Which score indicates the percentage of pupils in the norm group scoring below a given pupil's raw score?

• A. Percentile Rank
• B. Grade Equivalent
• C. Z-score
• D. Standard Score

Answer: (A)

The main idea here is about relative standing within a norm group. The score that represents the percentage of peers who scored below a given pupil’s raw score is the percentile rank. It directly expresses how a student compares to others by showing what portion of the norm group scored lower. For example, at the 75th percentile, 75% of peers scored below that student.

Grade Equivalent relates to grade level interpretation of a raw score, which can be misleading for comparing performance. A Z-score shows how far a score is from the mean in standard deviation units, not the exact percentage of peers below. A standard score places scores on a standardized scale but doesn’t directly express the percentile of peers below the score.
