Proportional Value: Regression Analysis

​​Proportiona​​l Value Comparison Method

Proportional value indirectly compares female and male job classes by looking at the relationship between the value of the work performed and the compensation received by male job classes and applying the same principles and practices to compensating female job classes. The Act specifies that pay equity is achieved by proportional value when the relationship between the value of the work performed and the compensation received is the same for both female and male job classes [21.3(1)].

The proportional value method is applied in establishments where male job classes are not available in large enough numbers, or else their job values are such that they cannot be used for direct comparisons. For example, in two-tiered pay systems, the male management job classes may be valued much higher than the female job classes, and thus, they may not be appropriate comparators.

To achieve pay equity using the proportional value method, employers must:

  • select a representative group of male job classes;
  • establish the relationship between job values and job rates;
  • calculate pay equity adjustments; and,
  • increase wages for underpaid female job classes.

For further information, refer to the Guide to Interpreting the Pay Equity Act.
