Rubrics can be scored in two ways:

- Raw Scores
- Scaled Scores

## Raw Scoring

In raw scoring, the maximum number of points a Rubric could be worth is calculated as Number-of-Categories * Highest-Value.

For example, if there are 4 Criteria (i.e. rows) and the highest value is four, then the maximum value for the Rubric - the maximum possible score - will be 4 * 4 or 16.

A student's score then becomes how many points do they get out of the 16 available, or "Actual Points"/16.

Here's how this works overall:

- An Assignment is created by selecting a Rubric as it's "Grading Type".
- The Maximum possible score for the Rubric is used as the "Maximum Score" for the Assignment
- The student is graded and earns up to the maximum points available (the "Maximum Score" for the Rubric.
- The computation is "Actual Points Received" / Maximum Possible Score. This is treated as a percentage: ("Actual Points Received" / Maximum Possible Score) * 100.
- The % of points that they earned is their grade for the Assignment.

The problem with this type of scoring is that the % if earned points is generally quite a low number, percentage wise.

For example, if a student earns 12 out of 16 points, they only score 75%.

## Scaled Scoring

In scaled scoring, instead of using the raw percentage of points earned as the score for the Assignment, the raw percentage is first calculated and then converted - scaled - to a different and generally higher score.

Here's how it works: First, the "scale" is created in the Rubric:

- A set of "Grades" are created. Each "Grade" has a name or label (e.g. "Advanced"), a starting low average Row score and a "thru" or high Average Row score.
- Each range of low to high average row scores is mapped to a percentage.
- The "percentage" is used as the actual grade for the Assignments using the rubric.
- The Assignment has a "maximum possible points" that is completely separate from the Rubric. A student's final score for the Assignment is the
**selected**percentage of the Maximum Possible Score for the Assignment.

In the example used above, if a student's average row score was 3.7, the grade of "Advanced" would be selected, and the grade converted to a percentage of 75%.

The student then gets 75% of the maximum possible score (which, in this case, is not that great a grade).

In scaled scoring, the teacher (or the Rubric designer) determines what the "scale" is going to be.

In raw scoring, the grade is the grade, there is no "conversion" step.
