While it has many similarities with comparative rating systems, there are some key differences that make absolute ratings unique from others. Absolute rating is based on an employee's performance, skills, and overall contribution to the organization. These types of ratings are used in various industries, including banking, marketing and media, retail stores and medical sectors. 

Absolute HR rating system is considered as one of the most effective ways of measuring employee performance as it allows managers to give a more focused feedback while reviewing their staff's progress towards achieving agreed targets.
