Great news for your son, FlicketyB ! Something to celebrate over Christmas. And, em , your son will be a better teacher for having had a taste of the 'real' world. As a school governor, I interviewed a great many applicants for subjects right across the curriculum and often found that late entrants to the profession had a great deal to offer. Having said that, some members of the existing teaching staff could be suspicious of them - I don't know why. Perhaps they felt threatened in some obscure way.
There may be a shortage of teachers in some subjects like Maths and technology, but my neighbour's daughter graduated in the summer with a good degree as a primary school teacher and is still having to rely on supply work.
