The Position Analysis Questionnaire (PAQ) is a structured job analysis procedure that provides for the analysis of jobs in terms of each of 187 job elements, these job elements being grouped into six divisions: information input, mental processes, work output, relationships with other persons, job context, and other job characteristics. Two cluster analysis procedures were used in the clustering of jobs on the basis of data from the PAQ. The BC-TRY program was carried out with the 14 overall or general job dimensions as applied to a reasonable varied sample of 3,700 jobs and resulted in the identification of 33 job clusters. The CODAP (Coordinated Occupational Data Analysis Program) was based on the scores on 21 of the divisional job dimensions for a sample of 800 jobs, and resulted in the identification of 45 clusters. The differences in the results may be due to the differences in the nature of the job dimensions used in the two instances, rather than being associated with the clustering procedures as such. The 95-page appendix contains the tables of data (15 pages) and line graphs for the job clusters resulting from the two programs. (Author/AG)
