Well in Espoo and Helsinki the school report is just a list of subjects and numbers. I find it totally impossible to sit down with my kids and discuss things like attitude, organisation, attentiveness etc when all I have for ammunition (sorry!) is a number in a box. The teachers have different standards so an 8 in French may be wow! whereas an 8 in Math is only par for the course. To be quite honest we have NEVER attached a huge amount of importance to school reports, unless there were personalised comments. I wish schools made a better job of this. We do look a bit more at trends though. So if one of mine goes from a 7 to an 8 then we give lots of praise. We have also given out cash for good reports but only very recently. I'm not convinced that works for younger kids unless they have a well-developed sense of the value of stuff and a wish list. It works well now though as mine are all saving for iPods and those things cost mega-bucks.
As someone who is over-organised and rather anal about tidiness (think Monica in Friends) I have always made a conscious effort not to inflict my handicap on my kids

My lads are MUCH more creative, spontaneous and dexterous than I am and I definitely do not want to stifle that. So I am fairly forgiving when it comes to some things such as care and attention. I can admit that some kids learn differently (ie they are really messy and their notebooks look like doodle pads) compared to my own very prim and proper school work yonks ago.
Also I don't have a problem with kids having "fun" in school. None of my boys has ever woken up in the morning and said "I don't want to go to school today". I do get frustrated with laziness though. If I think my kids have got a bad grade (eg in a test) just because they couldn't be bothered then I get mad (very). I tend to believe if kids mess around in the classroom it is probably because they are bored (ie the lesson is boring) so the problem is the teacher not the student. But I wouldn't say that to my kids. Of course there are exceptions like ADHD etc but that is a different subject altogether. Also, some kids just need er... more authority than others. Some teachers are maybe not firm enough.
We never did contracts with any of the boys. We just discussed lots... showed we were interested (not just in the results but also in the content of what they are doing in school) and I always ask, every day, what they have done in each lesson. It's much easier now, I think they have a better idea of what is expected of them and what they really need to do to improve a grade. With younger kids that's almost impossible.
Have also had issues with the "know it all already" attitude. eg in English and French. But I think that wears off as they get older and other kids catch up (the late-starters) and certain subjects become more challenging. I guess the teachers have strategies for dealing with that in the classroom.
The more I write the more I realise I am not answering your post at all
I'll think about it.
