Steps to Proportional Value (PV)

​​​​Proportional value builds on the work already done with the Job-to-Job approach.​

To achieve Proportional Value, employers must:

  • determine unmatched female job classes;
  • select a representative group of male job classes;
  • calculate a Proportional Value job rate line;
  • calculate adjustments; and,
  • prepare and post a pay equity plan, then implement the rate adjustments.

Developing a Job Rate Line

This section shows you three ways to apply the Proportional Value method. They are:

  • a free-hand method
    • where you mark the job value and job rate of each job class free-hand on a graph to more or less form a straight line
  • a computer regression analysis program
    • where you use a computer's regression program to calculate the job rate line and produce Proportional Value job rates
  • a manual regression analysis calculation
    • where you calculate Proportional Value job rates manually using a regression analysis formula

Space Toy Co.'s Methods

Space Toy Co. provided Proportional Value adjustments for unmatched female jobs, where necessary, by using the free-hand method and double-checking those results with a regression analysis program.

The next several pages will show you how each method works. After you've learned the different ways to do Proportional Value, you can use the interactive worksheet provided to calculate Proportional Value job rates using your own information.

The Interactive Worksheet

An interactive regression calculation worksheet is provided so you can:

  • enter male job classes, values and job rates
  • submit this data for calculation
  • enter female job classes, values and job rates
  • submit this data for calculation
  • calculate Proportional Value job rates for unmatched female job classes

The Proportional Value Process

Space Toy Co.'s unmatched female job classes were: Customer Service Clerk, Accounting Clerk, and Receptionist/Typist. Space Toy Co. began its Proportional Value process by choosing a representative group of male jobs and determining a pay pattern for these. This part of the process is shown on the next page.
