Abstract
The rater and item measurement reports which are produced by Facets are very similar to the item and person statistics (Tables 13.1 and 17.1) we met in Winsteps. They provide information about the person-ability measures of the raters which in turn tells us how severe or lenient they have rated a task or performance. They can also tell us about the difficulty level of the items or task type (article, report or essay).
