Standardized Test

Originally a standardized test was simply a standard test Ð of academic achievement or of knowledge in a specific academic or vocational domain. It has since acquired the meaning of a written test whose scores are interpreted by reference to the scores of a norm group which has taken the test and which is usually considered to be representative of the population which takes the test. For example, standardized tests of academic achievement provide conversion tables showing the percentile ranks in the norm group of all possible raw scores. Some standardized tests are now analyzed with item response theory. or skills. This is called summative testing. Formative testing is a test designed to aid learning by diagnosing students' knowledge and skills thereby permitting a suitable learning programme to be created.
