The fees for 2012 haven't been set yet and from everything I've been reading recently, I'm not sure whether they will actually be £9000 like the undergraduate fees. It will take a lot of persuasion from the government to get people into teacher training if they've got to pay £9000 for fees on top of only being entitled to a loan of £3/4000 meaning they've got to use savings etc to pay for travel/rent/life during the year as they can not work part time. This is why the bursary used to exist and I think in the 2011 academic year trainee teachers will have a lot of finance issues that they haven't had this year as all of them are at least £4000 down in their bank balances than trainee teachers this year. Add the hit of an additional £6000 just to train and I think a lot of people just won't be able to afford it and the government are very aware of this, especially given postgraduate teachers already have a substantial amount of undergraduate debt.
In your PGCE the focus is on getting through it and into the NQT year. This is what drives you, especially near the end as you know it will all be worth it in September when you're teaching your own class. Having spoken to number of head teachers and my tutors at uni about this (I was considering doing a Masters in education first then my NQT year) they've all said to me that an NQT who hadn't looked straight for a job after finishing their NQT year would be looked on questionably in the application process. Obviously some teachers don't get a job straight away but schools want to see people who are still topping up their experience whilst getting a permanent job with supply/TAing/volunteering etc. They don't want someone who did their PGCE then ran away for a year or two... as one, I think on a personal level you'd lose a lot of the teaching momentum you'd built up over the year and would find it difficult in interviews to get a position when you're fighting against people who are current PGCEers. The PGCE is something that you really have to want NOW at this stage in your life. I know of 2 people on my course who started it with this vague idea they'd get it out of the way now and then go off travelling for a bit afterwards before doing their NQT year. They've both dropped out due to failing placements, not handing in work and generally not performing as it was clear that they weren't as committed to the rest of us as they had no real inclination of starting to teach any time soon.
If you're not sure about teaching this year, I'd say to you don't do it. Take time out to travel and do what you want first, then come back and see what your options are then. You could look at doing the GTP or Teach First for example, where you get paid a decent wage whilst you're teaching and it could be in 2-3 years time that teacher training has changed significantly anyway given the current ideas are to get rid of the university aspect and move it into schools. Whether this happens is another matter. For NQT jobs, applications start as early as January and can take months. I started applying in early February. Its now mid June and I still do not have a job for September. If you did your PGCE then went off travelling with the idea that you'd do your NQT after your gap year then you'd need to be back in the UK by February sort of time to get back into the teacher mind set, do some volunteering in schools and start focusing on getting a job which really only gives you 7 months away.
You're better off seeing ITT year + NQT year as one entity, as this is what it is in reality. The ITT year is just a training process for the training process, which is your NQT year. It certainly doesn't get easier in the NQT year from what I've been told and having a year out of the teaching mindset will just make it even harder. Also,all of the jobs chat and excitement is part of the PGCE and its been great talking to my friends about interviews/jobs as all of this makes it feel like the long nights and the stress of the PGCE are worth it as people are getting employment from it. If you're not part of those discussions as you're off travelling, I think you'll also feel incredibly out of the "teacher chat" loop in the second part of the course which from the experiences of the people I mentioned who did end up dropping out due to not really being focused on being a teacher now, just seems incredibly isolating.
