The way you calculate grades is an expression of your values and goals related to the course material. It communicates to your students what is most important and how they should spend their effort.
Below are three basic models that teachers typically use to calculate grades. Also see To Curve or Not to Curve for a discussion about the advantages and disadvantages of curving.
Model 1: Weighted Letter Grades
Example: |
Characteristics: |
|
Assignments:40% |
|
Model 2: Accumulated Points
Example: |
Characteristics: |
|
92-100 points = A |
|
Model 3: Definitional System
Example:To earn a particular course grade, a student must meet or exceed the standards for each category of work. If not all of the category expectations are met on the highest level, the student receives the grade for which all the category expectations are met.
If a student receives an A average in their graded work but only passes 80% of their labs, they would receive a course grade of B because that was the highest level at which they meet the standards for both categories.

Other Options
Penalties and Extra Credit
- Penalties call the student’s attention to the seriousness of infractions and are best used in matters for which the teacher feels strongly or which carry a heavy penalty in the outside world.
- Extra credit is useful when teachers want to let students compensate for failures in other areas.
- Both of these options can be used with any model.
