What Are Grade Calc Options in Infinite Campus?
Infinite campus grade calc options are the configuration settings inside the IC teacher gradebook that determine how student grades are calculated. They control everything from whether assignments are grouped into weighted categories to how missing work is handled and whether rounding is applied before letter grades are assigned.
Why this matters:
Two teachers at the same school can produce wildly different grades for the same set of scores simply by choosing different grade calc options. A student with scores of 95, 60, 80, and 90 could have an A under one configuration and a B– under another. Understanding these settings is essential for both teachers and students.
Teachers access these settings through Grade Book > Settings > Grade Calc Options in the IC interface. The options are set per section (class period), so the same teacher can use different configurations for different classes.
The Calculation Method Setting
The single most impactful infinite campus grade calc option is the calculation method. It determines the fundamental formula IC uses to compute grades. There are three primary methods:
Weighted Categories
Each category (Tests, Homework, etc.) is assigned a percentage weight. The final grade is the weighted average of all category averages.
Example: Tests 40%, Homework 20%, Quizzes 25%, Participation 15%

Total Points
Every point is equal. The final grade = total points earned ÷ total points possible. Larger assignments naturally weigh more.
Example: A 100-pt test matters 10× more than a 10-pt homework
Points with Categories
A hybrid: assignments are organized into categories for display, but the actual calculation uses total points (no category weights).
Categories are for organization only — they don't affect the math
The method you choose fundamentally reshapes how every assignment contributes to the final grade. For a detailed comparison, see our Weighted vs Total Points guide.
How Weighted Categories Work
When a teacher selects weighted categories as the grade calc option, they must define categories and assign each a percentage weight that sums to 100%. Here's how IC processes the calculation:
- 1. Calculate each category average — IC sums all earned points within the category and divides by total possible points to get a category percentage.
- 2. Multiply by the category weight — Each category percentage is multiplied by its assigned weight (e.g., 85% × 0.40 = 34 weighted points for a Tests category worth 40%).
- 3. Sum all weighted values — The final grade is the total of all weighted category contributions.
- 4. Handle empty categories — If a category has no graded assignments, IC redistributes its weight proportionally among the remaining categories. This is called weight redistribution.
Weight Redistribution — The Most Confusing Setting
Early in the semester, when only homework has been graded but tests haven't started yet, IC redistributes the test weight across graded categories. This means your homework grade temporarily counts as your entire grade.
This often confuses students who see a high grade early on, then watch it drop once test scores are entered. It's not a bug — it's the weight redistribution feature of the grade calc options. Learn more about this in our Grade Not Matching troubleshooting guide.
Use our Weighted Grade Calculator to model exactly how weighted categories affect your grade with your teacher's specific weight configuration.
Total Points Mode
The total points calc option is the simplest to understand: every point counts equally. IC adds up all points earned across all assignments and divides by all points possible.
| Assignment | Points Possible | Points Earned | Natural Weight |
|---|---|---|---|
| Unit Test | 100 | 85 | 66.7% |
| Homework #1 | 25 | 25 | 16.7% |
| Homework #2 | 25 | 20 | 16.7% |
| Total | 150 | 130 | 86.7% |
Notice how the 100-point test naturally accounts for 66.7% of the grade even though no explicit weights were set. This is why point values matter so much under total points mode. Try our Total Points Calculator to model this for your own classes.
Drop Lowest Score
The drop-lowest-score option allows teachers to automatically exclude a student's lowest score within a specific category. This is one of the most student-friendly grade calc options available:
How It Works
- • Configured per category (e.g., drop lowest quiz only)
- • IC identifies the lowest percentage score in that category
- • That assignment is excluded from both earned and possible points
- • The category average is recalculated without the dropped score
What Students Should Know
- • The dropped score still appears in the gradebook (it's not hidden)
- • As more scores are added, which one is "lowest" may change
- • A missing/zero assignment will always be the one dropped
- • Teachers can drop more than one score (e.g., "drop lowest 2")
Extra Credit Handling
Infinite Campus offers two ways for teachers to set up extra credit through the grade calc options, and the method chosen determines how much extra credit actually helps:
Extra Credit Assignment (0 points possible)
The teacher creates an assignment with 0 points possible but awards points earned. Under total points, those points add directly to the student's total earned without increasing points possible. Under weighted categories, the extra points increase the category average (potentially above 100%).
Extra Credit Category
An entire category dedicated to extra credit. Under weighted categories, the teacher can assign a small weight (e.g., 5%) that adds on top of the other categories, pushing the maximum possible grade above 100%. Under total points, it functions the same as individual extra credit assignments.
Missing & Excluded Assignments
How IC handles ungraded, missing, and excluded assignments is one of the most misunderstood infinite campus grade calc options:
| Status | What It Means | Effect on Grade |
|---|---|---|
| Blank (no score) | Not yet graded | Excluded from calculation entirely |
| Missing (M) | Student did not submit | Treated as 0 points earned, points possible still count |
| Excluded (X) | Teacher removed from calculation | Excluded from calculation entirely (like it doesn't exist) |
| Zero (0) | Graded as zero | 0 points earned, full points possible — maximum grade impact |
Blank vs. Missing vs. Zero:
The difference between a blank score and a zero is enormous. A blank is ignored in the calculation, so your grade stays the same. A zero counts as 0 points earned toward a full assignment's worth of possible points — it actively pulls your grade down. The "Missing" flag also counts as zero. If your grade seems wrong, check for missing flags on ungraded work. See our Grade Not Matching guide for more.
Rounding Options
Rounding is a grade calc option that controls whether IC rounds the calculated percentage before converting it to a letter grade:
Rounding Enabled
- • 89.5% ? rounds to 90% ? A
- • Teacher selects the number of decimal places
- • Rounding applies before the grading scale lookup
- • Can bump students across letter grade boundaries
Rounding Disabled
- • 89.99% ? stays at 89.99% ? B+
- • The raw calculated percentage is used as-is
- • Students must truly earn the cutoff percentage
- • More common in AP and college-level courses
See our Grading Scale guide for how rounding interacts with different percentage-to-letter-grade cutoffs.
What Happens When Settings Change Mid-Semester
One of the most significant — and sometimes alarming — things that can happen is when a teacher changes their grade calc options after grades have already been entered:
IC Recalculates Everything Retroactively
When grade calc options change, Infinite Campus does not grandfather in old grades. It recalculates every student's grade from scratch using the new settings. This can cause sudden, dramatic grade shifts.
- • Switching from total points to weighted categories (or vice versa) recalculates all grades
- • Enabling drop-lowest-score retroactively drops scores that were previously included
- • Changing category weights rebalances all existing category contributions
- • Students may see their grade jump up or down without any new assignments being entered
If your grade changed suddenly without a new assignment being posted, it's likely your teacher adjusted a grade calc option. Use our Grade Simulator to model how different settings would affect your grade.
What Students Actually See
Students and parents don't see the grade calc options panel directly. Here's what's visible on the student portal vs. what's hidden:
What You CAN See
- ? Your overall percentage and letter grade
- ? Individual assignment scores and points
- ? Category names and category averages
- ? Missing/excluded flags on assignments
- ? Assignment due dates and descriptions
What You CAN'T See
- ? Category weight percentages
- ? Whether total points or weighted is selected
- ? Rounding settings
- ? Drop-lowest-score configuration
- ? Extra credit handling method
This invisibility is exactly why tools like our Infinite Campus Grade Calculator are so useful — they let students reverse-engineer their teacher's grade calc options and understand how their grade is computed.
"The grade calc options panel is the control room. Students only see the dashboard — but understanding what's behind it changes everything."

Frequently Asked Questions
What are grade calc options in Infinite Campus?
Grade calc options are teacher-facing settings that control how student grades are calculated. They include the calculation method (weighted, total points, or hybrid), rounding rules, extra credit handling, missing assignment policies, and drop-lowest-score settings.
Can students see their teacher's grade calc options?
Not directly. Students see their calculated grade and assignments on the portal, but the underlying settings panel is teacher-only. Students can infer the method by observing whether categories have visible weights or by asking their teacher directly.
What happens if a teacher changes settings mid-semester?
IC recalculates all grades retroactively. Switching from total points to weighted categories (or adjusting category weights) can shift every student's grade up or down, sometimes significantly.
What's the difference between weighted and total points?
Weighted categories assign fixed percentage weights (e.g., Tests 40%, Homework 20%). Total points treats every point equally — a 100-point test naturally weighs 10× more than a 10-point homework. See our comparison guide for a deep dive.
Does drop-lowest-score apply to all categories?
No. Teachers configure drop-lowest per category. A teacher might drop the lowest quiz but keep all test scores. Ask your teacher which categories have this enabled — it can affect your grade planning strategy.
