### Site Tools

PT GradeBook is the software application teachers use to track classes, enrollments, attendance, and grades. It interacts with the PowerSchool server automatically sending, and receiving information from the server.

The teacher does have some ability to adjust how a grade is calculated, or how the grade scale is setup. There are a couple options when it comes to the final grade calculation. There are also many factors that come into play as well. We will start with the final grade setup.

### Total Points Scale

The default setting in PT GradeBook is the Total Points Scale. Below is an example student with some scores earned during a term.

 Assignment Name Date Possible Score Quiz One 1/25 30 26 Book Research 1/25 100 95 Quiz Two 2/1 30 10 Social Behavior Essay 2/5 150 130 Test Chap. 1 - 7 2/8 300 260 610 521 *Totals

In this example, the student earned 521 out of a possible 610. So their score is calculated like this: 521 divided by 610 to equal .8403… Just drop the period and round to the nearest number, for a grade of 84%.

The total points scale is just that, the total points earned divided by the possible points. It is the simplest and quickest way to calculate a grade.

### Weighted Grade Scale or Category Weighting

Weighted Grade Scale, or Category Weighting is calculated differently. It isn't as simple as the total points scale, and can be a little confusing at first. For this example, we are going to use the same assignments from the previous example, but I added a new column called “Category”.

In this example, the teacher decided to calculate the final grade using the following allocations:

• Tests: 50%
• Quizzes: 30%
• Homework: 20%

### Calculation Step by Step

PT GradeBook takes additional steps to figure out the weighted final grade. We are going to break down each step to help you understand how it all factors together.

#### Step One

PT GradeBook figures each category separately totaling the points received on assignments in that category. Using the example above, this is what it would look like:

Quiz Category

 Assignment Possible Score Quiz One 30 26 Quiz Two 30 10 60 36 *Totals

Homework Category

 Assignment Possible Score Book Research 100 95 Social Behavior Essay 150 130 250 225 *Totals

Tests Category

 Assignment Possible Score Test Chap. 1 - 7 300 260 300 260 *Totals

#### Step Two

PT GradeBook now divides the total points earned, by the total possible points, to equal a percentage. Using the information above, it would look like this:

Category Score Possible Percent
Quiz3660=60
Homework225250=90
Tests260300=86.7

#### Step Three

PT GradeBook now multiplies the student’s final percent in each category by the percent it factors into the final grade.

Category Percent FG Percent
Quiz60.3=18
Homework90.2=18
Tests86.7.5=43.45

#### Step Four

 Category Category Total Quiz 18 Homework 18 Tests 43.45 79.45 Final Grade

Using the Weighted Grade Scale this student earned a 79.45 percent.
