What Is the 4.0 GPA Scale?
The Infinite Campus 4.0 GPA scale is the system that converts your letter grades into numerical grade point values. Every letter grade maps to a specific number on a 0.0–4.0 range, and your GPA is the weighted or unweighted average of those points across all courses. This single number is one of the most important metrics colleges, scholarship providers, and honor societies use to evaluate your academic performance.
Key fact:
The 4.0 scale is used by virtually every U.S. high school and college. On Infinite Campus, your GPA is calculated automatically based on the letter grades in your transcript — but whether it's weighted or unweighted depends on your district's configuration.
The Standard 10-Point A–F Grading Scale
The most widely used Infinite Campus grading scale across U.S. districts is the standard 10-point scale. Each letter grade covers an equal 10-percentage-point range:
| Letter Grade | Percentage Range | GPA Points | Meaning |
|---|---|---|---|
| A | 90 – 100% | 4.0 | Excellent |
| B | 80 – 89% | 3.0 | Good |
| C | 70 – 79% | 2.0 | Average |
| D | 60 – 69% | 1.0 | Below Average |
| F | 0 – 59% | 0.0 | Failing |
This scale is the default in many Infinite Campus districts. Its simplicity makes it easy to understand: each 10% increment moves you one full letter grade.
Plus/Minus Grading Scale
Many districts and teachers add plus (+) and minus (–) modifiers for more granular grading. This is the second-most common Infinite Campus grading scale configuration:
| Letter | Range | GPA |
|---|---|---|
| A+ | 97 – 100% | 4.0 |
| A | 93 – 96% | 4.0 |
| A– | 90 – 92% | 3.7 |
| B+ | 87 – 89% | 3.3 |
| B | 83 – 86% | 3.0 |
| B– | 80 – 82% | 2.7 |
| C+ | 77 – 79% | 2.3 |
| C | 73 – 76% | 2.0 |
| C– | 70 – 72% | 1.7 |
| D+ | 67 – 69% | 1.3 |
| D | 63 – 66% | 1.0 |
| D– | 60 – 62% | 0.7 |
| F | 0 – 59% | 0.0 |
Why Plus/Minus Matters
Under the standard 10-point scale, an 89% and an 80% are the same B. With plus/minus, that 89% becomes a B+ (3.3 GPA) while the 80% is a B– (2.7 GPA). Over a full course load, this 0.6 GPA-point difference per class can significantly impact your cumulative GPA.
The 7-Point Grading Scale
Some districts — particularly in states like Georgia and parts of the Southeast — use a 7-point grading scale with narrower ranges. This is a stricter system where higher percentages are required for each letter grade:

10-Point Scale
- A: 90 – 100%
- B: 80 – 89%
- C: 70 – 79%
- D: 60 – 69%
- F: Below 60%
Most common nationwide
7-Point Scale
- A: 93 – 100%
- B: 85 – 92%
- C: 77 – 84%
- D: 70 – 76%
- F: Below 70%
Common in the Southeast U.S.
An 84% is a solid B on the 10-point scale but only a C on the 7-point scale. If your district uses a 7-point scale on Infinite Campus, you'll need to adjust your grade targets accordingly. Try our Grade Predictor to see what scores you need.
District Variations & Custom Scales
One of the most important things to understand about the Infinite Campus grading scale is that it's fully customizable at the district level. Here are real examples of how scales can differ:
Equalized 100–50 Scale
Some districts compress the F range so the lowest possible score is 50% instead of 0%. This prevents a single zero from devastating a student's grade. Under this model, a missing assignment earns 50% rather than 0%.
Standards-Based Grading (1–4 Scale)
Elementary and some middle schools use a proficiency scale: 4 = Exceeds Standard, 3 = Meets Standard, 2 = Approaching Standard, 1 = Below Standard. IC fully supports this as an alternative to traditional A–F grading.
AP/Honors Modified Scales
Teachers of AP or Honors classes may use stricter cutoffs (e.g., 95% for an A) or may add GPA weight (+1.0 for AP, +0.5 for Honors) while using the standard percentage scale. Both approaches can be configured in IC.
Pass/Fail (P/F)
Certain electives or courses may use a simple Pass/Fail scale where any grade at or above the passing threshold (typically 60% or 70%) earns a P. This is common for student teaching, internships, and some PE classes.
How Infinite Campus Applies the Grading Scale
Understanding the mechanics helps you predict your letter grade from your percentage. Here's the step-by-step process IC uses:
- 1. Calculate your numerical percentage using the teacher's chosen method (weighted categories, total points, or another IC calculation method).
- 2. Apply rounding rules if the district has enabled rounding (e.g., 89.5% rounds to 90%).
- 3. Match to the grading scale by finding the grade where your percentage falls at or above the minimum cutoff.
- 4. Display the letter grade alongside your percentage in the student portal and on report cards.
Rounding Rules & Edge Cases
Rounding is one of the most common sources of confusion with the Infinite Campus grading scale. Whether your 89.5% rounds up to an A or stays a B depends entirely on your district's configuration:
Rounding Enabled
- 89.5% ? rounds to 90% ? A
- 79.5% ? rounds to 80% ? B
- The teacher sets the minimum cutoff with a .5 threshold (e.g., 89.5 for A)
Rounding Disabled
- 89.99% ? stays at 89% ? B+
- 79.99% ? stays at 79% ? C+
- You must actually reach the cutoff percentage — no exceptions

How to Find Your District's Grading Scale
Since every district can configure the Infinite Campus grading scale differently, it's important to confirm what scale your classes use:
1. Check the Student Portal
Log into Infinite Campus and open your class gradebook. Some configurations show the grading scale directly alongside your percentage and letter grade.
2. Read the Course Syllabus
Most teachers include their grading scale in the syllabus handed out at the start of the semester. Look for a section labeled "Grading Policy" or "Grade Scale."
3. Visit Your District Website
Many districts publish their official grading scale in the student handbook or academic policy section of their website. Search for "[your district name] grading scale."
4. Ask Your Teacher
When in doubt, ask directly. Your teacher can confirm the exact cutoffs configured in their IC gradebook and whether rounding is enabled.
How Your Grading Scale Affects Your GPA
The grading scale your district uses directly impacts your GPA. Consider how a student earning 91% in every class fares under different scales:
| Scale Type | 91% Earns | GPA Points |
|---|---|---|
| 10-Point (no +/–) | A | 4.0 |
| Plus/Minus (93 for A) | A– | 3.7 |
| 7-Point (93 for A) | B | 3.0 |
That same 91% ranges from a 4.0 to a 3.0 depending on the scale — a full GPA point of difference. Calculate your actual GPA using our Infinite Campus GPA Calculator or Cumulative GPA Calculator.

Frequently Asked Questions
What grading scale does Infinite Campus use?
Infinite Campus does not use a single fixed grading scale. Each district — and sometimes each teacher — configures their own. The most common is the 10-point scale (A = 90–100), but plus/minus scales and 7-point scales are also widely used.
Can different teachers use different grading scales?
Yes. While districts typically set a default scale, Infinite Campus allows individual teachers to select or create their own. An AP teacher might require 93% for an A while a standard-level teacher in the same building uses 90%.
How do I find my school's grading scale?
Check the IC student portal, your course syllabus, or your district's website. You can also ask your teacher directly — they can see the exact configuration in their gradebook settings.
Does Infinite Campus round grades up?
It depends. IC supports rounding, but it must be enabled in the grading scale settings. Some districts round at .5 (so 89.5 becomes 90%), others don't round at all. Check your teacher's policy to know for sure.
What is the difference between a 10-point and 7-point scale?
A 10-point scale uses 10-percentage-point ranges per letter grade (A = 90–100). A 7-point scale uses narrower ranges (A = 93–100), so you need higher scores for the same letter grade. Both can be configured in Infinite Campus.
