The primary purpose of this study was to obtain estimates of the human attribute requirements of the job elements of the Position Analysis Questionnaire (PAQ). A secondary purpose was to explore the reliability of job-related ratings as a function of the number of raters. A taxonomy of 76 human attributes was used and ratings of the relevance of these attributes to each of the PAQ job elements were obtained. Conclusions drawn from these analyses were: (1) Raters are able to rate the relevance of human attributes to job elements in a structured job analysis instrument such as the PAQ with respectable reliability, and (2) A large number of human attributes appear to be relevant to the job elements of the PAQ. Implications drawn from these conclusions were: (1) The attribute profiles of the PAQ job elements seem to be of potential use in determining job attribute requirements through job analysis with the PAQ, and (2) Such profiles, in turn, may be useful in establishing the synthetic validity of personnel tests. The determination of the reliability of the ratings as a function of the number of raters resulted in the conclusion that 8 to 10 raters usually would provide reasonably reliable ratings. (Author/MF)
