Robustness of Job Classification Systems: An Examination of Alternative Indicators.
Hartman, E. Alan; And Others
Any attempt to describe every job position and the activities contained in it would yield a confusing mass of information. Consequently, industrial psychologists have generated methods for classifying occupational positions into a smaller number of jobs or job families. Based on prior research it has been concluded that different kinds of job descriptors yield different job classifications. The limited robustness of such classification systems observed in previous efforts might be attributed to the use of only a few, relatively homogeneous jobs. To examine this hypothesis, both task and ability requirements data were used to describe some 600 positions in occupational fields ranging from clerk to computer programmer. All student assistant positions within a midwest university were studied. A job analysis questionnaire was developed and 79 supervisors of student assistants were asked to complete one response sheet for each unique student position supervised. Separate occupational classifications were developed for each type of indicator using a Ward and Hook (1963) procedure. In cross-validation, it was found that the two indicator types yielded very similar occupational classifications. These findings support the validity of job families derived from the Ward and Hook clustering procedure for both tasks and skills/abilities. (Author/NB)
