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.
