How much do you monitor teens homework?

[FarAwayHills]

DD is in year 8 and has always been pretty good about school work. At the beginning of Y7 I helped a bit mainly by reminding or prompting about what needed to be done by when due to lots of new subjects and multiple deadlines. In Y8 I have backed off allowing her to be more independent and mange things herself. I do ask about homework but she always assures me it's all under control. So last week she totally forgot a project that was due and this morning she realised that she had forgotten about some homework due today.

So do I revert to the more hands on approach or let her face the consequences at school? I would be interested to hear what others do with teens and homework and if you let them manage things or do you get more involved? I also suspect that her constant attachment to her phone is having an impact so I might have to put some rules in place there.

Went to parent's evening on the other night and teacher told me on that very day ds had forgotten his homework and she said "I believed him, he's a hard worker and this is a one off" so he avoided detention because he has built a reputation for being dependable. He had genuinely left it at home too! There was no need for a punishment - it would have achieved nothing.....but I'm sure the kids who frequently get detention for no having their homework with them were a bit peeved.
