What is Inter-Rater Reliability

Inter-rater reliability is the degree of agreement among independent reviewers who rate or assess the same body of work.

Rubrics and other assessment tools that rely on ratings must exhibit good inter-rater reliability, otherwise they are not reliable evaluations. There are a number of statistical methods that can be used to calculate inter-rater reliability. Different statistics are appropriate for different types of measurement.
