What defines a norm group in norm-referenced criteria?

• A. It is composed of a large population of representative applicants, such as those with varying educational, cultural, occupational backgrounds, and years of experience.
• B. It consists of top performers only.
• C. It is chosen by the test administrator from a single institution.
• D. It is based on a random sample of current employees.

Answer: (A)

Norm-referenced scoring uses a norm group to define what is typical for the test’s intended population. This means building the norms from a large, representative sample of the people the test is meant to serve, so the resulting distribution accurately reflects real-world variability in education, culture, occupation, and experience. That representative mix allows scores to be interpreted as relative standing (percentiles or standard scores) within that population, not against a fixed standard. Choosing a group that only includes top performers would distort what’s typical, making percentile ranks meaningless for most applicants. Selecting participants from a single institution introduces bias and doesn’t represent the broader applicant pool. A random sample of current employees may skew norms toward internal hires and fail to capture the diversity of external applicants the test is designed to assess.
