I started as an NQT in a school last September, and took over the teaching of a Year 10 group (now Year 11). They are a bottom set group - low ability - and can be incredibly challenging, behaviour wise. The dreaded controlled assessment moderation deadline is looming, and it has recently come to light that the group have quite a few pieces of missing work; individual assignments, obviously due to pupils absence. This was pointed out to my HoD at the start of the year, but I was told that it was all right, and would be dealt with at a later date. Recently, my HoD and mentor have both collectively moaned about how I now have left it too late to catch up said pupils with missing work, when I have merely been following the Long Term Plans put in place. I have had pupils coming back to complete work, but I don't think there will be enough time to catch up the remaining pupils, as they seem unwilling to co-operate and complete outstanding work. I feel like I'm playing catch-up for another person's mistakes, but not really sure what more I can do. Are we even allowed to be doing this at so late a date? Every time I mention it to my mentor or HoD they jump down my throat about it. Any suggestions as to where I go next?
