""No author can match George Engelhard’s oeuvre in the use of Rasch models for rater-mediated performance assessments. This latest volume, with Stefanie Wind, draws on a broad background of measurement theory, philosophy and test standards to focus invariant measurement – the crucial next step in measurement practice. This will be my go-to reference text."" - Trevor G. Bond, James Cook University, Australia ""This is an accessible and comprehensive treatment on the use of ratings for measurement purposes. The authors are trusted sources who are active in the field and that practical knowledge and experience shows in their writing."" – Jonathan Templin, University of Kansas, USA
