Dropping the Lowest Score
Posted by , Last modified by Katherine Martell on 10 February 2016 02:34 PM

One of Moodle's more clever Gradebook features is the ability to remove an item from being calculated into a category total or course score. The Drop the lowest feature can only be found in the Full View area and is primarily used in categories. For example, Professor Smith assigns 11 homework assignments and has created a category in the Full View that contains all of them. At the end of the term, she wishes to remove their lowest Assignment score. That way, Moodle will calculate the student's 10 best scores for the Assignments portion of the class.

Note: It is important to note that gradable items without a score are not counted against your students. If a student has yet to pass in an assignment, it is recommended that you give him/her a zero in either the Assignment itself or manually in the Grader Report. Otherwise, Moodle will not count that grade against him/her when it makes its calculation.


  1. Login to myPlymouth
  2. Select the myCourses tab and click on your class title from the appropriate semester category. You will now be looking at your course's home page.
  3. In the Settings block (usually found on the left sidebar), select Grades.
  4. In the drop down menu entitled Grader report at the top of the page, select the Full View option from the list of choices.
  5. Scroll to the bottom of the Full View to locate the horizontal slide bar. Move the slide bar to the far right of the screen until you've located the Drop the lowest column.
    • You'll only be able to drop the lowest score if it's located in a category (for example: Quizzes or Homeworks). For more information on how to set up categories, please refer to the following link Creating your Gradebook - Building Categories.
  6. In your categories' Drop the lowest text box, type in the number of assignments you wish to remove from being scored.
  7. Scroll to the bottom of the page and select the Save changes button.
  8. When Moodle calculates the score for that category, it will remove each student's lowest score from it's calculation.
