Job evaluation is the process of analyzing and assessing jobs systematically to determine their relative worth. It provides objective measurements of jobs to establish fair pay structures. The main methods of job evaluation are ranking, classification, point, and factor comparison. Ranking simply ranks jobs, while classification matches jobs to predefined categories. Point and factor comparison methods assign numerical scores to jobs based on compensable factors like skills, effort, responsibility, and working conditions. The scores are used to group jobs into salary grades. The goal of job evaluation is to establish rational, consistent pay structures that reduce disputes.
