to teacher supply, teacher vacancy rates, attrition from the workforce, working hours and pay. It provides further summary overviews of financial incentives to improve recruitment and key policy initiatives, the Early Career Framework and the ITT Core Content Framework, followed by the Initial teacher training and early career framework (ITTECF). A standout point is that the number of teachers in state-funded schools has not kept pace with increasing pupil numbers over the past decade and the teacher vacancy rate has risen. A further important indicator of the ongoing challenges is that in recent years between 10% and 15% of teachers left the state-sector profession within a year of qualifying. Five years after qualifying, between 30% and 33% of teachers have typically left the profession.
