If you cannot find an outcome to use in your course, you can create a new outcome.
Outcomes can be included in assignment rubrics as an easy way to assess mastery of learning objectives. When you create a learning outcome, you should also define a criterion that can be used when building assignment rubrics. Define as many rubric columns as you need, and specify a point threshold that will be used to define mastery of this outcome.
In Course Navigation, click the Outcomes link.
Click the New Outcome button.
Enter a name for the outcome in the Name this outcome field . This is the official name of the outcome that will also appear in the Learning Mastery Gradebook.
If you allow students to view Learning Mastery scores on the Grades page, they will see the name of the outcome. However, you may want to create a custom, friendly name. To create a friendly name for student view, enter a name in the Friendly name (optional) field .
You can also enter a description in the Rich Content Editor field .
Click the Edit icon  to edit the criterion rating. You can change the existing name (if desired) for the criterion in the Criterion Name field . Set the criterion point value by typing in the Points field .
To save the criterion, click the OK button . To remove the criterion completely, click the Delete button .
To add additional criterion ratings, click the Insert link .
Set the mastery point value in the Mastery at field . This field indicates the number of points that must be achieved for mastery according to the criterion ratings.
In the Calculation Method drop-down menu , select the calculation method for the outcome. By default, new outcomes are set to the Decaying Average calculation method in the Canvas interface.
Click the Save button .
You can set one of four calculation methods: Decaying Average, n Number of Times, Most Recent Score, and Highest Score.
Decaying Average: Select this option to average assessment item scores with a greater weight for the most recent assessment item. The Decaying Average calculation splits the total percentage between the most recent assessment item and an average of all prior assessment items. For example, you can set the most recent submission to be weighted at 40% of the total and prior items to be weighted at 60% of the total.
Enter a percentage between 1% and 99% for the most recent item weight. The remaining amount is used to weigh prior scores. The percentage split is set to 65/35 by default. The average is rounded to the next two decimals. If there is only one result, the single score will be displayed.
n Number of Times: Select this option to set a number of times that a student must meet or exceed mastery on a set amount of aligned items. Any scores that do not meet mastery are not used in the calculation. You can specify between 1 and 5 items required for mastery.
Most Recent Score: Select this option to always select the score for the most recent assessment item.
Highest Score: Select this option to always select the highest score for all assessment items.
