The occupational scale . . . show(s) a high correlation between occupational ratings and [Evaluative Participation]. However, after the work on these data was completed, further modifications were made. Experience with this revised form of the occupational scale suggests that it is an improvement over the original form and that it should be used in future applications of the ["Index of Status Characteristics"] method.
The modified classification resulted when it was decided to treat occupation as a two-dimensional factor and to use the various occupational groups which had been defined by Edwards, [and] to accept the fact that there were gradations within each of these groups with respect to degree of skill required for the job and the amount of prestige attached to the job. Because this form of classification was more fluid, the job of classification became easier and at the same time more accurate. Thus, any category of occupation was not limited to a single rating but could potentially be given a rating of from one to seven, depending upon the degree of skill required for a particular job rather than that associated with a general occupational group.____________________
