What is Grading Schema?  

In the Grade Center, numeric grades appear by default. A schema takes the points scored on an item and compares it to the item's total points possible to derive a percentage. This percentage is mapped to a range of scores and displays a grade, such as a letter (A, B, C) or Pass/Fail. Grading Schema information is presented in a table format.

Grading Schema Menu

The Grade Center includes a copy of a default grading schema based on assigning letters to the percentages. Your institution may edit this schema to reflect a general grading schema used for all courses. TIP: You can make the uppermost value in a grading schema greater than 100%.
