I may be wrong, but isn't a PGCE basically the same as unqualified teachers do in their first year of teaching? My DH had a reduced timetable, a lot of supervision by other teachers, regular lesson inspections, had to watch other successful teachers teaching and regular meetings with the head of department.
They're not just picking someone off the street and then never checking that they're doing an ok job. If anything I think that system works better - they have real motivation to check up on the teacher.
Also, my DH's contract was probationary for the first 12 months and had to be actively renewed on completion of x set of results etc etc etc.
If so many successful private schools actively recruit uqt's directly out of top universities then it cannot always be a bad thing. Westminster, Trinity school, Eton... All of these schools recruit new graduates from Oxford, cambridge, LSE, Imperial.
Hypothetically - if you were picking a school for your child and one school had a UQT spoken of very highly by staff and students with excellent results to back it up, would you still not pick that school? Or would it only be if the teacher was an unknown quantity?
Presumably you credit the experienced panel picking the teachers with some intelligence? They generally have a pretty good idea of who is the best candidate for the post. PGCE candidates have a huge advantage anyway - , they prepare a huge portfolio of lesson plans during their PGCE year, up against an unqualified, inexperienced candidate if what you're saying is true then they should wipe the floor with them, if the unqualified candidate is the best there surely thats the right choice?
I do agree that there should be no difference in pay though - if they're good enough to be a teacher then they should be paid as such. It would also ensure that the schools were recruiting on merit not a financial incentive.
