I'm not a teacher and neither do I have a dc at this school, but it is in my city so am a bit interested.

It's a local comp whose headteacher has decided to not use grades or traditional marking of students work. Instead they say they're introducing one to one feedback. The HT says it's better for the pupils confidence and gives his teachers a better work/life balance.
Does anyone have experience of a school that does this? Is it effective? Personally I'm not totally convinced that one to one feedback on all work will happen all the time in all cases but that might be me just being a bit cynical.
