I doubt it. Free schools are no different than Independent Schools (of which there are far more), and it has always the case that you do not need either QTS or QTLS or any teaching qualification to teach in these schools. Indeed Free Schools are modelled on Independent Schools. Yet there has never been any flow of staff from FE to the independent sector, (although if you can teach Latin, or have an Oxbridge degree, you might be in with a chance). The reality is that initial training providers (often FE colleges) have been training more FE humanity lecturers than are either needed in FE, or schools.
