Teachers sometimes add extra assignments in courses which may complicate their grading or scaled grading, especially when using Weighting in Gradebooks. This article shares information for teachers to manage extra credit assignments and understand its effect on grading.
Consider this scenario. A teacher using decides to give an extra credit of 5 points for each field trip that students are asked to make in their neighborhoods. Let's go over the following possible approaches the teacher can use to manage this extra credit and learn about the potential issues that may affect the overall grades of students:
Extra Credit without Affecting Grading
Teachers may create extra credit category that is not counted towards the grade. Therefore, the teacher assigns it 0% weight or score, regardless of using weighting in the gradebook. If a student scores ten marks in this extra credit category, they get a score of 10/0 which does not have any effect on their grade.
Extra Credit in Gradebooks not using Weighting
If the class gradebook is set up without Weighting, the teachers may:
- Add a new extra credit category for these field trips by deducting marks from other categories to ensure the total grade is out to 100.
- Or the extra credit can be added in another category, for example, the Quiz category. Where the points awarded will raise the student's average for the Quiz category, increasing their overall g in the class.
Extra Credit in Gradebooks using Weighting
When using weighting in Gradebooks, an optional extra credit feature allows teachers to define the maximum percent boost by the assigned extra credit work. If the teacher observes that the extra credit score is resulting in an overall grade that is greater than 100 for some students, they can reduce the maximum percent boost.
For example, the teacher creates an Extra Credit Trips category for the trips assignment and sets the max extra credit to 5%. Over the term, the teacher asks the students to make ten trips with the total points for all trips becoming 50 ( 5 points for each trip).
Therefore, students who earn all 50 points get the maximum boost of 5% on top of their overall grade. Another student who only accumulated 10 points or 20% of the total extra credit receives a 1% boost to their grade (20% of the 5% max equals one grade point.).
If it is observed that some students are getting the final grade score over 100. The teacher can reduce the max extra credit or make it zero to avoid this discrepancy in the final grading.
Refer to step six when configuring weighted gradebooks to set up Extra Credit category and Max Extra Credit.
Extra Credit with Scaled Grading

Issues When Using Extra Credit
Sometimes the use of extra credit can:
- Increase the overall grades of students beyond 100%.
- Adding extra credit assignment is lowering grades.
