Research project The overall aim is to develop new efficient statistical methods within the area of psychometrics, in order to ascertain and guarantee high quality over time in large standardized achievement tests.
By creating a new way to model items we can give more understandable information to test takers. We can obtain fair tests in more situations by extending the framework of equating, i.e. methods used in order to adjust test scores from different test versions so they can be used interchangeably. In line with this we need tools to assess the equating transformations, which will be developed. Finally, to ascertain high quality over time it is planned to develop and adjust quality control methods so they are feasible to use with standardized achievement tests which are typically administrated several times and where the test takers results are valid many years.
