Differences in job analysis information resulting from differences in the specificity of job information units chosen for analysis were also examined. Students having no prior direct experience with one of three jobs -- secretary, firefighter, or power plant operator -- rated the importance of abilities, both job specific and general, tor successful performance of this job. These three jobs varied in terms of general familiarity associated with them, as determined in a pilot study. ln addition, this study compared the accuracy of secretary ability importance ratings for three groups of students differing in their familiarity with the job of secretary. Test scores on the General Aptitude Test Battery were weighted by both student and expert ability importance weights to determine whether rating differences between the two job analysis sources would influence selection decisions. Accuracy did vary as a function of job familiarity, with secretary ratings being more accurate than firefighter or power plant operator ratings. Importance ratings for specific abilities were more accurate than those for general abilities. The patterns of predicted performance in weighted GATB scores using student and expert weights were quite similar, although there were mean differences between the two weighting strategies. It is suggested that criterion-referenced selection decisions may vary depending on an analyst’s job familiarity, whereas decisions based on norm-referenced measurement would probably not.viii, l09 leavesapplication/pdfenIn CopyrightLD5655.V855 1983.D655Job analysisThesis
