ABSTRACT
When Cronbach (1957) called for the unification of experimental and correlational universes of discourse in psychology, it was not a consummation that, even if devout and desirable, could occur immediately for tests and measurements. And even now, if a degree of confluence has been achieved in the concepts and operational definitions of item-generation theory, applications to test construction are widespread neither in the domains of test content, nor in the use that is made of theory by large-scale test constructors. But if used, item-generation theory at one and the same time brings about a remarkably robust test-construction medium. To enable a perspective on the state of the art, historical and theoretical influences on the derivation of tests for initial screening of job applicants are outlined and then reviewed.
