THE COMPARABILITY OF JOB EVALUATION METHODS IN SUPPLYING APPROXIMATELY SIMILAR CLASSIFICATIONS IN RATING ONE JOB SERIES

There is a belief that any job evaluation method, when correctly applied to a series of jobs, will result in approximately the same rating classification as that supplied by any other method for the same job series. This study was aimed primarily at a determination of the extent to which a number of job evaluation methods, differing in methodology, and presently in use within South Africa, would in fact supply similar classifications. Correlation coefficients among the sixteen participating organisation job evaluation point ratings for a sample of jobs which were heterogeneous in terms of type and level within the job hierarchy, ranged from .93 to .99 with an average of .98. Coefficients for the same sample of jobs divided into a high prestige category and a low prestige category, ranged from .60 to .99 and .86 to .99 respectively. Correlation coefficients among point ratings for the same organisations but for a second sample of jobs, homogeneous in terms of type and level within the job hierarchy, ranged from .75 to .99 with an average of .90. These results indicate a high degree of agreement among job evaluation methods in assigning point ratings, irrespective of job type and level within the hierarchy.
