Overview: 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. The raw rubric score is calculated as a sum of all criteria grades. The final grade is calculated by comparing the actual score with the worst/best possible score that could be received.
