A job evaluation scheme determines the relative value of jobs within an organisation in a consistent way.
The employer should consider the objectives, risks, costs and scope of the project before deciding how to proceed.
Job evaluation schemes can be proprietary (designed by a consultant or other external organisation), in-house or a mixture of the two.
In order to provide an effective defence against an equal pay claim, a job evaluation scheme needs to be non-discriminatory and break jobs down into their core components.
