Thanks @NotDonna . The other alternative is to simply not reply, as a taste of their own medicine.
DD is currently going to school 2-3 times a week. We just inform school that she is too unwell to attend. Which she is, but only because of the huge anxiety that school is causing.
I explained the whole shebang back in February to HoY, Pastoral, SENCo and Tutor (by email because I wanted them all to have the exact same info at the same time) and why study leave ASAP would be good. I got a patronising reply back from HoY basically saying 'I can see you've thought carefully about what's best for your child but I know best'. There aren't enough eye rolls🙄.
I don't care anymore about her attendance. It's just that I'd expect common sense and clarity from any school. I'd rather not have to judge DD's state of mind every morning and make a rushed decision every single day about whether she's well enough to go or whether her cortisol levels are going to end up killing her.
Essentially, DD s in charge of deciding when it's worth going in and when not. She is sensible and wants to do well, so we've decided to trust her on that. And here is the kicker - her tutor spoke to her and told her essentially that attending revision may help refresh her knowledge but she understood that it's her life and her exams, and she should do what she thinks best.
Her school seems to be split into teachers, who are mostly very good, and the SLT, who are mostly useless. Some of them are also teachers so I'm assuming their heads must be about to explode any minute now. It's actually quite sad.
Sorry for the long post. It's therapeutic to get it all out and to see that I'm not the one going mad!
