Normative data can be used in several ways. Norms are a valuable source of information to determine the impact of diseases (Stewart et al., 1989) or the effectiveness of a treatment (O'Brien, Buxton, & Ferguson, 1995).

Why are test norms important?

Norms enable one to make meaningful interpretations of obtained test scores, such as making predictions based on evidence. Developing appropriate norms depends on size and representativeness of the sample.

Why is it important to evaluate test scores against normative data?

The purpose of test norms is to identify what “normal” performance might look like on a specific assessment. As a society, we have a tendency to characterize all measurable traits normatively, which is why normative scores can be so useful for describing academic performance.

What are the advantages of normative approach?

What are the advantages and disadvantages of norm-referenced testing?

The primary advantage of norm-reference tests is that they can provide information on how an individual's performance on the test compares to others in the reference group. A serious limitation of norm-reference tests is that the reference group may not represent the current population of interest.

What information does a norms table give to a test taker?

A norm table provides test scores and their corresponding percentiles and t-scores. Percentiles indicate how well (in terms of a percentage) a candidate has done compared to other candidates who previously sat the same test. T-scores indicate how far a candidate's score is from the mean or average score.

What is an example of a norm based assessment?

Examples of norm-referenced tests include the SAT, IQ tests, and tests that are graded on a curve. Anytime a test offers a percentile rank, it is a norm-referenced test. If you score at the 80th percentile, that means that you scored better than 80% of people in your group.

What does norms mean in assessment?
