DS goes to an independent school where boys and girls have separate sports lessons and separate changing rooms. Although the boys are supervised in getting changed at the beginning of their sports lessons, the actual lesson/sports activity tends to end at break time. The boys are then expected to get changed during break. They are left alone in the changing room, and are invariably unsupervised. DS is in Year 4 and I am a bit concerned about them being left alone from a health & safety aspect. Can any school staff advise on the legalities here? The school is well staffed.
