What is the process of evaluating a student's performance and assigning a letter or number called?

The process of evaluating a student's performance and assigning a letter or number is known as grading. Grading provides a systematic way to measure and communicate the level of a student’s understanding, skills, and competencies in a subject area. This process is integral to the educational system, as it informs both instructors and students about progress and areas needing improvement. Grading can utilize various methods, like tests, projects, or practical applications, ultimately translating student performance into a quantifiable format, such as letters (A, B, C, etc.) or numbers.

The other choices represent related concepts but do not specifically define the act of assigning a performance level. For example, assessment refers broadly to the methods and tools used to gather information about student learning, while outcome evaluation focuses on evaluating the educational results in relation to established objectives or standards. Curriculum design pertains to the planning and structuring of educational content and methods rather than the evaluation of student achievement.
