FWIW My elsest son is 14, my youngest 5 and i can not think of any converstaion I have ever had with another parent about my childs progress.
I recall having a REALLY difficult converstaion with a mum who was literally leaning through the window of my car trying to find out if DC1 had a higher reading age.
Have never never understood it. If DC is doing well teacher tends to tell me, ditto if DC struggling.
I used to hire a lot of people and never once asked one what their reading age was.
( am rambling now in that slightly embaressed way I do when people are being emotional)
