Using a 12 point or 4 point (or similar type) grading system

You may use scales other than the standard ones in the dialog box. For example, you may prefer to use a 12 point scale or a 1 to 4 scale. This is easily done in one of two ways, depending on how you want to enter scores and how you want your averages to appear.

  • If you want to show final averages of 1 – 100% but want the final grade to be a 1-4 grade, you can modify the letters (A,B,C) of your grade scale to become numbers (1-4 or any scale). For example, if you change the letter B to a 3 in the grade scale dialog box, then a student with an 85% average will be assigned a 3, rather than a B.
  • Alternatively, if you prefer to calculate grade averages of 4.0, 3.5 etc., you should set the tests’ points possible to 100 and enter the numbers 1 to 4 as scores in your test columns. You could then assign a grade of an A to a 4.0 or you could select Use Numeric Grades, which would result in grades of 4.2 to correspond to the averages. If you enter letters as test scores and want them to result in 1-4 averages, be sure to use the Grading Symbols dialog box to set the percent value to 1-4, rather than 1-100.

Do not click either of the scale buttons after you have modified any values unless you want to replace your modified custom scale with one of the standard scales. Remember that whatever scale appears in the Set Grading Scale dialog list is the one that will be used when you assign grades. If you want to use your grade scale in other gradebooks, you can use the Gradebook to Gradebook Copy.
