What is a rubric – and why use one?

Making expectations visible

Every marker carries an idea of what good work looks like. The challenge is that this idea is often implicit – known to the marker, but not always shared with students, or even with fellow markers. A rubric puts it on paper. It turns the learning outcomes of a course into concrete criteria, and describes what a weak, adequate and excellent answer looks like for each of them.

Rubrics are widely used in higher education, both to support consistent marking and to help students understand what is expected of them. What makes a rubric a rubric – rather than a checklist or a points scheme – is that it describes quality, not just whether something is present.

How does it work?

The details vary, but most rubrics are built from the same elements:

• Criteria – the aspects of the work being assessed. They are usually derived from the course’s learning outcomes or built on a taxonomy such as SOLO or Bloom’s, with criteria such as account, analysis, application, theorising, presentation, conclusion or mastery.
• Performance levels – usually three to five steps, describing how much evidence the work shows for each criterion, or to what degree the student masters it.
• Descriptors – short descriptions of what the work looks like at each level of each criterion.
• Scoring and weighting – points per level, and sometimes a weighting per criterion, which together produce a score or grade.

Rubrics come in two main types. An analytic rubric assesses each criterion separately, which makes it well suited to feedback. A holistic rubric makes one overall judgement, which is quicker but says less about where the student did well or less well.

Why do institutions use rubrics?

The main reason is consistency and transparency. Because the criteria are anchored in learning outcomes and taxonomies, a rubric links the assessment directly to what the course set out to teach – often called constructive alignment. When several markers assess the same exam, a shared rubric helps them apply the same standards. When a grade is questioned, the rubric shows how it was reached – which makes rubrics a natural basis for grade justification.

Rubrics also support learning. Shared with students in advance, they make expectations explicit and help students plan, check and improve their own work. A 2018 review of 46 studies in higher education found that rubrics were generally associated with positive outcomes – though the quality of the criteria mattered a great deal.

What a rubric cannot do

A rubric is only as good as its criteria. Criteria that only check whether something is present – “uses three sources”, for example – can steer students towards ticking boxes rather than doing good work. Descriptors that are vague, or that simply repeat “good”, “very good” and “excellent”, give markers and students little to go on.

A rubric also does not replace academic judgement. Markers still need to interpret the descriptors and apply them to work that rarely fits neatly into one box. And if a rubric is only used for marking and never shared with students, much of its value for learning is lost.

How does WISEflow approach it?

In WISEflow, rubrics are part of the marking process, not an add-on. Our understanding goes a little further than the grid itself:

• Simple or flexible. A standard rubric is a quick grid of criteria and levels; a custom rubric allows analytic or holistic designs, different scoring per criterion and room for feedback.
• From rubric to grade. Scores can be converted to the institution’s grading scale, so the rubric produces a grade directly.
• Built for teams of markers. Rubrics can be shared and reused, and in rubric-based marking different markers can each assess their own part of an exam, with scores combined into a final grade.
• A clear basis for justification. Because each criterion is assessed and documented, the rubric gives every grade a structured explanation – and a structure for AI-assisted feedback to build on.
• The marker decides. The rubric supports academic judgement; it never replaces it.

What should institutions consider?

• Criteria first: start from the learning outcomes and a shared taxonomy, and describe quality rather than quantity.
• Calibration: let markers try the rubric on sample work before marking begins.
• Students: share the rubric in advance, and use it in teaching, not only in marking.
• Review: revise the rubric after each use, based on how well it worked.

A rubric is not a substitute for expertise. Used well, as part of a considered approach to assessment, it makes standards visible – to markers and students alike.
