I've name changed for this as I think the school might be quite identifiable.
Our school has now announced that senior school pupils are being given study leave during prelims. It's eight days in total, but as it finishes 1.5 days before the Christmas holidays, I'm guessing that many pupils simply won't go back until after Christmas.
I'm far from sure about it - it's not happened before and it seems a bit unnecessary to me. I'd prefer my DC to be in school during that time - even if classes outside the actual prelims were spent doing revision, they would at least have the teachers on hand to help with difficulties etc. I'm just interested to know if this is a general trend now?
