The QME package and Shiny UI for QME were created to provide a relatively easy-to-use tool for performing psychometric analyses in R under the Classical Test Theory framework. Although there are already several packages in R that can be used to carry out different parts of a psychometric analysis, there is not currently a package that provides practitioners with the comprehensive functionality to import and score test data, compute item- and test-level statistics, and perform distractor analysis. Faced with these challenges, faculty and graduate students at the University of Minnesota have been collaborating on finding better software solutions to drive broader adoption of psychometric practices. The QME package and Shiny UI fill this gap by allowing users to go from their raw un-scored item responses to a practical report with relative ease, providing a compelling open source alternative to commercial packages such as ITEMAN and SPSS.
