What grading system compares individual scores against a predetermined average score?

The relative grading scales system evaluates student performance by comparing individual scores to a predetermined average or mean score of a group. This approach determines the relative standing of each student based on their performance in relation to peers rather than an absolute standard.

In this system, students might be graded on a curve, which means that their scores are adjusted according to the performance of their classmates. This method can help in situations where the test or assignment was particularly challenging or where the scores generally cluster in a specific range.

Relative grading scales are useful for fostering a competitive learning environment, as students are motivated to perform better to surpass their peers. In contrast, other grading systems, like absolute grading standards, assess students against fixed criteria or performance benchmarks, rather than evaluating their scores relative to others.
