or do they have to go through local authority approved agencies? I worked in secondary for many years. I resigned when I had my son and have worked as a private tutor for a few years to fit around his primary years. My DH has a full time job. I have been volunteering in my DC primary school and really like it. To the degree that if they were likely to train me up (I can give my time for free at the moment and can fit it around my tutoring) could I then be directly employed as a supply teacher by them on an ad hoc basis?
