Marking & moderation — a crash course

Marking is where fairness is won or lost. Four short lessons on grading that's consistent, defensible and humane — then a self-check.

The one thing to remember: a grade should mean the same thing no matter who marks it, or when. Moderation is how you make that true — and protect both students and staff.

The lessons

1
Rubrics that workShared criteria, in plain language

A good rubric makes standards explicit for markers and students alike. A vague one just hides the disagreement.

  • Describe observable standards at each level, in plain language.
  • Share the rubric and exemplars with students before they submit.
  • Pilot the rubric on a few scripts before marking the pile.
2
Consistency & calibrationMark the same way, all the way through

Markers drift — across a pile and across a team. Calibration before and during marking keeps grades comparable.

  • Calibrate the team on common scripts before starting.
  • Re-anchor yourself periodically against the rubric and exemplars.
  • Mark question-by-question, not script-by-script, where you can.
3
ModerationCheck before grades are released

Moderation is the quality check that a sample of grades is fair and consistent — ideally before results go out.

  • Moderate a sample across markers, grades and boundaries.
  • Document moderation decisions and any regrade.
  • Use moderation to improve the rubric and brief next time.
Grounded in
  • Pre- and post-marking moderation practice
  • Cross-marker calibration
4
Fair & sustainable at scaleHumane marking that holds up

Marking is exhausting and easy to rush. Designing the process protects fairness and the marker.

  • Front-load common feedback; reserve detail for what matters.
  • Build in breaks and a consistency check to fight fatigue.
  • Keep enough record to defend a grade if it's queried.
