Gradebook Setup - Calculations
Note: For information on Grade Plan Grade formulas, see School Year Setup . For GPA calculations, see Create Grade Calculations & Rank.
When setting up their Gradebook, teachers have three options for the Gradebook Calculation method. They are:
Total Points:
In this calculation method, the students' cumulative grade is based on the total points earned divided by the total points attempted. Select this option if the cumulative grade is based on straight points, and you do not take into account the type of assignment when calculating the grade.
-
Formula
sum(assignment grade * assignment factor) / sum(maximum points * factor) = Total cumulative grade
Calculation Example
A class has five total assignments, one of which is an extra credit (EC) assignment. Each assignment is worth 4 points, and each has a factor of 1. The students receives the full 4 points on all regular assignments, and 3 points on the extra credit assignment.
Tip: Factor references if an assignment should count more than once. For example, if an assignment has a factor of 2. In the calculation, the total points for the assignment will be multiplied by 2.
To calculate the total cumulative grade for the class, we must first add up the total points the student earned for all assignment types, multiplied by the assignment factor.
Assignment 1: 4 * 1 = 4
Assignment 2: 4 * 1 = 4
Assignment 3: 4 * 1 = 4
Assignment 4: 4 * 1 = 4
Assignment 5 (EC): 3 * 1 = 3
Total = 19
Then sum up all the assignment maximum point values multiplied by the assignment factor, excluding any extra credit assignments.
Assignment 1: 4 * 1 = 4
Assignment 2: 4 * 1 = 4
Assignment 3: 4 * 1 = 4
Assignment 4: 4 * 1 = 4
Total = 16
Next, divide the sum of the points earned by the sum of the maximum points.
This is your cumulative grade.
19 / 16 = 1.1875
118.75%
Total Points with Weight:
In this calculation method, the students' cumulative grade is based on the total points a student earned, divided by the total points attempted within each assignment type. The assignment type grades are then averaged together based on their weights. Select this option if the cumulative grade is based on something like 30% homework, 40% quizzes, and 30% exams, but each assignment within those categories is worth varying points.
-
Formula
For each assignment type: sum(assignment grade * assignment factor) / sum(maximum points * factor) = Assignment type grade
Then: sum(assignment type grade * weight) / sum(weight) * 100 = Total cumulative grade
Tip: To view a student's grade for each assignment type from the gradebook, select the dropdown at the end of the student's name, then select See student's gradebook.
Calculation Example
A class has five total assignments and one extra credit (EC) assignment. Each assignment is worth 4 points, and each has a factor of 1. The students receives the full 4 points on all regular assignments, and 3 points on the extra credit assignment.
To calculate the total cumulative grade for the class, we must first calculate the assignment type grade.
For each assignment, divide the assignment grade by the assignment factor.
Add the sums together.
Assignment 1: 4 * 1 = 4
Assignment 2: 4 * 1 = 4
Assignment 3: 4 * 1 = 4
Assignment 4: 4 * 1 = 4
Assignment 5 (EC): 3 * 1 = 3
Total = 19
Then sum up all the assignment maximum point values multiplied by the assignment factor, excluding any extra credit assignments.
Assignment 1: 4 * 1 = 4
Assignment 2: 4 * 1 = 4
Assignment 3: 4 * 1 = 4
Assignment 4: 4 * 1 = 4
Total = 16
Next, divide the sum of the points earned by the sum of the maximum points. This is your assignment type grade.
19 / 16 = 1.1875
Apply weights to each assignment type grade by multiplying each assignment type grade by it's weight.
Homework: 1.1875
Weight: 50%
1.1875 * 0.50 = 0.5938
Classwork: 0.9102
Weight: 50%
0.9102 * 0.50 = 0.4551
Add all the weighted grades together, and divide by the sum of the weights. Multiply by 100.
This is your cumulative grade.
Assignment type grades: 0.5938 + 0.4551 = 1.0489
Weights: 0.5 + 0.5 = 1
1.0489 / 1 = 1.0489
104.89%
Percentages:
The assignments are averaged together within each assignment category, the average is used to calculate the cumulative grade based on the weights the
-
Formula
For each assignment type: sum(assignment grade / maximum points * assignment factor) / sum(factor) = Assignment type grade
Then: sum(assignment type grade * weight) / sum(weight) * 100 = Total cumulative grade
Tip: To view a student's grade for each assignment type from the gradebook, select the dropdown at the end of the student's name, then select See student's gradebook.

To calculate the total cumulative grade for the class, we must first calculate the assignment type grade.

Add the sums together.
Assignment 1: (4 / 4 * 1) = 1
Assignment 2: (4 / 4 *1 ) = 1
Assignment 3: (4 / 4 * 1) = 1
Assignment 4: (4 / 4 * 1) = 1
Assignment 5 (EC): (3 / 4 * 1 ) = .75
Total = 4.75
Then sum up all the assignment factors, excluding any extra credit assignments.
Assignment 1: 1
Assignment 2: 1
Assignment 3: 1
Assignment 4: 1
Total = 4
Next, divide the assignment averages by the sum of the factors. This is your assignment type grade.
4.75 / 4 = 1.1875
Apply weights to each assignment type grade by multiplying each assignment type grade by it's weight.
