The theory of score validity has undergone several revisions within the measurement community. The current consensus among professionals is a rejection of the trinitarian doctrine (J. P. Guion, 1980) of score validity and the recognition of a unified view that includes social consequences of test interpretation and use. While some aspects of the "unified theory" (S. Messick, 1989) are controversial, the integration of this view is already changing professional standards. This paper reviews the history of score validity and the ongoing research concerning alternate approaches to validity theory. The paper also challenges the attempt to add "consequential validity" as a new validity construct. The concept of social consequences as a validity question leads to a multitude of problems of measurement that researchers may hesitate to address. (Contains 12 references.) (Author/SLD)
