I also fear I have completely messed up with him.
I've tried to be a supportive but not too pushy parent which has resulted in me "trusting" the school to do what's needed without interference and several bouts of intense nagging (from me) for him to do more, interspersed with periods of backing off and leaving him to it.
I don't feel the school has been supporting him/pushing him as they should, he's one of those children who does just about enough to keep out of trouble, isn't disruptive and seems fairly invisible to the school.
At the same time, my "managing" of him has left him unable/unwilling to manage his school work himself, but if I hadn't pushed a bit in recent years he would have worked even less hard.
He's just about on track to get Cs as things stand, which saddens me because he had such a good start at school and clearly isn't daft. He was on the gifted and talent register for maths and literacy in infant school! His lack of achievement is entirely down to lack of application IMO.
Is there any one thing I can do to make a difference as we go into year 10?
