At each parents evening (for one of mine) we get a piece of paper that lists strengths, areas that need to be developed, and in 10 mins or so a parent and teacher mutually agree what the 'goals' are going forward.
I think it's a great idea and after coming away from DC's parents evening (at another school) with only a VERY vague idea of how they are doing I couldn't help wondering how this system might universally improve things?
