Research Framework - Scoring and Reporting

Linking

This research area is concerned with finding a common scale to link two forms that are putatively measuring the same knowledge and skills. Research on linking and equating is invariably strongly tied together with each other, and also with scaling research. These areas also have a strong interaction with test assembly, because the assembly process is often done in the context of producing approximately parallel forms.
