63. Valuation on an individual basis shall be effected according to the job-to-job method of comparison, that is, by comparing a predominantly female job class with a predominantly male job class of equal value.
In applying the job-to-job method of comparison, where there are two or more predominantly male job classes of equal value but with different remuneration, comparisons are made on the basis of the average remuneration for those job classes.
Where the job-to-job method of comparison cannot be applied to a predominantly female job class, its remuneration shall be valuated proportionately to the remuneration of the predominantly male job class the value of which is closest to its value.
