Body
An alternative to giving numerical grades on an assignment is to use Grading scales. For example, you could use a custom scale when you want students to see Excellent, Good, or Fair as a grade on an assignment as opposed to a numerical score.
Grading scales are best for record-keeping purposes and other assessments you do not intend to factor into the course total in your Moodle gradebook. However, keep in mind that Moodle still assigns numerical values to each term within the scale in order to do mathematical operations (see below). Depending on your gradebook setup, these values can impact your grade calculations in ways you may not intend.

Standard Grading Scales
Moodle at UMass Amherst provides the following standard grading scales:
- Separate and Connected ways of knowing: Mostly separate knowing, Separate and connected, Mostly connected knowing
- Satisfactory: Not satisfactory, Satisfactory, Outstanding
- Received: Not received, Received
- Excellent/Very poor (5 points): *Very poor, **, ***, ****, ***** Excellent
How Grading Scales Work
The aggregation method used with Scales affects scores. While you and your students will see the values assigned by a grading scale in the Grader report and User report, these values will function numerically in grade book calculations depending on the kind of grade calculation being used.
- Natural: The first value in the scale is given the value of 1, and subsequent values are assigned the next whole number (e.g. "Very Poor" = 1, "Poor" = 2, "Fair" = 3, "Good" = 4, "Excellent" = 5).
- Mean of grades or Custom weights: The first value in the scale is given the value of 0, and subsequent values are assigned the next whole number (e.g. "Very Poor" = 0, "Poor" = 1, "Fair" = 2, "Good" = 3, "Excellent" = 4).
Using Scales to replicate a standard letter scale is not recommended:
While you could create a conventional letter scale using a custom scale, doing so may have unexpected effects on grade calculation because of the way each letter is assigned a numerical value (see below).
F (1), D (2), D+ (3), C- (4), C (5), C+ (6), B- (7), B (8), B+ (9), A- (10), A (11)
When using a custom scale like this instance, calculating a grade percentage will not align with the traditional letter scale. For instance, a C on the scale above would be equivalent to 45% (5 / 11). If you want to see grades in your gradebook displayed as letter grades, it may be simpler to edit the category settings and change the display mode.
Set a Scale Grade Item to Not Aggregate
Any grade item on the gradebook can be set to not aggregate in the calculation of the grade book. To set a scale grade item to not aggregate:
- Select Course Management, the Course Management panel will open.
- On the Course Management panel, under Grading, select Gradebook setup. The Gradebook setup page will open.
- Locate the row for the grade item you wish to edit, go to the Weights column and change the value to '0'.
Note: This option will not be available if using the Mean of grades aggregation method.
Note: If using the Natural aggregation method, click the checkbox next to the weight to enable edits of the weight column.
- Click Save Changes when complete.
Create a Custom Grading Scale
To create a custom grading scale:
- Select Course Management (black gear icon, top right), the Course Management panel will open.
- On the Course Management panel, under Grading, select Gradebook setup. The Gradebook setup page will open.
- In the navigation tabs, click Scales. The Course scales page will open.
- At the bottom of the page, click Add a new scale. The Add a scale page will open.
- Type a name for your scale in the Name box.
- Enter the actual terms of your scale in order from least to greatest, separated by commas (e.g. "Very Poor, Poor, Fair, Good, Excellent").
- (Optional) Enter a description for your scale.
- Click Save Changes when complete.
Apply a Scale to a Grade Item or Category Total
After creating a custom scale, it can be used with a grade item or category total by editing advanced settings. Note: The scale for an activity-based grade item is set on the activity settings page.
- Select Course Management (black gear icon, top right), the Course Management panel will open.
- On the Course Management panel, under Grading, select Gradebook setup. The Gradebook setup page will open.
- Under Actions, in the row for a grade item or category title click Edit. The Edit page for this item will open.
- On the Edit page, click to the Grade item or Category total heading to view and adjust the settings.
- In the Grade type drop-down menu, select Scale. (If you do not see this option, click Show more... to view all options)
- In the Scale drop-down menu, select the name of the scale.
- Scroll to the bottom of the page and click Save changes.
