hmmm - looks to me like you're a parent who is holding up your end of the deal beautifully... but the kid and the school - not so much right now!

could you maybe book him a session or two with a homework/study skills consultant with a view to cleaning up his piece of the puzzle? sometimes simple stuff like that goes a long way with a kid, especially if they're having a tough time being straight with a parent - or facing the teacher after the fact.

Every Sunday it brooded and lay on the floor. Inconveniently close to the drawing-room door.
