Yes the child was devious but what were the school thinking?
Our DS went to a week's residential a few months ago. We had to drop him in the hall. We went with his luggage to the coach and got that stowed. Meanwhile back in the hall the kids were asked to stand in one area of the hall. Then they were called out to go and stand with their group leader (teachers going on the trip) - about 10 or 11 per teacher - and called again by that teacher to register them and to make sure they were with the right group.
Once all the children were registered they moved to the coach one group at a time and were counted onto the coach. When they were all on a final head count was taken by the head teacher who checked it with the teachers who were travelling.
When they got to a service station and needed the loo the kids were taken off in groups of five with a male and female teacher who stayed with them for the loo visit then went back to get the next group. Then they were counted again.
On the way back they stopped to get lunch at the service station. They were put into pairs to go and get their choice of lunch and had to accompany each other (so if one wanted a sandwich and the other McDs they both had to go to the sandwich bar and McDs). Then they were counted back onto the coach and a register taken.
What the hell could have happened if the coach stopped for a pee break and she'd got off? The numbers would have tallied and she'd be left at the services.
Plus you have to ask how the school didn't spot her missing? Our primary has a policy of ringing if a child missing registration and there's no word from the parents.
Bad all round and the parents certainly should not be entertained with the idea of compensation but the school seriously needs to look at its policies.
