Grading refers to the process of evaluating and assigning a level or grade to something, such as an assignment, test, or performance. It can also refer to the act of determining the quality or value of something based on specific criteria. In education, grading is commonly used to assess students' work in order to provide feedback on their progress and understanding of the material being taught. Grades are typically given on a scale, such as A+ to F, with varying levels of achievement within each grade level.
