Many Facet Rasch Measurement: a practical guide using FACETS

Participants will be introduced to some of the issues associated with involving human judges in the rating process in speaking assessment contexts. They will become familiar with the basic concepts in Many-Facet Rasch Measurement (MFRM) and will learn how to run the FACETS programme and to enter, analyse, and interpret test data with more than two facets e.g. candidates, raters, scoring criteria, tasks, etc. Participants will learn to evaluate the extent to which raters are consistent in their rating behaviour and whether they display systematic differences that can affect candidate scores.
