A scale can be used for non-numeric grading and is defined by an ordered list of values.
Example: Very Poor, Fair, Good, Excellent
All new Moodle sites come with several pre-existing scales. If the existing scales do not suit your needs, you may create your own scales. Scales within your course site may be applied to any activity that uses grading.
WARNING: The Moodle gradebook cannot add any items graded with a scale to a course total. You may see a numeric value for some scales in the gradebook, such as 4 or 5. Those numbers only represent that the scale has 4 or 5 descriptors associated with it.
