It is often advantageous to measure a single construct through multiple assessments that capture its interrelated conceptual features. When multiple scores are used to assess a construct, however, researchers should consider how similarly the scores behave relative to that construct. For instance, a researcher might administer a computer literacy test consisting of five modules assessing different computing skills, yet the scores of each module might relate differently to the construct of computer literacy. Deciding on what assumptions are met about the equivalence of each module’s scores as reflections of computer literacy is a crucial step, as these assumptions directly impact how the internal consistency of the computer literacy test is computed. In this context, tau equivalence refers to the stringency of assumptions used in calculating ...
