PowerSchool grade calculator
PowerSchool’s teacher gradebook, PowerTeacher Pro, works out a term grade by total points (points earned divided by points possible) or by category weighting, where each category percent is rounded to a whole number and then multiplied by its weight. A semester grade such as S1 then comes from term weighting, for example Q1 at 40%, Q2 at 40% and the exam at 20%. Your district sets the weights, so enter yours below. The math runs in your browser and nothing you type is sent anywhere.

How does PowerSchool calculate grades?
Your teacher picks a calculation type for each reporting term on the Traditional Grade Calculations page of PowerTeacher Pro. The district can set a default and lock it. PowerSchool documents these types, and a term can mix them:
| Type | What PowerSchool does | In this calculator |
|---|---|---|
| Total points | Points earned for the class divided by points possible. PowerSchool’s example: 1,250 of 1,600 points is 78%. | Choose Total points. Category weights are ignored. |
| Category weighting | Each category’s percent, rounded, times its weight. The weighted values are added up. | Choose Category weighting and enter each weight. |
| Term weighting | A longer term’s grade from shorter terms, such as S1 from Q1 and Q2. | The second calculator, below the first. |
| Standards weighting | A course grade from the standards grades aligned to it. | Not modeled. Standards grades use their own scales. |
| Mixed weighting | Several types in one term, averaged by their weights. PowerSchool warns that scores can be counted twice. | Not modeled. |
Weights are relative. PowerTeacher Pro shows a Percent column next to the weights and asks teachers to use weights that make those percents add up to 100%. A category left out of the formula does not count at all. If your class page shows no overall grade, your teacher may not have ticked Calculate Overall Class Grade for that term.

Why are my PowerSchool category percents rounded?
Because PowerTeacher Pro rounds them on purpose. Its documentation says: “When you calculate the Category Weighting Grade, the decimal points of percentages are rounded, regardless of the setting to calculate to two decimal places.” So a quiz category at 87.5% counts as 88%, and one at 84.4% counts as 84%, before the weights are applied.
The effect is small but real. It can move a grade that sits near a cutoff to the other side. The calculator rounds the same way, and when the rounding changes your term grade it tells you what the grade would be without it. Total points grades are not rounded this way, because there are no category percents in the calculation.
How do Q1, Q2 and the exam make S1 in PowerSchool?
Through term weighting. PowerSchool’s own example calculates the S1 grade from the final grades for Q1 and Q2, with 40% for Q1 and 60% for Q2. Schools can add an exam term to the formula. A Nova Scotia guide for PowerTeacher Pro gives an example that calculates F1 (the final grade) from S1 at 70% and E1 at 30%. Your district decides which terms count and how much, so copy the weights from your syllabus or ask your teacher.
Term weighting has two options. With Exact Value Earned, the calculation uses the percent you earned in each shorter term. With Term Weighting Points, each term’s grade is first turned into the points your district’s grade scale assigns to it. This calculator uses the exact value. If your school uses term weighting points, an A in a term counts as the same number whether it was 91% or 99%, so your semester grade can differ from what you see here.
To work out what you need on the exam, enter your term percents, leave the exam blank and pick it in “Work out what I need on.” The calculator solves for the exam score that brings the semester to your target, and tells you if even 100% falls short.

What is the minimum assignment value in PowerSchool?
It is an optional floor that a district administrator can turn on. When it is on, “the system automatically adjusts any assignment score lower than the minimum value to the minimum value.” With a 50% minimum, a 2 out of 10 is recorded as 5 out of 10. It applies to scores typed in, imported or received from other systems. Turning it off later does not change scores that were already raised.
If your school uses one, enter it in the calculator and every score below it is raised the same way. If you are not sure, leave it blank. Your scores on the class page already show any adjustment.

A worked example
Three weighted categories for Q1. The Load the example buttons put these numbers into both calculators.
| Category (weight) | Scores | Percent | Counts as |
|---|---|---|---|
| Homework (20) | 18/20, 9/10, 7/10 | 34/40 = 85% | 85 |
| Quizzes (30) | 17/20, 18/20 | 35/40 = 87.5% | 88 |
| Tests (50) | 89/100 | 89% | 89 |
Q1 grade: (20 × 85 + 30 × 88 + 50 × 89) ÷ 100 = 87.9%. Without PowerSchool’s rounding it would be 87.75%. Graded by total points instead, the same scores give 158 of 180 points, 87.78%.
For the semester, say Q1 is 87.9%, Q2 is 84% and S1 weights them 40, 40 and 20 with the exam. So far that averages to 85.95%. To finish S1 at 85% you need at least 81.2% on the exam, and a perfect exam would give 88.76%.
Why your PowerSchool grade might not match
- Your district uses different weights. The numbers in the example are made up. Use the weights on your class page or syllabus.
- Low scores are dropped. PowerTeacher Pro has a Drop Low Scores tab for each term. Its documentation does not say whether it drops by percent or by points. This calculator drops the lowest percents.
- A category has no scores yet. PowerSchool’s documentation does not say how an empty category counts. This calculator leaves it out and scales the other weights to fill the gap.
- Secondary categories are on. Some districts let an assignment carry a second category with its own weights inside the first. That layer is not modeled here.
- Exempt, missing or late flags. Exempt work is left out, and a missing flag may or may not count as zero, depending on your school’s setup. Enter the score your class page shows.
- Term weighting points. If your school converts term grades to points before weighting, see the section above.
For a course graded by category weights outside PowerSchool, the weighted grade calculator works the same weighted average without the rounding. The final grade calculator works out a final exam score from one current grade. To turn your class grades into a GPA, the PowerSchool GPA calculator uses PowerSchool’s standard weighted and simple GPA formulas.
Each school gradebook does the math its own way. There are calculators for Infinite Campus, Skyward, Schoology and Google Classroom too.
PowerSchool grade calculator FAQ
How does PowerSchool calculate my grade?
Your teacher picks the method in PowerTeacher Pro. With total points, your grade is the points you earned divided by the points possible. With category weighting, each category percent is rounded to a whole number, multiplied by the category weight, and the results are added up and divided by the total weight.
Does PowerSchool round category grades?
Yes, in category weighting. PowerSchool’s documentation says the decimal points of category percentages are rounded before weighting, even when the class is set to calculate to two decimal places. A category at 87.5% counts as 88%.
How is my semester grade calculated in PowerSchool?
Usually by term weighting: each shorter term, such as Q1, Q2 and an exam term, counts by a weight your district sets. PowerSchool’s example weights Q1 at 40% and Q2 at 60% for S1. Enter your own weights in the second calculator to see your semester grade and what you need on the exam.
What is E1 in PowerSchool?
It is a reporting term code, often an exam term. In a Nova Scotia guide for PowerTeacher Pro, the final grade F1 is calculated from S1 at 70% and E1 at 30%. Term names and weights are set by each district, so check your class page.
What does the minimum assignment value do?
If your district turns it on, PowerSchool raises any score below the minimum to the minimum. With a 50% minimum, a 2 out of 10 counts as 5 out of 10. Enter the minimum in the calculator to apply the same rule.
Does this calculator send or save my grades?
No. The math runs in your browser, and the numbers and names you type are not sent to any server or stored on your device. Close the tab and they are gone. The page itself is counted in our visit statistics, which never include what you type.
