 +====== PT GradeBook ======
 +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.  ​
 + 
 +
 +===== Final Grade Calculations =====
 +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"​.
 +
 +
 +^ Assignment Name ^ Date ^ Possible ^ Score ^ Category ^
 +|Quiz One|1/​25|30|26| Quiz|
 +|Book Research|1/​25|100|95| Homework|
 +|Quiz Two|2/​1|30|10| Quiz|
 +|Social Behavior Essay|2/​5|150|130| Homework|
 +|Test Chap. 1 - 7|2/​8|300|260| Tests|
 +| |  |610|521| | *Totals |
 +
 +
 +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 ^
 +|Quiz|36|60|=|60|
 +|Homework|225|250|=|90|
 +|Tests|260|300|=|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 ^ ^  ^
 +|Quiz|60|.3|=|18|
 +|Homework|90|.2|=|18|
 +|Tests|86.7|.5|=|43.45|
 +
 +=== Step Four ===
 +
 +PT GradeBook now adds the total scores together. ​ This will give the student the appropriate letter grade depending on the grade scale.
 +
 +^ 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.
 +
 +==== Additional Information ​ ====
 +
 +If there is a category that figures into the final grade setup but there are no assignments in that category, the calculation could be incorrect. ​ To workaround this create all the categories you’ll need, but don’t use them in figuring the Final Grades Setup until you actually have an assignment to put into that category.
