Option C β grading system A grading system converts raw scores into a limited set of categories, such as A, B, C or grades like O, A, B, C, to summarize levels of achievement. Each grade corresponds to a range of marks, making evaluation more communicative and less focused on minor numerical differences. Such systems are intended to highlight broad performance bands rather than precise scores. Therefore, reporting results as letter categories rather than exact marks is known as using a grading system.
Option A:
Option A, narrative report, usually consists of descriptive comments on a learnerβs performance and behaviour without necessarily using formal grades or marks. While narrative feedback can be valuable, it is not what the stem describes, which specifically mentions letter categories like A, B and C.
Option B:
Option B, marks statement, reports the exact numerical scores a learner has obtained in tests or examinations. It does not group these marks into categories; instead, it maintains full numerical precision. Since the question refers to replacing exact marks with letter ranges, marks statement is not correct.
Option C:
Option C, grading system, is explicitly designed to translate raw scores into meaningful categories for easier interpretation and communication. Grades like A, B and C indicate different levels of mastery and align precisely with the practice described in the stem. Thus, this option correctly completes the statement.
Option D:
Option D, percentile rank, indicates the percentage of students in a reference group who scored below a particular score. It is a statistical measure used mainly in norm-referenced contexts and does not itself represent ranges as letter grades. Consequently, percentile rank is not the appropriate term for what the question describes.
