What are Global Rating Scores?
In clinical skills or observational assessment, apart from item score sheets, Global Rating Scores (GRS) are used. A GRS reflects the professional opinion of the examiner once they have completed the item score list. This list represents what they have observed or marked during the scenario. In most cases, a 5 or 6 item Likert scale is used ranging from 0 = Fail; 1 = Borderline; 2 = Pass; 3 = Good to 4 = Excellent. Sometimes, if examiners can’t choose between Borderline and Fail or Borderline and Pass an extra option is brought into this GRS. Now examiners have the option to choose between 0 = Fail; 1 = Borderline fail; 2 = Borderline pass; 3 = Pass and 4 and 5 are Good and Excellent, respectively.
