Brief History of Grading Systems

Grading systems have evolved significantly over time. In 1785, students at Yale were ranked based on "optimi" being the highest rank, followed by second optimi, inferiore (lower), and pejores (worse). At William and Mary, students were ranked as either No. 1, or No. 2, where No. 1 represented students that were first in their class.

In 1887, Mount Holyoke College became the first college to use letter grades similar to those commonly used today. The college used a grading scale with the letters A, B, C, D, and E, where E represented a failing grade. This grading system was far stricter than those commonly used today, with a failing grade being defined as anything below 75%.

Today, while letter grades provide an easy means to generalize a student's performance, there continues to be debate about their effectiveness and alternatives that might better promote learning and improvement.
