Historically teacher training has sat within, but somehow also outside, the higher education sector in England.
It’s no longer compulsory to train to be a teacher in order to teach in England – in academies, independent schools, and free schools at least – but some kind of teacher training is generally considered to be an advantage.
Neither is it required that a teacher holds a degree – though most do, and it is a prerequisite for some routes to practise.
However routes that included university training and postgraduate qualifications remain popular with trainees, and with schools of all types. So why are they disappearing?
