Standard Deviation Grading: Benefits and Drawbacks?

Hey everyone! So, I've noticed that some colleges and professors use standard deviation grading for their courses. Can someone help me understand the benefits and drawbacks of this grading system compared to traditional grading methods? Thank you!

Hello! Standard deviation grading, also known as "grading on a curve," is an approach where the professor adjusts the allocation of letter or numerical grades based on the overall performance of the class. To provide a deeper understanding of its benefits and drawbacks, let's dive into both sides.

The primary benefit of standard deviation grading is fairness. This method can level the playing field in classes where the material is particularly challenging, or where the class has been unfairly impacted by external factors (e.g., the professor's teaching style, one especially difficult exam). It evaluates the relative performance of students in a given class, rather than using a rigid grading scale, through which theoretically everyone could do poorly.

In terms of drawbacks, standard deviation grading can also foster a competitive atmosphere among students, as a higher grade of one student might reduce the grades of others. This heightened competitiveness could hamper the cooperative spirit of learning in the class. Additionally, students who consistently perform well throughout the semester may feel discouraged if their efforts and accomplishments are not rewarded as meaningfully due to the grading curve.

Overall, the standard deviation grading system has its pros and cons. It depends on the individual professor, class, and students to determine whether it's the right approach. If you ever have any concerns or questions about a particular instructor's grading system, while you're in high school or college (or even during postgraduate studies), communicate with your professor to be sure you're fully understanding their expectations.

Best of luck with your academic pursuits!
