Sometime around the end of the nineteenth century, American colleges and universities began to use a form of grading students that resembles what most high schools, colleges, and universities still use today: A, B, C, D, and F. The grades are intended to be a way of measuring and reporting a student’s performance on a given assignment or within a given subject over a period of time. They are useful for that task, but far from perfect. At Trinitas we also grade students using a variation of the aforementioned marks.
