I have worked in Northern Ireland as a supply teacher for several years as there are few permanent jobs here. I have taught all sciences to GCSE and some A Level Biology and Chemistry. I am thinking of making a move to England for September. My degree is in Molecular Science which has a good mix of biology and chemistry modules, so I could apply for jobs in either field. I thought it would be easier to get job as a chemistry teacher, but I read recently that there was now a problem recruiting biology teachers. Which science would have the least competition for jobs? I actually prefer teaching biology. Thanks.
