How do I create a Grade item which deducts points?

You will learn how to create a grade item which deducts points from a given category which will affect the Course total for the students. For example, some instructors like to deduct points for attendance or tardiness or a late submission.

Follow these steps to add a Grade item which deducts points rather than adding points to a student's score. Read this article to learn how to create a basic gradebook.

Note: This is a rather complex process, so you may want to consult with the Online Education and Training department for assistance or to verify that you have set up your gradebook correctly.

1. View your syllabus.

In this sample syllabus there is a substantial possible deduction for attendance/tardiness.

View your syllabus.

2. Click on Grades.

Click on Grades.

3. The Grader report page displays all of the Grade items and student names.

The Grader report page displays as the default entry point into the gradebook for instructors. The Grader report page is similar to a spreadsheet showing all of the student names and the Grade items for your course. Students will only see the User report page which shows only their own grades.

6. The Categories and items page will display.

The Categories and items page is where you add and organize Grade items and Categories (folders of Grade items). You can also create custom calculations and choose various methods of aggregating Grade items.

There are some requirements involved in creating a grade item that can deduct points:

  • That grade item must be in a category within the gradebook which uses a customized sum formula (for example: =sum([[1]],[[2]],[[3]],[[4]]) ) to add the grade items
  • The chosen category must have no more than 8 grade items
  • The chosen category must have at least an equal number of points as the grade item which can deduct points
  • The chosen category cannot have any special conditions, like extra credit, drop the lowest, etc.
The Categories and items page will display.

7.1. Click on Add category.

I need to change a number for an item's ID number, but it's locked. How do I unlock it and change its ID number? Please let me know. Thank you.

There are two basic types of grade items in the gradebook: Activities added via the course main page and Grade items added via the Gradebook settings page. If you have added ID numbers to some of your grade items or categories and you want to then change one, you need to check which type of item it is. For Activities added via the course main page, you need to click on the Activity name, click on Edit settings, then scroll down to the Common module settings section where you can retype the ID number.

For Grade items which you added within the Gradebook settings page, click on the Edit link to the right of the category's aggregation method you want to change.

For most users, it is easier to not use a custom calculation for a category, like the Course total, but instead the Natural aggregation method or the Weighted mean of grades method. It is all too easy for newer users to mistype a custom calculation and thereby not obtain satisfactory results which then upsets students.
