The Grading System | History Of

While various schools experimented with 100-point scales and percentages, the letter system we recognize today was pioneered by in 1897. Their original scale looked a little different than ours: A : 95–100% (Excellent) B : 85–94% (Good) C : 76–84% (Fair) D : 75% (Passed) E : Below 75% (Failed) Who was Horace Mann? - by Robert Talbert

Before the 1800s, student evaluation was intimate and subjective. In early American universities, professors didn't hand out report cards. Instead, students faced a single, high-stakes oral exam at the end of their studies. A panel of experts would listen and simply decide if the student was ready to graduate or not. History of the Grading system

By applying this factory logic to the classroom, Farish could process hundreds of students quickly and standardize the "output" of his teaching. This approach made education more efficient for the rising industrial workforce but shifted the focus from deep learning to rote memorization to pass the "quality check". While various schools experimented with 100-point scales and

For most of us, getting an “A” or a “B” feels as fundamental to school as desks and chalkboards. But the modern grading system isn't an ancient tradition; it’s a relatively recent invention born from the Industrial Revolution and a 19th-century desire for efficiency. In early American universities, professors didn't hand out

So, how did we get from "pass/fail" oral exams to the letter grades we see today?

The shift toward formalizing performance began at Yale in 1785. President Ezra Stiles recorded the first documented grading scale in his diary, sorting 58 students into four Latin categories: Optimi (the best), Second Optimi , Inferiores , and Pejores (the worst). This was the first major step toward ranking students against one another rather than just assessing their mastery of a subject.

In 1792, William Farish , a tutor at the University of Cambridge, introduced a radical idea: assigning numerical "marks" to student work. Farish was inspired by the manufacturing industry, where factories "graded" products—like shoes—to determine their quality and price.
