Op I didn't necessarily mean by you may be dd alone, but being quite honest I also wouldn't be surprised if the reality were by you/her dad too.
the teacher has seen the same thing I have
Exactly - if
You don't know at this point and you don't know if this was a last straw thing either
So it is a question of who is more likely to be truthful and her track record there isn't stellar is it?
this isn’t a good attitude to schoolwork. It’s disrespectful
It's a generally poor attitude to life. We all have to do stuff we don't like/aren't interested in.
I'd be questioning when she actually did the work - sounds like AFTER getting a detention to me. It wasn't me, I wasn't there, I didn't do/say that, etc etc is all std teenage BS when they're in trouble
Yep .
It is not disproportionate.
Agreed
I just have a different approach to parenting than you.
But your approach isn't working is it? Not totally
And if your attitude is ‘I don’t like that task and therefore I don’t need to do it and will just do what I want’ then that’s pretty poor.
Absolutely
@Pumperthepumper that's not what critical thinking is 
Most adults can tell the difference between vital tasks and pointless ones
They also know that even if they judge a task as pointless if it's part of their job and their employer is telling them to do it they better do it or risk getting sacked!
Good Lord!!
I’m not a tyrant parent desperate to punish my kids for breathing but I don’t think it does them any favours to make out they’re in the right always either.
Exactly it!
So, fear? Make them scared to fail?
Ffs utter tripe!
You appear to confuse fear with authority!
Too many parents these days are afraid themselves - to discipline, to act with authority
Too many are too keen to be friends with their kids rather than be their parents - cliche but often true
And the child didn't "fail" here you can't fail if you haven't even properly tried!
Op you've ignored or batted down almost all suggestions for consequences issued at home.
Homework doesn’t count against OPs daughters final grades though.
She's in GCSE years so it's possible they're at least component parts of coursework at times
If this had had happened then the homework would have been done.
Yep
@EarringsandLipstick my posting style runs to the long and detailed 
not for everyone I know. I don't think my opinion of the op or even her daughter is unnecessarily harsh, I think she's allowing her and her daughters lives to be harder than they need be by not properly addressing this - whatever the cause.
a simple 'have you done your homework?' is enough, unless there are significant issues with the kid.
And I and many others think there is an issue here that needs to be addressed
There are 3 possible causes:
The dd just generally cba with school and needs motivated
The dd is genuinely struggling and needs support/restreaming
The dd thinks these subjects - that she chose - are now beneath her as she has changed her career goal
All 3 are in need of parental input
There's nothing to suggest that OP's discipline is in any way lax.
I beg to differ!
Op repeatedly ignores, dismisses or criticises the many suggestions for consequences that have been made.
This suggests to me and I believe the other pps who've made suggestions and yes been critical of
Ops approach to the situation that there is a reluctance to enact consequences.
This IS a difficult age and stage teens need as much input as any other age they do have a lot on their plate. But actually having clear expectations and boundaries, a good routine etc really helps!
I had a different problem with my dd (no teen is perfect!) in that she would push herself TOO hard and over commit and knacker herself!
I had to make sure she took breaks, didn't commit to doing something after school every weekday etc
She was ambitious but needed to learn to pace herself.
That's our job as parents, to really see how they're doing, help them achieve as best they can and learn how to manage the demands they have on them.
Dds bff at this time had her first serious boyfriend, her parents had to navigate that. She was fine at school and did her homework but she was spending every spare minute of her time with the boyfriend and when at home supposedly sleeping on the phone/messaging - it wasn't healthy. In her mind it was a Romeo and Juliet "us against the world" thing to her parents they could see it was too intense and physical energy wise she was heading for burnout.
It's such a tricky age to parent, but clear and consistent rules and management of their time and things that keep them healthy like enough sleep are so important.
