Which statement best differentiates norm-referenced interpretation from criterion-referenced interpretation?

• A. Norm-referenced interpretation compares scores to a fixed standard
• B. Criterion-referenced interpretation uses percentile ranks for interpretation
• C. Both rely on normative samples
• D. Criterion-referenced interpretation uses a fixed mastery standard to interpret performance

Answer: (D)

The main distinction is what the score is interpreted against. In norm-referenced interpretation, the emphasis is on how a person compares to a larger group, using the distribution of that group’s scores (like percentile ranks or standard scores). It’s about relative standing rather than whether a specific skill or objective has been met.

In criterion-referenced interpretation, the focus shifts to whether the person has achieved predefined criteria or a fixed level of mastery. The standard is set in advance, and interpretation centers on reaching or failing to reach those benchmarks, regardless of how others perform.

Therefore, a statement that criterion-referenced interpretation uses a fixed mastery standard to interpret performance best captures the difference: mastery is determined by meeting a predefined criterion, not by relative position within a normative sample.

For contrast: using a fixed standard is characteristic of criterion-referenced approaches, not norm-referenced ones. Using percentile ranks or normative comparisons is the hallmark of norm-referenced interpretation. And criterion-referenced interpretation does not require normative samples to make sense.
