I have arranged a private French exchange for DS (14). The school don't do any language trips or exchanges and when I spoke to them informally about it, they were encouraging. It will involve him missing the last 5 days of term, as these were the only dates that suited the French family. I have applied for authorised absence, explaining the educations value of the trip. Today I've received a reply saying "The school is unable to authorise the absence, however will register the absence as an explained absence on this one occasion".
It then goes on to say how unauthorised absence is bad and you can get a penalty notice if you take a "significant amount".
So if the absence hasn't been authorised, then what does it being "explained" mean?
