Three different procedures were used for deriving attribute indices for job factors, these attribute indices being derived for 14 different aptitudes, motor abilities, and physical capacities. These attribute indices, in turn, were used experimentally in two phases of the study. In one phase they were correlated with worker trait requirements of 401 jobs as published by the U. S. Employment Service. These published job requirements were given for the same attributes. The correlations were all significant, and of essentially the same magnitude, as those obtained in the previous study in which the 162 items were treated individually. In the second phase, the indices of four attributes were derived for 43 Naval ratings jobs. These, in turn, were correlated with test validity coefficients from 125 test validation studies with these 43 Naval ratings. This analysis resulted in significant relationships for most of the tests and subtests. The results of this analysis were generally more positive than a corresponding type of analysis in the previous study of 140 varied industrial jobs for which published validity data were available. In general, the results of this study lend encouragement to the possibility of being able to establish job requirements through what are essentially job analysis procedures. Author
