Abstract [en]

The goal of this workshop is to introduce equating and to provide the necessary tools to be able to perform different equating methods in practice by using available R packages. The aim of test equating is to adjust the test scores on different test forms so that they can be comparable and used interchangeably. Equating has a central role in large testing programs and it constitutes an important step in the process of collecting, analyzing, and reporting test scores. Equating is important as it ensures a fair assessment regardless the time, place or background different test takers might have. Through a number of examples and practical exercises, attendees will get both a conceptual and practical understanding of various equating methods conducted under different data collection designs. The R software will be used throughout the session with special focus on the packages; equate, kequate, SNSequate and equateIRT. The training session follows some of the chapters in the book Applying test equating methods using R which has been written by the instructors and was released in 2017 by Springer.
