# Rubrics

Moodle 2.2 **Rubrics** are advanced grading forms used for criteria-based assessment. The rubric consists of a set of criteria. For each criterion, several descriptive levels are provided. A numerical grade is assigned to each of these levels. The rater chooses which level answers/describes the given criterion best.

## Grade calculation

The rubric normalized score (ie basically a percentage grade) is calculated as

- where is the number of points given to the i-th criterion, is the minimal possible number of points for of the i-th criterion, is the maximal possible number of points for the i-th criterion and is the number of criteria in the rubric.

Example of a single criterion can be: *Overall quality of the paper* with the levels *5 - An excellent paper*, *3 - A mediocre paper*, *0 - A weak paper* (the number represent the number of points).

*Example:* let us have an assessment form with two criteria, which both have four levels 1, 2, 3, 4. The teacher chooses level with 2 points for the first criterion and 3 points for the second criterion. Then the normalized score is:

Note that this calculation may be different from how you intuitively use rubric. For example, when the teacher in the previous example chose both levels with 1 point, the plain sum would be 2 points. But that is actually the lowest possible score so it maps to the grade 0 in Moodle. To avoid confusion, it is recommended to always include a level with 0 points in the rubric definition.
