Convert Scores to Class Grades

This document explains the purpose of class grades and how they are converted, and provides step-by-step instructions for grade conversion (scroll down to view).

The “class grade” column can be used to communicate a student's final grade for the class.
The class grade will also automatically transfer to the online Faculty Grade Report during the grade submission process.

You can either assign class grades by entering or importing values, or define how students’ total scores should be converted to class grades by creating a conversion table. The conversion table can be created manually or by using the conversion calculator.

About the Conversion Table

The conversion table allows you to specify a range for each class grade; percentage scores within this range all receive the equivalent class grade. You create the ranges by specifying a minimum percentage score for each class grade. In other words, you enter just the low end of the range. Scores equal to or greater than the minimum percentage score will receive the equivalent class grade. For example, if 97% = 4.0 is entered in the conversion table, then scores of 97% and 98% will both receive a 4.0. Class grades can be values on the grade point scale for undergraduate or graduate students, credit/no credit, or other grading systems used by your school or department.

How Does the Conversion Calculator Work?

The conversion calculator lets you define two or more points on your grading scale, and then completes the rest of the scale for you. Linear interpolation, a mathematical method for determining values on a straight line between two known points, is used to fill in the grading scale between the points you enter. Remember, the two points you define represent the low end of the range for their respective class grades.

To create a simple linear scale, enter the minimum score for the highest grade, and the minimum score for the lowest grade receiving credit into the calculator. Here are example values for an undergraduate grade point scale:

You can also refine the scale by adding rows and entering points in between these values.

Convert Scores Using the Conversion Calculator

To convert scores to class grades using the conversion calculator follow these steps:

  1. StepsActions

  7. Click Conversion Calculator. The calculator will appear. If you selected a grading system, the highest and lowest credit grades will be filled in automatically.
  8. Enter minimum percentage scores in the spaces at the left, and the equivalent class grade in the space at the right.

    Note: Once you select a grading system, values you enter in the calculator must be one of the grades already listed in the conversion table.

  9. If you want to add additional points, click +Add a row, and then enter values.
  10. Click Apply. The grade conversion table will be populated.
  11. Click Save.
