This paper presents an overview of recent literature concerning the declining interest and application of psychological testing within clinical services. It reflects a dissatisfaction with personality assessment techniques primarily due to a distorted presentation by the graduate schools training applied and professional psychologists. New and innovative ways of evaluating previous validity and reliability studies of psychological test data is also presented. Evidence from direct clinical experience indicates a strong dependency upon adequate diagnostic evaluations, and continued training in this area is strongly encouraged by practitioners within institutional and community agencies. The professional school model is looked to for a resurgence and perhaps redefinition of the psychodiagnostician's role and function. (Author)
