Mark W. Durm stated that "it was not until 1792 that Cambridge University implemented the GPA and started the legitimate grading system" (2). In the 18th century, teachers were paid based on the size of their classrooms. Over time, the assessment policy has adapted to reduce teachers' workloads, allowing them to have larger classes. Because of this structure, student success has become less important than the grading system. The system used before the AAP was more beneficial than the new system implemented. For example, multiple students interacted with each other, resulting in students learning important communication skills. The level of friendly competition and student understanding in class was enough for the teacher to know that the students understood the material (gpa-calculator.us). The GPA grading system changed learning because it made it easier for teachers to assign points and a grade, rather than make sure students understood concepts. This is why students today are solely obsessed with getting an “A,” rather than appreciating how to gain knowledge for the sake of individual growth and understanding. By the 20th century, most schools in the United States had conformed to the GPA grading system and introduced an entirely new structure of grades.
