Rubric grading is criterion based. Holistic rubrics require raters to give a single score based on the overall quality of the presentation. This may or may not be used in conjunction with other items. A multi-dimensional rubric can provide a better assessment and understanding of expected or actual performance. Students are fully aware of the content and meaning of the grading rubric.
Rubrics contain an even number of performance levels.
Each level gives a descriptive meaning of the required performance.
