Specialized Rasch Measures Applied at the Forefront of Education : Practitioners' Perspectives

Rasch models are used for analysing data from assessments to measure things such as abilities, attitudes, and personality traits. For example, they may be used to estimate a student's reading ability from answers to questions on a reading assessment, or the extremity of a person's attitude to capital punishment from responses on a questionnaire. Rasch models are particularly used in psychometrics, the field concerned with the theory and technique of psychological and educational measurement.
