# Rubrics

Template: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 is 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:

- <math>G_s = \frac{(2 - 1) + (3 - 1)}{(4 - 1) + (4 - 1)} = \frac{3}{6} = 50 %
