Norms are the benchmarks used to determine how a person scores relative to others taking the same test. Without norms, it would be impossible to compare someone's score to that of others in a meaningful way. Scales, levels, and scores are all components of a psychological test, but none on their own would allow for a person's score to be compared to others.
