Weights

Any weighting that you apply to your gradebook will affect the students’ averages. In calculations, averages are multiplied by weight values. The weighted averages are then summed and divided by the sum of the weights. In this way, weights are relative and do not have to total 100. You can set weights for the following scenarios:

  • Individual Assignments — You can determine how much each individual assignment should be weighted in the students’ averages. For example, you can weight a homework assignment at a smaller value than a chapter test, so the test will contribute more to the final average.
  • Categories — You can weight categories of assignments differently. For example, you can set the Test category to a weight of 75, the Homework category to a weight of 15, and the Quiz category to a weight of 10.
  • Specific Terms — You can determine how each term should be weighted in the students’ averages. Usually terms are set to equal weights (for example, Term 1 = 50 and Term 2 = 50).
  • You can also use any combination of the three above scenarios, or you can choose not to use weighting at all. Weights are applied first to assignments within term-categories, then to categories within terms, and finally to terms within the overall average.

See examples of weight calculations!

How to Set Weights for Specific Terms

You can set weights for each term or special assignments.

  1. On the Settings page, click Weighting from the list of Grading options to access the Weighting settings.
  2. Check Enable Term Weights.
  3. Double-click in each Weight box and enter the weight value for each term and special assignment.

    Weights are relative and can be any value. The sum of term weights does not have to equal 100%.

  4. Click Save.
    If a new term is created in the gradebook, verify the new term’s weight value in the Weight Term area.

How to Remove Weights from Terms

To remove weights from terms, clear Enable Term Weights and click Save. The weights will be removed from ALL terms and special assignments, readjusting the students’ averages.

How to Set Weights for Categories of Assignments

You can set weights for each category that you have already created in your gradebook.

  1. On the Settings page, click Weighting from the list of Grading options to access the Weighting settings.
  2. Check Enable Category Weights.
  3. Double-click in each Weight box and enter the numeric weight value for each Category.

    Weights are relative and can be any value. The sum of category weights do not have to equal 100%.

  4. Click Save.
    Any time you add a new assignment to your gradebook, choose a category for the assignment or the assignment will default to the double-asterisk (**), exempt category.
    If a new category is created for an assignment in the gradebook, its weight will default to a value of zero (0). You will need to set the new category’s weight value in the Weight Categories area.

How to Remove Weights from Categories

To remove weights from categories, clear Enable Category Weights and click Save. The category weights will be removed from ALL assignments, readjusting the averages.

How to Set Weights for Individual Assignments

When using assignment weights, the percent score the student received (score/points possible) is multiplied by the weight, so the higher the weight value, the more that assignment contributes to the overall average.

  1. On the Settings page, click Weighting from the list of Grading options to access the Weighting settings.
  2. Check Enable Assignment Weights to allow weights to be set for individual assignments in the gradebook.
  3. Click Save.
    Anytime you add a new assignment to your gradebook, you will have to set the weight value to determine how much that assignment will affect the students’ averages.

How to Remove Weights from Assignments

To remove weights from assignments, clear Enable Assignment Weights and click Save. The weights will be removed from ALL assignments, readjusting the averages.
