My DD is Y9. She has a Chromebook we bought for her, but it has the school's software and is monitored by the school.
Before the summer holiday she left her Chromebook on when she went to speak to someone and another pupil wrote something offensive on it. It was flagged up and she was spoken, luckily the other pupil confessed (and also said sorry via WhatsApp, so it was documented and no further action taken against DD.
Today she was with her best friends and one of them asked to borrow her CB and wrote something about their mutual friend (who was with them), thinking it was a "giggle". It was that this girl was a S**t. The girl who it was written about also found it funny.
This was of course flagged up and DD has been given a detention and behaviour marks. She didn't want to implicate her friend who wrote it (and the friend gave DD money).
I've tried to impress on DD the seriousness of the situation and that she must never let anyone touch her Chromebook again. She's tried to imply that I'm telling her to not trust her friends, but doesn't understand that they're writing things on hers, not theirs, which isn't cool.
I've no idea what else to do. DD wants me to tell the HoY after the detention, that it wasn't her, but I can't help but feel that the Chromebook is her responsibility and that she's responsible for what is written on it, even if she didn't do it herself.
I'm worried that this will keep happening if she doesn't stop it being used. There is no way to lock the screen as the school's software doesn't allow it.
Is it worth mentioning to the school or not?
