Use grading scales that ensure accurate measurements

To ensure that grades accurately communicate student achievement, instructors must consider the effects of calculating central tendency or an average and the effect of extreme marks, especially zeros (O’Connor, 2010). Instead of using the 100-point scale, minimum grading and a four-point scale can help to make grades more accurate representations of student achievement.
