Have namechanged for this as slightly sensitive.
My DS walked out of his primary classroom after being dropped off today. His teacher didn't notice and he walked off the school premises without being challenged and got all the way home (5 min walk).
He is fine, and was taken back to school. He had no reason for leaving apart from some minor problem with a bit of equipment. He is normally sensible so would have put money on his not doing anything like this. He has been talked to by his teacher and the headteacher, and we will talk to him again this evening.
However, I'm concerned that he was able to leave school so easily. It was only possible because he did it in the 10 minutes between the classrooms being opened and the school main gates (which give access to playground and classrooms without going through reception) being locked (after the late bell had gone). The school sometimes have staff on the gates, but didn't today. I spoke to the headteacher, who said that it is normal for primary schools not to man the gates.
I have a good relationship with the head, so don't feel fobbed off, but really don't know how to react to this, and what, if anything, I should be asking the school to do so that this can't happen again. It seems unreasonable to suggest that class teachers should be hawk-eyed in the period before the late bell, as they generally seem to be fending off parents, collecting money and doing 101 other things.
What do other schools do?
