Which score is described as a scale using grade levels (1st grade, 2nd grade, etc.) to measure a student's progress relative to peers?

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

Answer: (A)

Grade-equivalent scores use a scale tied to grade levels—1st grade, 2nd grade, and so on—to show where a student’s performance falls relative to peers at those grade levels. This format is meant to express progress in terms of the grade level you’d expect for typical students at that point in the school year, making it possible to compare a student’s development to grade-level expectations. Percentile rank describes a student’s standing in a distribution relative to peers, not a grade-level scale. A z-score standardizes a score by counting how many standard deviations it is from the mean, and a standard score (like a T-score or IQ-like metric) is a fixed-scale statistic with its own mean and spread, again not tied to grade levels.
