Rubrics can be used to evaluate student work based on defined criteria and scales. They are a set of standards linked to the levels of student achievement. Each criterion within a rubric includes a description of the level of achievement and a numeric value can be attached to each criterion.
When marking, rubrics allow the lecturer to select the level the student has achieved against each criterion and add further comments for each. If the numeric grade option is used, the rubric will calculate a total grade for assignment.
The Rubric should be designed using the assessment criteria for a specific module assignment. Guidance on writing effective rubrics, with a checklist for checking your completed rubric is available from Arizona State University, link below.
