Grade calculations
Grade rounding in the gradebook
Grades for individual items in the gradebook are rounded to the hundredth place.
Overall grades and grading period grades are calculated using unrounded values.
Grading category calculation methods
Each grading category can be calculated using either total points or percentages.
Calculation method | Description |
|---|---|
Total Points | The category grade is the total points earned divided by the total points possible. |
Percentage | The category grade is based on the percentage scores of individual items. |
Overall grade calculation process
When calculating the grading period or overall grade, unrounded values are used to ensure accuracy.
Example calculation
A student has the following grades in two categories.
Category | Weight | Assignments | Category grade calculation | Unrounded value used |
Homework | 50% | 12/13 11/13 | (12 + 11) ÷ 26 × 100 = 88.46% | 88.46153846% |
Quizzes | 50% | 15/17 | 15 ÷ 17 × 100 = 88.24% | 88.23529412% |
Final overall grade calculation
Using unrounded values, the overall grade is calculated as:
(50 × 88.46153846 + 50 ×88.23529412) ÷ (50 + 50)
= 8834.841629 ÷ 100
= 88.35%
This method ensures that rounding does not impact the final grade.
