A norm-referenced assessment is a standardized test that compares a student‘s performance to that of a larger group, known as the “norm group.” These assessments are designed to rank test takers against each other, rather than measuring their knowledge against a fixed standard.
Key features of norm-referenced assessments include:
- Comparison to peers: Results are interpreted relative to other test-takers.
- Percentile ranks: Scores are often reported as percentiles.
- Bell curve distribution: Results typically follow a normal distribution.
- Competitive nature: They identify high and low performers within a group.
Norm-referenced assessments are commonly used for college admissions (e.g., SAT, ACT), intelligence tests (e.g., IQ tests), and some standardized achievement tests. While they’re useful for comparing students across different schools or regions, they don’t necessarily measure mastery of specific content or skills.
