Rater measurement report (Table 7.2.1 on FACETS). Figure 2 displays important rater-related indices including rater severity measures and fit statistics. Particular attention is given to the first column titled “measure” displays each rater’s severity measures in log-odd units. Rater separation index indicates a number of distinct strata of severity. The fixed (all same) chi-square statistics tests if the raters significantly differ in their severity levels
