I guess their stated marking policy then was one marked piece a week, even if misguided. My main point though was that some (many?) schools seem to be unable to hang on to computer science teachers once they have recruited them, for a mix of reasons. I also don't think some Heads realise just how much work is involved when a new CS teachers joins them, they seem to have unrealistic expectations. It's highly unlikely a new teacher is familiar with all the software used by teachers and students when they arrive at a school, and the first few months involve the teacher becoming expert in what they have never used before - and it takes lots and lots of hours and hard work, on top of all the other sh** they are expected to do. So said teachers leave as quickly as they arrive.
