There are courses GTP (Graduate Training Programme) where you study whilst you teach, but competition is very serious for these and I think you have to find a school to sponsor you once you've been accepted. You're right it's eriously competitive in teaching generally at the moment, but especially in Primary. Whichever training you choose, competition will be fierce and, after the course, competition for jobs eveb fiercer. As to the Primary /Secondary debate, do you want to teach your subject? In which case you need to look at Secondary. Or do you want to devlop young people's abilities, talents, social skills etc. right across a whole range of subjects- choose Primary.
