Check that your gradebook setup is consistent with the grading scheme for your course.

• By default, the gradebook is set to Mean of grades and will simply average any grade items together. In nearly all cases, additional set up is required. For example, you may need to update the aggregation method and add weighted categories to organize your gradebook items into groups.
• If your syllabus lists categories by percentage (e.g., Discussion Boards 30%, Projects 30%, Quizzes 30%, Participation 10%), use the Weighted mean of grades method. If your course is points-based, you can use Natural (Sum of Grades), but if this is the case, be sure that the point values you assign to each activity accurately reflect their intended weight in the overall course grade. In other words, higher-stakes items should be worth more points than lower-stakes items so the totals correctly represent your grading scheme.

Confirm accuracy by manually calculating the total for one or two students using your syllabus. This quick check ensures Moodle matches your grading scheme. If totals dont match, adjust your aggregation method or category weights and re-check.

Hidden grades can cause discrepancies between the totals you see and what students see. By default, if an assignment or quiz is hidden, Moodle also hides students grades for that item.

Reveal any hidden grades or delete unused hidden assignments to keep course totals visible and accurate. To check or adjust visibility settings:

1. Open the graded item’s menu (⋮)
2. Select Availability
3. Confirm the visibility setting  

By default, the Moodle gradebook ignores empty or blank cells when calculating course totals. If students have not completed an assignment and you want a zero to be factored into their course total, you must manually enter a zero for that assignment.

Zeros can be entered directly in the Grader Report, which can be accessed from your course under the Grades tab. To enter grades directly in the gradebook:

1. Turn editing on. If editing is not enabled, the cells for entering grades will not be visible.
2. Click into a cell to enter the grade. The cell will be outlined in green when active. Type the numerical grade.
3. Save your changes. After entering or updating grades, click Save changes to record the new grades in the gradebook.

To update all empty grades for a single grade column at once you can go to the Single view screen for that item.  To access single view, click on the cell actions menu at the top of the column (⋮) and select Single view for this item.

Once you have accessed the single view screen for that item, click on the Actions menu and select Bulk insert grades.

A popup window will open warning you about overriding non-zero grades. You cannot get them back.

1. Check the box to confirm your understanding
2. Select Empty Grades
3. Set Insert new grade to zero (or whatever grade is appropriate for that item)
4. Once you hit Save, the new grade will be entered for all empty grades on that assignment

Orange cells in the gradebook indicate that a grade has been entered directly in the gradebook (overridden) instead of being pulled from the activity's grading interface. Overriding a grade is fine for individual items but if you override a category total, Moodle will stop recalculating it automatically when new grades are added.

Quizzes have their own visibility settings that can prevent grades from showing, even if everything else looks correct in the gradebook. If your students can't see their quiz grades, and you've checked all other settings above, you can troubleshoot with this quick check.

Locate the quiz and click on it to open. Then go to the Settings tab

Scroll down and expand the Review Options section to check and adjust what students can see During, Immediately After, Later and After the quiz is closed.

Look out for these common reasons why students might not be able to see their quiz scores.

1. If the Points (students' score) box is unchecked in any of the columns, students won’t see their score during that time period. Here are some common Scenarios:
   • If Points is not checked in the Immediately after the attempt column, students won’t see their score right after finishing.
   • If the Points box is checked in the Later, while the quiz is open column, they can view their score later on, until the close date (if set).
2. If you’ve set a close time for the quiz, the last column applies after that time. If there’s no close time, that column is disabled. You can confirm whether or not you have enabled and set Close the quiz under the Timing tab (in your quiz settings)
