Add the awarded criterion points.

points

Add the maximum criterion points.

A total does not preserve criterion feedback

Two submissions can receive the same total through different strengths and weaknesses.

Keep criterion-level marks and comments beside the percentage.

Criterion evidence can also apply unequal weights to rubric dimensions, count criteria that meet a mastery cutoff, or place a resulting score within a defined reference group.

Point rubrics and level rubrics

A level rubric may use ordered performance categories whose numeric spacing is not truly equal. Converting labels to points introduces a model that should be published with the rubric.

Where the rubric already assigns criterion points, use those official values rather than recreating them from labels.

From inputs to result

rubric score = earned criterion points ÷ possible criterion points × 100

Every criterion must use the same point basis before its points are added.

A forty-point analytic rubric

A rubric awarding 34 of 40 points gives 85.0%, with six possible points not earned.

Check the scoring range before adding

A criterion scored beyond its stated maximum makes the combined percentage invalid.

Treat not-assessed criteria according to the rubric policy rather than silently entering zero.

Reconcile every rubric criterion

  1. Confirm the applicable rubric version.
  2. Reconcile each awarded criterion.
  3. Add earned and possible points separately.
  4. Retain comments with the total.

Questions about the result

Should an unassessed criterion count as zero?

Only when the scoring policy explicitly treats it as missing work rather than removing it from the denominator.

Does the percentage replace criterion feedback?

No. It summarizes points but cannot show which performance descriptions were met.

Can bonus points be entered?

Only if the possible total and maximum-score policy allow them.

Preserve a reproducible scoring record

Save the rubric version, criterion scores, scorer, date, and any moderation decision. A later total can then be traced to the performance evidence that produced it.

If several assessors score the same work, retain their original ratings before applying an agreed reconciliation method.

Rounding belongs at the displayed total unless the policy instructs scorers to round individual criteria first.

When a rubric changes mid-course, do not compare raw percentages until the criterion set and maximum points are aligned.

Before totaling, inspect whether criteria are independent or nested. A broad criterion that already incorporates several subskills can double-count evidence when those same subskills also receive separate points. The published rubric, not convenience, determines the additive units.

Moderation should address scoring interpretation before arithmetic. If reviewers disagree about a performance descriptor, averaging their totals may conceal the disagreement without resolving which evidence supports the criterion decision.

When reporting several rubric scores, sum earned and possible points only if the rubrics share an additive design. Averaging percentages gives a short and long rubric equal influence; pooling points gives influence according to their maxima. Either may be intended, but the choice must come from the assessment plan and remain consistent.
