This study was carried out to explore the extent to which current pay rates of jobs can be predicted on the basis of worker-oriented job variables. For this purpose the Worker Activity Profile Gordon and McCormick, 1963 was used. It consists of 162 job activities of a check-list or rating scale nature that can be used in analyzing any job. The check-list items have numerical values of 0 and 1, and the rating-scale items values of 1 to 7. A sample of 253 jobs was used in this study these jobs were selected because national wage or salary data had been published for them by the Bureau of Labor Statistics. The national weighted average rates of pay for these jobs were used as a criterion. The total sample was divided into an experimental sample 154 jobs and a hold-out sample for cross-validation 99 jobs. Analyses with the experimental group were carried out to identify the items of the Worker Activity Profile which were related to rates of pay. Three combinations and weightings of such items were then used with the hold-out sample. While the three cross-validation procedures resulted in significant correlations, they were of only moderate size. For example, seven items, with statistical weights, gave a correlation with pay rates of .36. Various factors which might serve to attenuate the magnitude of the relationship were discusses. Author
