This is something of mystery. I got mine from the Teachers Pension Scheme. I don't think the requirement for QTLS does, but I could be wrong. Ask your college. But you might take the view that it would be in your interests to obtain it anyway. This is a big mistake. You need a portfolio of post qualification experience. It is unlikely that you can generate this at this point in your career. You do have a DFEE number, you just don't know what it is. Your PGCE qualifies you to teach for five years. You must obtain QTLS within that time (at least in England, and as matters currently stand).
