I have my PPA on a Wednesday afternoon and I am covered by my TA and another member of staff. My class is a slightly rocky little bunch, lovable enough but they need real structure and clear expectations. This afternoon I popped back into the class at 3.25pm to make sure some trip letter were handed out before home time at 3.30. I had carried various folders and sheets into the class and the teacher and TA were getting ready to dismiss the children. I began to lay out some worksheets as the other staff dealt with the children. We dismiss the children to their parents directly from the classroom, through a door and onto the playground. There were 3-4 children left on the carpet when one of the mums came up to ask for her son. At this point I was close to the door, my TA was outside talking to a parent and the cover teacher was on the carpet with the children.... the boy in question appeared to have walked out of the door without being noticed. I was in complete panic but he turned up on the playground however I can tell there will be complaints made (and I fully understand why). I am a little unhappy that I was not actually teaching the children or dismissing them I had just come into the classroom whilst doing PPA chores to be confronted with this. Has anyone else had similar experience with anything like this?
