Could I get in trouble for this? I was in a school on supply on Friday, in a year 1/2 class. There were a number of children with behavioural issues but I was not filled in on any of these (it was last minute and I was straight into it with no briefing). The children went off to lunch but one child stayed behind with his work. I had noticed the other teacher talking to him earlier but nothing was said to me. The child told me he was grounded and had to stay to finish his work. I sat down with him for a few minutes to check he understood the task then went to the other side of the classroom to do the marking. The classroom door was open. Another member of staff happened to walk past and see. She sent the child out immediately and told me that should not have happened. I feel so stupid - I was totally unaware that you're not allowed to be in a classroom with a child - I'm an NQT and for my final placement, teachers, including myself were regularly alone in classrooms with children. The supply school told me that it's a blanket rule though. I'm concerned that there are other things I should but don't know. I've read everything I can about safeguarding and welfare but does anybody know of a good guide to all the basic rules and regulations since I don't want anything to happen like this again. I spoke to the supply agency and told them what had happened and they said it wasn't a problem as long as the school hadn't complained which they haven't. I just hope that's the end of it. I must say though, it's really taken my confidence away because I feel so clueless. Any advice?
