Abstract	In order to develop a valid replacement for the difficult to administer and costly Chalk Carving Test presently used in screening Dental Laboratory Specialist (DLS) candidates, an experimental battery of perceptual tests was given to 172 prospective DLS students. Dexterity tests were also given to a subsample. Experimental laboratory ratings and final course grades were obtained for the subjects. Tests were factor analyzed, and individual and multiple validity correlations were computed. The Chalk Carving Test presently used in screening prospective DLS students did not demonstrate significant validity with laboratory ratings or final grades. This lack of relationship seems partly due to somewhat subjective scoring, as reflected by a low interrater reliability. While the Peg Turning test appeared to make an independent contribution to prediction of laboratory ratings, this apparatus test presents cost and test administration problems which make it less attractive. In contrast, the use of the Perceptual Composite (in place of the Chalk Carving Test) would reduce test administration time about 15%, test scoring time at least 50%, and test material costs would also be reduced. In addition, this study indicates that DLS training attrition should be lowered through utilization of the Perceptual Composite. (Author/MV)
