Weighting is an optional feature you may enable in School Loop's gradebook. Since weighting requires the use of categories, you should first create the categories you plan to use.
1. From any page in your portal, click the Settings link (the gear icon) near the top right of the page.
2. Select one of your gradebooks from the Gradebook Settings section of the next page.
3. Click the Go button for Weighting.
4. Enable weighting by clicking "Yes".
5. Enter the weighted value for each category.
- Use 0 for categories you do not wish to use for this gradebook
- Make sure the sum off all weights is exactly 100%
6. Optional: Choose an extra credit category and set the max extra credit percent.
- See below for an explanation of how this feature works
7. Click the Submit button.
Extra Credit and Weighting
For those who choose to this optional feature with weighting...
1. Choose a category to be used with all extra credit assignments
- Must be a non-weighted category
- We suggest your create a category called "Extra Credit"
2. Set the extra credit percent.
When using this feature, students cannot exceed the maximum extra credit percentage. For example. if you set the max extra credit to 4%, the maximum boost a student can receive is 4%. For more details, see our help page about extra credit.
How weighting is used to calculate grades is not always clearly understood by students and parents. This explanation should be helpful. In the example, there are three weighted categories: Homework, Tests, and Final. Each is weighted 30%, 50%, and 20% respectively.
The figure above illustrates that a student's averages for the Homework and Tests categories are 60% and 70% respectively. Since there is no score for the final exam, that category will not be used in calculating the student's average.
The weight of each category used is multiplied by the student's average for that category. Those products are summed together and divided by the total of the weighted categories in use (80% as pictured above). In this example, the student has earned 53% of a possible 80% for an average of 66.25%. How that percent grade converts to a letter grade is based on your grading scale.
Q: How can a student's grade go down when they get a high score on an assignment?
A: Remember that grades are weighted by category. So if the score on the assignment is lower than the average for that category, the overall grade will go down.
Example: A student’s current overall grade is 90% for all categories (tests, homework, etc.) and they get a 92% on the next test, intuition tells us that their grade should go up. However if their test average is 95% then the weighted average for the Tests category will go down and therefore their overall grade will go down as well.
Q: My student received 100% on an assignment and their grade went down - how is that possible?
A: The student had over 100% in that category, most likely due to extra credit.
Example: A student has turned in all of their homework and has some extra credit points, putting their average for the category at 110%. Now they turn in another homework assignment receiving 100% for that assignment. Their weighted average for the Homework category will go down because 100% is less than 110%.
Q: My student did some additional extra credit but their grade went down. Shouldn't extra credit always raise their grade?
A: Not necessarily. When using the optional extra credit feature within weighting, adding a new extra credit assignment will change the total points possible in the extra credit category and could lower the student’s percentage in that category.
Example: The extra credit category is set to give a student a 5% boost in their grade. So far the student has scored 10/10 on the one extra credit assignment giving them 100% in the extra credit category, and therefore boosting their grade the full 5%. Now you assign another extra credit assignment worth 20 points and the student earns only 5/20. Her total for the extra credit category is now 15/30 or 50%. Her boost has now gone down to 2.5%.
Q: My students are showing averages over 100% but I have not given any extra credit points?
A: Check your Extra Credit setup. The Extra Credit category cannot be one of the weighted categories. Change the Extra Credit category to a non-weighted category. If you are not assigning extra credit assignments, set the Extra Credit category to "None".
