A "Grade (Rank)" refers to a classification system used to evaluate and categorize individuals, objects, or performances based on specific criteria. This system is commonly applied in various fields, such as education, where students receive grades to reflect their academic performance, or in the military, where personnel are assigned ranks to indicate their level of authority and responsibility. Grades or ranks can also be used in other contexts, such as sports, where athletes are ranked based on their performance in competitions, or in job positions, where employees may be graded according to their skills and experience. This hierarchical structure helps to establish standards and expectations within a given system.
