Rating scales provide a systematic way to assess individuals or objects by having raters assign scores or descriptions. There are different types of rating scales such as descriptive, graphical, comparative, and numerical scales. Rating scales can be used to evaluate performance, skills, attitudes, interests and personal characteristics. They are useful for assessing students, employees, and research subjects. However, rating scales also have limitations as it can be difficult to rate all aspects of a person objectively and consistently between raters.
