A rubric is a teaching tool, not just a grading one. Four short lessons on building rubrics that make marking fairer and faster, then a self-check.
Rubrics come in two broad shapes. An analytic rubric scores several criteria separately; a holistic rubric gives one overall judgement against level descriptors. Each fits a different job.
A rubric only makes expectations visible if students can read it. Vague or jargon-heavy descriptors leave them guessing — and leave you re-explaining at marking time.
A rubric improves consistency, but it doesn't guarantee it on its own. When several people mark, or one person marks a large pile, judgements drift. Calibration and moderation keep them aligned.
The rubric you built to set expectations is also what makes marking faster and feedback clearer. Let it carry the routine load so your comments can do the rest.
