Outline of Final Research Achievements

Any two different tests can be linked formally by applying equating methods. However, not only test scores but also linked scores should have a high degree of reliability to ensure meaningful linking. In this study, we focus on linear linking under single group design and propose a standard error of measurement and an index of reliability for linearly linked scores. Furthermore, we present applied examples that examine the linkability of linear linking from the perspective of reliability with the results of actual large-scale tests.
