Used in schools, industries, military forces and governments to look at individual differences that might affect performance. Argument that the tests discriminated through the inclusion of unfair items. Refers to the consistency with which individuals respond to test stimuli. Test-retest reliability: the extent to which an individual makes similar responses to the same test stimuli on repeated occasions. Equivalent-forms reliability: parallel forms of a test are developed to avoid the preceding problems. Split-test reliability: test is divided into halves and participants" scores on the two halves are compared (one possible index of internal consistency)
