Normally if a child hands in coursework that is worth a 'D' grade, then that pupil is told how to improve it, the work is returned to them and they bring back a new improved version in a couple of weeks time. (Note that this extra help is only for the 'D' grade children because they are the ones that matter.)
As the deadline to send off the marks to the exam board draws near however, panic sets in amongst the staff, as there will always be a few lazy pupils who haven't redone their work.
A novel approach was explained to me last week by a friend whose department simply reports all the 'D's to the exam board as 'C's and only bothers getting the kids to improve their work in the unlikely event that the exam board select one of the inflated pieces of coursework to be sent off for checking.
Everyone's a winner. The teachers don't have to chase as many kids, the department gets more Grade 'C's and the school's exam results go up. I don't know why the practice isn't more widespread.
Oh hang on, it is.
