It is still early in the season. The majority of NQT posts are filled summer term. The resignation date for teachers to leave for September is not until the end of May . This year the late Easter and extra holiday will also delay things.That said the good teacher training guide 2010 shows that 69% of Science PGCE's awarded QTS entered teaching. Demand does vary according to which science subjects you specialise in and which part of the country you are in.
