Rubric

A rubric is a scoring map—criteria, performance levels and concrete anchors. How to write one two raters can't disagree with.

Home›Glossary›Rubric

A rubric defines what each level of performance looks like before anyone grades: rows are criteria, columns are levels, cells are observable descriptions. Its job is to move judgment from the grader's head into shared, citable language.

🧮 Formula

Criteria × Levels × Anchored descriptors (+ optional point weights per cell).

✏️ Worked example

A presentation rubric's top cell reads "answers questions with evidence, admits unknowns"—not "excellent". Two raters, same grade, no meeting needed.

🎯 When to use it

Anything scored by humans on subjective material: projects, interviews, exams, portfolios—and every calibration session you'll ever run.

⚠️ Watch out

Adjective-only cells ("good", "adequate") outsource the decision back to the grader. If it can't be observed, it isn't an anchor.

Questions practitioners ask

Holistic or analytic rubric?

Holistic (one overall level) is fast for high-volume scoring; analytic (per-criterion) gives feedback and reliability data. Certifications want analytic.

How many levels?

3-5. Beyond five, raters start inventing differences that aren't in the work.
