I've re-posted this from the science forum to see if other readers have any ideas ... I was wondering if anyone has any ideas to a problem we are having in our science department at the moment. We give each student an end of year NC target at KS3 but we inform their parents four times a year about their childs' NC level. Taking these snapshots of achievement has led to certain childrens' levels going up / down (as you would expect) throughout the year however their final NC level usually matches their target. I've explained to SMT about this issue but they've requested a solution ... of which I don't know the answer! What do other departments do to 'smooth out' this non-linear achievement in their faculties? PS Thanks to the earlier responses from bogstandardcomp and marshypops!
