The Rasch model , named after Georg Rasch , is a psychometric model for analyzing categorical data , such as answers to questions on a reading assessment or questionnaire responses, as a function of the trade-off between a the respondent's abilities, attitudes, or personality traits and b the item difficulty. In addition to psychometrics and educational research, the Rasch model and its extensions are used in other areas, including the health profession [2] and market research [3] because of their general applicability. The mathematical theory underlying Rasch models is a special case of item response theory and, more generally, a special case of a generalized linear model. However, there are important differences in the interpretation of the model parameters and its philosophical implications [5] that separate proponents of the Rasch model from the item response modeling tradition. A central aspect of this divide relates to the role of specific objectivity, [6] a defining property of the Rasch model according to Georg Rasch , as a requirement for successful measurement.

The purpose of this book is to illustrate techniques for conducting Rasch measurement theory analyses using existing R packages. The book includes some background information about Rasch models, but the primary objective is to demonstrate how to apply the models to data using R packages and interpret the results. The primary audience for this book is graduate students or professionals who are familiar with Rasch measurement theory at a basic level, and who want to use open-source software to conduct their Rasch analyses. We provide a brief overview of several key features of Rasch measurement theory in this chapter, and we provide descriptions of basic characteristics of the models and analytic techniques in each of the following chapters. Accordingly, we encourage readers who are new to Rasch measurement theory to use this book as a supplement to other excellent introductory texts on the subject that include a detailed theoretical and statistical introduction to Rasch measurement. For example, interested readers may find the following texts useful to begin learning about Rasch measurement theory:. Andrich, David, and Ida Marais.

A Course in Rasch Measurement Theory

This essay describes Rasch analysis psychometric techniques and how such techniques can be used by life sciences education researchers to guide the development and use of surveys and tests. Specifically, Rasch techniques can be used to document and evaluate the measurement functioning of such instruments. Rasch techniques provide a mechanism by which the quality of life sciences—related tests and surveys can be optimized and the techniques can be used to provide a context e.
