If pay and working conditions in Academies were better, then they would have no issue with hiring and retaining qualified teachers.
The fact that Academies ARE having issues with no-one wanting to work there, and with the experienced staff leaving, whether through poor SMT leadership or through being bullied and forced out as they cost too much, having worked their way up the pay scale and therefore being an EXPERIENCED teacher, surely shows that the way some Academies are being run is NOT in the best interests of the CHILDREN that attend that school.
And after the Academy has lost (in one way or another) their experienced staff, and replaced them with inexperienced, unqualified staff, that does not leave the majority of pupils in a good learning environment.
Migsy - you are a qualified Architect. You have decided to go into teaching. Rather than take a post at an Academy without training, you have opted to do a PGCE. Why shouldn't others who wish to change profession do the same thing? Would you walk into a classroom on 4th September this year and attempt to start teaching a mixed ability class with no prior training? No? That is my point, you can see that teacher training is necessary to enable you (and others changing profession like you) to teach effectively.
I'm quite sure that all these people saying that it is not a problem WOULD have an issue with this were THEIR DC in a mixed ability class at their local Comp, with DC's with SEN or behavioural issues, or English as a Second language, in the same classroom, and THEIR DC was being taught by an unqualified teacher in THAT situation.
