DDs best friend does Teach First Primary and from what I've heard, I am a big supporter. I am a deputy head of a primary and, if we were in the right area, I would love to have a TF teacher.
I am so glad there is a lot of support on this thread, I am always nervous when I see TF mentioned as there is a lot of skepticism about it. Many don't understand it or realise the amount of training given is barely any less than PGCEs or School Direct (infact, often more than school direct). Yes it is not a perfect route, but all routes into teaching have their downsides. IMO all these advantages and disadvantages are equal.
The interview process is horrendously tough and 99% of the time they really don't let anyone in who isn't up to it and doesn't understand it is about the teaching and raising standards, not improving your CV or feeling good and all rosey about helping a deprived community
They do work right from when they get their offer completing time in schools, action plans to get their subject knowledge up to scratch and preparation work which involves very extensive interactive online modules. They then do the 6 weeks, which I have heard is very intensive and innovative training, followed by being mentored and supported throughout their first two years.
There is definitely a switch in attitude, the company require a lifelong commitment to education. The numbers who move out of teaching after two years are almost the same as other routes into teaching. Those who do it have something different about them to want to do Teach First.
To address EvilTwin's points:
You cannot underestimate the disruption to a school if the is a large turnover of staff. My issue with Teach First has always been the timescale- get the top grads in and get them to commit to two year's of teaching.
This isn't the case anymore, and if they do move from teaching many set up social enterprise, helping address educational disadvantage in other ways, or go into e.g. the civil service dept of ed. And, as I said, turnover is not much different, if not better than, from normal staff turnover in such schools.
Convince them it'll be good for their future career prospects and that this poor disadvantaged kids will benefit from their superiority. Sorry, but no. In my experience, kids benefit far more, in the sorts if schools TF targets, by getting from school the stability many of them lack at home.
I agree we need to ensure there is a steady flow of decent graduates into teaching, but am not sure that the "teach first, feel smug, pass on your genius then move on" approach is the best.
Any Teach First-er with that attitude would be filtered out in the interview process now (perhaps not 10 years ago when it was less oversubscribed)
I agree on your point if more TF participants are committed to make a long term career of it then this is when even bigger impacts will be seen. The King Solomons academy in London is a fantastic example of what can be achieved.
