Since the early days of performance assessment, human ratings have
been subject to various forms of error and bias. Expert raters
often come up with different ratings for the very same performance
and it seems that assessment outcomes largely depend upon which
raters happen to assign the rating. This book provides an
introduction to many-facet Rasch measurement (MFRM), a psychometric
approach that establishes a coherent framework for drawing
reliable, valid, and fair inferences from rater-mediated
assessments, thus answering the problem of fallible human ratings.
Revised and updated throughout, the Second Edition includes a
stronger focus on the Facets computer program, emphasizing the
pivotal role that MFRM plays for validating the interpretations and
uses of assessment outcomes.
