What will be an ideal response?
Good norms should be relevant, representative and up to date (recent). Relevancy is the degree of agreement between the test norm group and the attributes of the test takers. Relevancy of norm groups needs to be decided by teachers and other educational professionals before adopting a test with a given group of students. Representativeness of norms reflects the notion of a random sample in the test authors selecting the norm group for the test. This is extremely difficult and expensive, however, so we must usually settle for something less. At a minimum, we should demand that all significant subgroups of the population be adequately represented. Norm recency means that the norms are up to date and not updated. Test norms ten or more years old are probably outdated. Anytime a test is put out in a new edition the test should probably also contain up to date test norms.
