I Want To Be A Primary School Teacher, How Do I Go About It?

There are lots of routes into teaching.  Im just about to exit from the raf and went down the Flexible route.  I got a open university degree (any for primary got to be subject specific for secondary) and then as i needed an income went to the uni of hertfordshire on their flexible programme (PGCE).  This fitted in with service life as i studied online and organised school visits (for the tasks) in my own time.  There was a five week and a nine week block which needed to be spent (and passed) in a primary school and eventually when youve jumped through lots of hoops (skills test etc) the course gives you QTS.  
Do you have a degree? If you do you might find the PGCE 1 year course i for you.  If you need an income then the GTP (graduate teacher programme) might be for you where you work in a school for a year getting 15000 or so while you teach/study.  The flexi route fits in alongside your work (the way i went) or if you dont have a degree yet  you can take a uni course for 3 years which gives you a degree at the end with QTS.
Either way at the end you will have a degree!  I think you also need a minimum of 3 GCSEs (maths, english and a science) but im not too sure on this one.  
Hopefully this gives you an insight but you can find more details on the TDA website.  Regards
