foreign lang, computing, maths and one other I believe.Its even worse now in some subjects. Got a Physics degree and no job? Do you PGCE and we will give you £30K to train, tax free. After that go and get a job elsewhere with the cash you saved.
If not, some school will hire you, on an inflated starting pay grade no matter how crap you are. Science teachers are in short supply.
and it's £40k now...
