NQTs and unqualified teachers are dealt with by the same mentors in my school, it is very much the same thing, being an unqualified teacher is slightly easier, I think, much less paperwork, anyway.
There has to be a mentor available for the NQTs, and they are paid extra and have less timetabled lessons. The same person deals with the unqualified teachers.
A lot of people prefer going into teaching through this route, rather than PGCE; a lot cheaper, you get paid from day one, rather than having to pay tuition fees yourself, etc. and a LOT less irrelevant faffing about.
You have weeks of lectures, have to conduct research, reading, write essays. Any time in the classroom is carefully built up, your contact time is tiny and starts with observations and you are constantly observed.
exactly this sort of irrelevant faffing about!
