Grade (education) - Wikipedia

A grade in education can mean either a teacher's evaluation of a student's work or a student's level of educational progress, usually one grade per year. This article is about evaluation of students' work. For more information about levels of education, see School grades (US) or School years (United Kingdom).

In the United States and some other countries, a grading system of A, B, C, D, and F is used. Sometimes the system is expanded to add plus or minus to each letter. It should be noted that practice can vary from this general picture.

	Percent	Letter	Points
Excellent	90-100	A	4
Good	80-89	B	3
Average	70-79	C	2
Barely Passing	60-69	D	1
Fail	0-59	F	0

Teachers usually grade assignments on a percentage scale. For example, on an exam having ten questions, if a student answers eight questions correctly, the teacher will give a grade of B or 80%. At the end of the class term, the average of the percentages is calculated to determine a final grade for the class. Then the letter grades from each class are converted to points, and a grade point average or GPA is computed.
