What is Rater Reliability?
Rater reliability is the concept that when something is being assessed, it would get the same accurate score, no matter who is doing the rating. If you were evaluating one of your Team Members, a sign of high rater reliability would be if another Manager gave the same scores in the evaluation of that same Team Member. Essentially, if you had the same information in front of you each time, you would give the same score. Ideally, we want to have high rater reliability as it means that we have accurate data and a clear picture of employee performance.
