A norm-referenced test (NRT) is a type of test, assessment, or evaluation which yields an estimate of the position of the tested individual in a predefined population, with respect to the trait being measured. This estimate is derived from the analysis of test scores and possibly other relevant data from a sample drawn from the population. That is, this type of test identifies whether the test taker performed better or worse than other test takers, but not whether the test taker knows either more or less material than is necessary for a given purpose.
The term normative assessment refers to the process of comparing one test-taker to his or her peers.
Norm-referenced assessment can be contrasted with criterion-referenced assessment and ipsative assessment. In a criterion-referenced assessment, the score shows whether or not the test takers performed well or poorly on a given task, but not how that compares to other test takers; in an ipsative system, the test taker is compared to his previous performance.
