Inter-rater reliability is the extent to which two or more raters (or observers, coders, examiners) agree. It addresses the issue of consistency of the implementation of a rating system. eg.

Internal consistency is typically a measure based on the correlations between different items on the same test eg. customer care service assessment in a call centre
