I was talking to my supervisor today as we were working out a marking scheme (possibly grading scheme in the US?) for an assignment I am marking for his class - that is, a breakdown of how the marks for each part of each question were distributed. He said he thought there was a word - besides marking scheme - used by teachers to describe what we came up with. He said his friend (a school principal) had taught him this word. But we can't think of it. He first thought it might be rubric but a dictionary investigation disqualified it. Is there a single word which means "marking scheme"? Any teachers out there who can help us?
