Summary and Conclusions
This investigation is a validity study in at least two senses. First, it aimed to be “a scientific inquiry into score meaning” (Messick, 1989a; see also, Messick, 1989b, pp. 21–34). Second, the close attention we have paid to the test development process, by, for example, modeling and documenting the expertise of those involved in the creation of items, adds to the “operational validity” of GRE test scores. In this chapter we will attempt to put the study into perspective and summarize its results.
