This handbook for learning how to do Rasch measurement contains both theoretical explanation and practice problems. It is about how to make use of mental tests, and covers the measurement model, item calibration by hand and by computer, the analysis of fit, and constructing a variable. Final chapters work through designing tests, making measures and choosing a scale.

This book is a text about constructing variables and making measures. The basis is the measurement philosophy of G. Rasch. The text begins by outlining the essentials for measurement, examining data and developing models for measuring, and covers estimation procedures, verifying variables and supervising measures. The authors extend Rasch item analysis and person measurement to attitude questionnaires, performance ratings and other ordered category data.
