Most answer keys are written by the teacher who set the paper, for the teacher who set the paper. They lean on shorthand only the author understands and assume context only the author has. The result: a free period evaporates while a substitute decodes the key instead of grading with it.
What a gradeable key needs
- Numbering that matches the paper exactly — same order, same labels, no gaps.
- The marking scheme inline, so the grader sees where each mark is earned.
- Acceptable alternatives spelled out, not left to judgement.
- A layout that puts the answer next to the question, not on a separate sheet.
The test is simple: hand the key and a stack of scripts to someone who has never seen the paper. If they can grade a script start to finish without asking you a question, the key works.
Marks shown where they are earned — no separate scheme to cross-reference.
If your answer key needs you in the room, it is not finished.
