My school has just done a 'welcome evening' for year 10 students and parents. Various staff were involved to promote aspects of study, anything from literacy to sleeping well. It was an extra 2.5 hours midweek starting at 6pm and ran on late. It wasn't on the calendar but a last minute decision to be added on. As a 'one off' (or so I thought) I didn't mind doing it. Only about 10-15 teachers are actually involved in the evening. It was successful and another similar evening is being proposed for Y11. What are the guidelines in terms of adding this directed time that isn't in the calendar? I'll do it as I think it will help the students and I don't want to kick up a fuss, it is only one extra evening, but I'm curious what the actual rules are (if there are any?) in case another evening likes this added as well. My HOD is wonderfully supportive and has suggested I offer an in-class/tutor time alternative that can be delivered during lesson time, with a homework set on Show My Homework so parents can see as well.
