How should an essay be marked? You might think a teacher should simply read it and make a judgment based on the impression it makes: logically coherent, offers evidence to back up its case, reads well, is original – feels like an A. But that, obviously, is risky. What stirs one assessor might not appeal to another. So maybe there needs to be an agreed rubric. The essay must cover certain key points, achieve certain goals.
