The Philosophy of Inter-rater Agreement
There are several operational definitions of "inter-rater reliability" in use by Examination Boards, reflecting different viewpoints about what is reliable agreement between raters.
There are three operational definitions of agreement:
1. Reliable raters agree with the "official" rating of a performance.
2. Reliable raters agree with each other about the exact ratings to be awarded.
3. Reliable raters agree about which performance is better and which is worse.
These combine with two operational definitions of behavior:
A. Reliable raters are automatons, behaving like "rating machines". This category includes rating of essays by computer . This behavior can be evaluated by Generalizability theory.
B. Reliable raters behave like independent witnesses. They demonstrate their independence by disagreeing slightly. This behavior can be evaluated by the Rasch model.

Famous quotes containing the words philosophy and/or agreement:
“The literature of the poor, the feelings of the child, the philosophy of the street, the meaning of household life, are the topics of the time. It is a great stride. It is a sign,—is it not? of new vigor, when the extremities are made active, when currents of warm life run into the hands and the feet.”
—Ralph Waldo Emerson (1803–1882)
“There’s nothing is this world more instinctively abhorrent to me than finding myself in agreement with my fellow-humans.”
—Malcolm Muggeridge (1903–1990)
