Retraining as a teacher...Help?

Are you in the UK ? If so you need to be a graduate, only FE colleges will accept people as lecturers (not teachers) without QTS status. They quite often like people to have industry experience and then train for their QTS on the job. For primary though you will have to do the conventional 4 year route - either a 4 year B Ed or a 3 year degree in a relevant subject and a 1 year PGCE. Any other routes are very rare and the present government is slashing funding for education so school are not offering training placements in the way they did under Labour (schools had to partly fund this themselves and the funds just aren't there anymore).
